Sailing Terms Everyone Should Know

By: American Sailing Sailboats

Knowing the right sailing terms to use on board a boat is not JUST a way of sounding super cool and impressing your friends. (Though it works for that, too.) It’s actually very useful, and sometimes crucial in communicating while you’re sailing. Some of the vocabulary used on board boats can sound arcane, which it is! That’s part of what’s fun about it; we’re still using terms that have been used by sailors for hundreds of years. So when you know your terminology, you’re participating in the grand sailing tradition, and you don’t have to say, “Can you hand me that…thing?”

Here are the key sailing terms you’ll want to know as you begin learning to sail !

• Port: Facing forward, this is anything to the left of the boat. When you’re onboard, you can use this term pretty much any time you would normally say “left.” Starboard: Facing forward, this is anything to the right of the boat. Same deal as “port”–only the opposite.
• Bow/Stern: The bow is the front of the boat, the stern is the back. Anything near the front of the boat is referred to as being “forward,” and anything toward the back is “aft” or “astern.”
• Point of Sail: The boat’s direction relative to the wind. For example, if you’re going straight into the wind, your point of sail is called “in irons.” (Note: This isn’t a good place to be!) If the wind is blowing straight over the side of the boat, that’s called a “beam reach.” There are 8 commonly used points of sail, and it’s a good idea to familiarize yourself with them before going out.
• Helm: Where you steer the boat. Usually this is a big wheel, but on smaller boats it can be a tiller, which is basically a long wooden stick. Either of these can be used to control the boat’s rudder.
• Keel: The keel is a long, heavy fin on the bottom of the boat that sticks down into the water. It provides stability and is the reason why modern sailboats are nearly impossible to capsize.
• Heeling: This is the term for when a sailboat leans over in the water, pushed by the wind. There’s nothing else like the thrill of heeling over as your sails fill and your speed picks up!
• Tack: This term has two distinct meanings, both of them very important. As a verb, to tack is to change direction by turning the bow of the boat through the wind. As a noun, your tack is the course you are on relative to the wind. For example, if the wind is blowing over the port side, you are on a port tack. If it’s blowing over the starboard side, you’re on a…you guessed it…starboard tack.
• Jibe: A jibe is another way of changing direction, in which you bring the stern of the boat through the wind. Whether you choose to tack or jibe entirely depends on the situation–what’s around you, and the direction of the wind.
• Windward: The side of the boat closest to the wind. When heeling over, this will always be the high side.
• Leeward: The side of the boat furthest from the wind. When heeling over, this will always be the low side.
• Lines: On board a boat, this is what you say instead of “ropes.”
• Mainsail: The big triangular sail just aft of the sailboat’s mast. As the name suggests, this is the boat’s largest and most important sail. Running along its bottom edge, the mainsail has a thick pole called the boom.
• Jib: The next most common sail on any boat. The jib can always be found forward of the mast, and unlike the mainsail, does not have a boom.

  Getting familiar with these sailing terms is an important step. Not only will you sound like you know what you’re doing, you’ll quickly begin to realize that with the right practice and training, you really DO know what you’re doing!

Sailing Terms: A Complete Guide

Last Updated by

June 15, 2022

Learning sailing terms when you first get into boating can be a daunting task.

Some sailing terms are logical, like 'fore' means forward or front of the boat, while others might as well be in a different language. Athwartship, for example. Nothing in our daily lexicon gives any clues as to what that might mean. Like it or not, it's time to dust off the old noodle and get to memorizing some new vocab words!

Knowing the difference between a clew and a tack, a luff and a leech, will help you communicate with your sail maker regarding which part of your sail needs resewn. If you need to have your rigging adjusted, you must know the difference between your shrouds and your stays, your standing rigging vs. your running rigging.

By educating yourself in the correct names of all parts of your sailboat, you can avoid situations in which you may need to use terms such as ‘thingy’ or ‘that round part at the end of that thing’. While even the most seasoned sailor occasionally troops over the vernacular, it is always beneficial to have as wide a nautical vocabulary as possible. Many in the sailing community get by without knowing the entire sailing dictionary, but if you’re interested in avoiding vocabulary embarrassment, check out the list I’ve compiled of sailing terms that every sailor ought to know.

I’ve been sailing on and off throughout my life and I know from experience that it is incredibly helpful to know the correct terms for each part of your sails, rigging, and boat.

Sailors are among the kindest, most helpful people you’ll ever meet. But, if you’re looking for help on why you’re not getting the most speed out of your mainsail and you know don’t know the correct terms for each part of the sail, it may be hard to get advice from you fellow sailor on why ‘the back of the mainsail is flappy’. They would be more likely to give useful advice if you’re able to tell them that you’re struggling to keep wind in the roach of your mainsail. Check out my list of sailing terms and see if a few don’t stick. I’ve done my best to include pictures when possible.

Table of contents

Sailing Terms

Abeam : When an object, craft or island is abeam your vessel, that means that it is off the side of your boat. It is 90 degrees from the centerline of your boat.

Abaft : Toward the stern. “Honey, have you seen my boat shoes?” “They’re abaft the navigation table!” This is the opposite of forward.

Aft : In the stern of the boat. For example, the back cabin is referred to as the aft cabin.

Apparent wind : The wind direction and speed which the crew observes to be blowing in combination with the true wind. This is often different from the true wind direction and speed due to the boat's motion.

Astern : The area behind the boat. If you go astern, you are going in reverse.

Athwartship : Directionally perpendicular to the centerline of the boat.

Backing (a sail) : Forcing the sail to take wind into its opposite side by pulling the sail to the opposite side of the boat.

Backstay : The wire that runs from the back of the boat to the mast head. This prevents the mast from falling forward.

Bailer : Any scoop-like container that is used to remove water from within a vessel’s hull.

Ballast : Weight which adds stability to the vessel. The weight usually is composed of lead or iron and placed low in the boat's hull, such as within the keel.

Batten : a thin, flexible strip (often fiberglass) that is inserted into the main sail to help it stay open to the wind. The batten runs from the back edge of the sail (leech) toward the front edge (luff).

Beam : The width of the vessel at its widest point.

Beam reach : Sailing with the wind blowing perpendicular to the direction the boat is traveling.

Bearing off or Bearing away : Steering the boat away from the direction in which the wind is blowing.

Boot Top or Boot Stripe : The stripe of tape or paint between the boat's underwater (bottom) paint and it’s above water (topside) paint.

Bow : Front end of the boat

Bowsprit : The forward most protruding pole or platform which some boats possess. This spar allows for the sails and rigging to be attached further forward.

Broach : When a boat sailing downwind accidentally ends up sideways to the waves and heels over dangerously. This can be caused by large seas or poor steering.

In-Irons : When a sailboat is bow into the wind with sails flapping. No steerage is possible as the vessel has no forward motion. (See Points of Sail for infographic.)

Jackline or Jackstay : Lines that are run from the bow to the stern. To these safety lines, sailors attach a lanyard connected to their harness so that they may work on deck without fear of being swept overboard in rough seas.

Jib : A triangular forward sail.

Jib sheets : Lines used to control the jib.

Jibing : Pronounced with a long i sound. Steering the boat from one downwind direction to another downwind direction by turning the stern of the boat through the wind. This will cause the sails to move across the boat to the other side, i.e. from port to starboard.

Kedge anchor : A small, lighter second anchor.

Keel : The bottom most part of a boat's structure. This part provides ballast and stability.

Ketch : A sailboat with two masts. The forward mast is the taller mast.

Knot : Regarding speed, one knot is equal to one nautical mile per hour.

150+ Nautical Terms: Illustrated Guide

Sailing and nautical terms have been refined over centuries, forming a unique glossary that can leave even the most seasoned wordsmiths scratching their heads.

Today, we’ll look at the terminology of words and names used at sea to help you through even the saltiest conversations.

Terms for the components a sailboat consists of

Let’s start with terms for the parts a sailboat is put together from. These refer to each component and explain what they are.

The main parts

Mast : The mast is the big, tall spar that holds up the sails! Some boats have more than one mast.

Mainsail:   The mainsail is the sail behind the mast and on top of the boom. Often just referred to as “the main.”

Boom:  The spar that sticks out behind the mast.

Rudder:  The rudder is also a fin sticking down under the boat but is located back towards the stern and connected to the wheel or tiller, enabling you to steer the vessel.

Headsail:  The sail(s) in front of the mast. Many boats have more than one headsail and can be of different sizes and shapes.

Spreader:  The fins or wings that space the shrouds out from the mast.

Hull:  This is the body or structure of the boat. Monohulls have one hull, catamarans have two hulls, and trimarans have three hulls – you get the point.

Keel : This is the heavy fin sticking down under the middle of the boat, allowing it to sail. There are many different keel designs, but they are all heavy, and their job is to keep the vessel stable and track through the water under sail.

Helm: This is the position where you steer the boat. Usually, this is a wheel, but it can also be a tiller on many vessels.

Cockpit: The cockpit is the boat’s steering position and where you will find the helm.

Transom: The flat surface across the stern of the boat.

Bow and Stern: The bow is the front part of a boat, while the stern is the rear end. 

Midship:  By some called amidships – The center of the boat.

Beam: The widest part of the boat. It is also referred to as the sides on the middle of the vessel.

Waterline: This is the part where the hull (body) of the boat meets the water. Many ships have a painted stripe to mark the waterline, indicating the boat’s load. If you have too much stuff on board, the waterline goes underwater, and it is time to do some housekeeping!

Freeboard: The vertical part of the ship side between the water and the deck.

Deck: The deck is the “floor” of the boat when you are outside. You have probably heard the term “All hands on deck!”

Spar: The general term for a pole made of a solid material like wood or metal used to support a boat’s sail. The mast, boom, spreaders, etc., are defined as spars.

Gooseneck:  This fitting connects the boom to the mast and allows it to move horizontally and vertically.

You can read more about the different parts of a sailboat in this article.

The standing rigging which holds the sails

Forestay:  The forestay   is a wire that runs from the bow to the top of the mast. Some boats, like the Cutter rig, can have several additional inner forestays in different configurations.

Furling system:  Most sailboats have their headsail on a furling system, a tube running along the forestay from the bottom furler drum to the masthead swivel. 

Backstay/Aft stay:  The wire that runs from the aft of the boat up to the top of the mast.

Shrouds:  On most common cruising boats, there are usually four shrouds on each side to support the mast from sideways motion. The shrouds are generally made of wire but can also be rods or Dyneema lines. The  cap shrouds  run from the masthead through the tips of the spreaders down to the deck. The  intermediate shrouds  run from the lower part of the mast, through the lower spreaders, and to the deck. The  lower shrouds  run from the mast under the lower spreaders down to the deck – one forward and one aft on both sides. This is called  continuous rigging .

Turnbuckle:  The fitting that connects the shrouds to the  chainplate  on the deck. These are adjustable, allowing tensioning of the rig.

Chainplate:  A fixed strong point bolted on the deck. Usually reinforced with a backing plate underneath. 

You can read more about the standing rigging in this article .

The running rigging which operates the sails

Line:  The running rigging on a sailboat often consists of lines, a type of rope with a smooth surface that works well when used on a winch. 

Halyard:  This is the line you use to hoist and lower the sail. 

Sheets:  The sheet is the line you use to  control a sail . The  mainsheet  controls the angle of the mainsail and is attached between the boom and the  mainsheet   traveler . The two headsail sheets are connected to the sail’s clew (lower aft corner) and run back to each side of the cockpit.

Outhaul:  The outhaul is attached to the clew of the mainsail and used to adjust the foot tension. 

Topping lift:  A line attached to the boom’s end runs through the masthead and down to the deck or cockpit. Used to lift and hold the boom and also function as a spare main halyard.

Downhaul:  A line used to lower with. Typically used to lower the mainsail when reefing and lowering the spinnaker and whisker poles.

Reef line:  Depending on your setup, these lines are used to reduce the sail area of the mainsail.

Shaking a reef: When we sail with a reefed sail and want to increase the sail area back to full, we call it shaking the reef.

Equipment used to operate the running rigging

Block:  A pulley with a sheave wheel. These are used to change the direction of a pull on a line or rope and give a mechanical advantage. 

Mainsheet Traveler:  The traveler is a horizontal track attached to the mainsheet through a series of blocks. The traveler enables you to adjust the boom from side to side or lock it at an angle.

Cars:  The cars are pulleys or blocks attached to a track on the side decks that your headsail sheets run through. They are used to control the angle of the sheet between the clew and the deck. 

Jammer:  The jammer is used to lock a line in place. Most sailboats use these for locking the halyards, mainsheet, outhaul, reef lines, traveler lines, boom vang lines, etc. 

Spinnaker Pole:  A spar used to wing out a headsail when sailing off the wind, particularly the Spinnaker. 

Whisker Pole:  Similar to the spinnaker pole, but typically built lighter and attached to a track on the mast. These can be found in fixed lengths or adjustable lengths. 

Boom Vang/Rod Kicker:  A compression pole is used to tension the boom downwards. 

You can read more about the running rigging in this article.

Deck gear and hardware

In-mast furling:  A furling system that furls the mainsail in and out of the mast as opposed to the traditional way where the mainsail is secured to the boom and is hoisted and lowered on a track behind the mast.

In-boom furling:  A furling system that furls the mainsail in and out of the boom. 

Stack Pack:  Also called  Lazy Bag or Lazy Pack . A bag with a zip attached to the boom where the mainsail is stored when unused.

Lazy Jacks:  A set of lines running from the stack pack to the mast guides the mainsail up and down from the Stack Pack and prevents it from falling on the deck. 

Masthead:  Not to be confused with the term masthead rigging. Out of context, the masthead is the top of the mast.

Winch:  A metal drum that gives you a mechanical advantage when tightening lines.

Sprayhood:  The windshield of the boat that protects the people in the cockpit from sea spray. Some ships have canvas spray hoods that can be folded down or removed. Others have solid sprayhoods, often called a  hard dodger  or a  doghouse .

Bimini:  The cockpit’s roof protects you from the elements and provides shelter from spray, rain, and burning sun rays! A bimini can be made of canvas or hard material. The hard bimini is usually called a  hardtop .

Outboard:  Short-term for an outboard engine, which usually belongs to the dinghy.

Cruisers:  What we sailors often call ourselves. Especially those of us living onboard. Although salty, we are definitely handy to have on board as we are also electricians, mechanics, plumbers, and you name it.

Fenders:  Like Captain Ron said in the movie, the rubber bumper things you hang off the side of your boat to prevent it from scratching against something like the key side or another boat. Conveniently also used to sit on or as a backrest while relaxing on the deck.

Boat Hook:  A long stick with a hook at the end. Used to grab lines, items, and stuff that is too far to reach by hand, like cushions flying overboard. It is also convenient as a tool to push the boat away from another ship or the key. Or to push mud or clay off the anchor . Or catch a wild flying halyard. Most vessels have them on board, and you want one or two. (They tend to get lost at sea).

Guard Rail:  This can be a flexible wire or a solid metal rail surrounding the boat to prevent us from falling overboard. Some also use a net as an addition for increased safety.

Pushpit:  The metal guard rail around the stern of the boat. This is where the guard rail is secured on the stern. A common place to mount the BBQ, life raft, and the outboard for the dinghy. 

Pulpit:  The metal guardrail on the bow. This is where the guard rail is secured onto the bow.

Stanchion:  The metal bar that keeps the guard rail in place around the boat between the pushpit and the pulpit.

Arch:  A big structure usually made of stainless steel on the back of a boat. Often used to mount a variety of items like antennas, radars, solar panels, wind generators, etc.

Ground Tackle:  This consists of your  anchor , your anchor  chain,  the link between the two, and the connection between the chain and your boat. The ground tackle is basically the system that holds your boat to the ground.

Windlass:  The winch that hoists or lowers the anchor and chain. Most boats have one on the bow, and some have one on the stern, too. These incredible things can be electrical or manual (some are both) and are essential to anchor your boat when not in a port or marina. Try to haul the anchor manually once – you’ll put a windlass on the top of your wish list pretty quickly…

VHF   Radio:  Very High-Frequency Radio that broadcasts on the VHF network and makes you able to communicate with others around you. Sadly, you won’t be able to tune in to your favorite radio show on these. Still, they are invaluable at sea for communication.

Chart Plotter:  A navigation computer that shows various information on a screen, like charts, routes, radar images, etc.

Parts below the decks

Companionway:  The “front door” of the boat. This is where the steps lead from the cockpit or deck down below. It is usually opened and closed using a hatch, two doors, or a plate.

Galley:  The kitchen of a boat is never to be called a kitchen. Always use the term galley when you are onboard!

Saloon:  This is the boat’s living room and usually where you find the settee and dinette.

Settee:  The couch in a ship.

Dinette:  This is the area where you can sit down at a table and eat your dinner. It’s also perfect for consuming rum in good company and a game of cards.

Cabin:  These are the “rooms” onboard but might not necessarily be the “bedrooms.”

Head:  There are no bathrooms on a boat, only heads. If your skipper tells you to go and clean the head, getting out the shampoo won’t do you any good.

Nav station:  Usually a chart table and a console with mysterious instruments like radios, chart plotters, radar screens, and all sorts of complicated electronics. This is often where adventures are planned and the skipper’s favorite seat onboard. (At least, that is my favorite and where all this content is created!).

Bilge:  The space in the bottom of the hull where water collects and sometimes a storage space for all sorts of things. It usually contains a  bilge pump  to pump out water that finds its way into the boat in various places. You may have heard the phrase: “Treasures of the bilge.” Now you get it!

Berth:  A place in the boat where you can sleep. This doesn’t necessarily have to be a bed and can often include the sleeping space in the salon. The term  sea-berth  usually refers to a sleeping position where you are tucked well in and can sleep when the boat is heeling over and moving around.

V-berth:  The bed in the front cabin is shaped like a V.

Bulkhead:  A wall inside the boat, usually supporting the structure.

Terms used for directions and navigation

Port and Starboard : Port refers to the left side of the boat when facing the bow (front), while starboard signifies the right side. 

Windward and Leeward : The windward side refers to the side of a boat facing the wind, while the leeward side is the side sheltered from the wind. These sailing terms also apply to geographic features, like islands or coastlines, that offer protection from the wind.

Chart : A nautical chart is a map specifically designed for marine navigation, depicting water depths, shoreline features, navigational aids, and potential hazards.

Compass : A compass is an essential navigational instrument that indicates magnetic north, allowing sailors to determine their heading and steer their vessels accordingly.

Course : The course is a vessel’s intended direction of travel, expressed in degrees from true or magnetic north.

Heading : The heading is the actual direction a vessel points, also expressed in degrees from true or magnetic north.

Latitude : Latitude is a geographic coordinate that specifies a location’s distance north or south of the equator, measured in degrees, minutes, and seconds.

Longitude : Longitude is a geographic coordinate that specifies a location’s distance east or west of the Prime Meridian, measured in degrees, minutes, and seconds.

Waypoint : A waypoint is a specific location, defined by its latitude and longitude, that serves as a reference point for navigation.

Bearing:   The angle between the observer’s position and a distant object, measured in degrees from true or magnetic north.

Fix : A fix precisely determines a vessel’s position using various navigational methods, such as bearings, GPS, or visual landmarks.

Dead Reckoning : Dead reckoning is a method of estimating a vessel’s current position based on its previous position, speed, and course over time.

Tide : Tides are the regular rise and fall of sea levels caused by the gravitational forces exerted by the Moon and Sun. 

Current : Current refers to the horizontal movement of water in a particular direction. Currents can significantly affect a vessel’s speed and course, so make sure to consider them when sailing and navigating.

Buoy: A buoy is a floating device anchored in a body of water, such as an ocean, sea, lake, or river, to serve various purposes, including navigation, marking channels, identifying hazards, or indicating mooring locations.

The names of different sails and their parts

Mainsail:  The mainsail is the sail behind the mast and on top of the boom. 

Genoa :  A Genoa is a headsail that extends past the mast and overlaps the mainsail. 

Jib :  A Jib is a headsail that does not overlap the mainsail. 

Staysail:  A staysail is usually found on cutter rigs and is the sail set on the inner forestay.

Yankee:  A yankee headsail is used similarly to a Genoa or Jib but has a high-cut clew and is often used on cutter-rigged boats together with a staysail.

Mizzen sail:  A mizzen sail is typically a small triangular sail set on the aft mast of a boat with several masts, like the ketch rig.

Storm sail:  A storm sail is a small, strong sail to be used in heavy weather conditions where the headsail is furled to the point where its shape doesn’t give you drive anymore or/and when you want a smaller mainsail than your reefing setup allows you. The storm sails provide stability in the vessel in heavy weather sailing.

Spinnaker:  A Spinnaker is a symmetric light wind sail used to sail off the wind at deep angles between 120 and 180 degrees.

Gennaker:  A Gennaker is a cross between the Genoa and Spinnaker. It has the same type of light fabric as the Spinnaker but is asymmetrical like a Genoa with a tack set on the bow and a sheet led back from the clew to the stern of the boat.

Code Zero:  A code zero sail is a cross between a Genoa and a Gennaker. It is also designed for light wind with its lightweight fabric but has a different shape than a Gennaker. This makes it able to be used while sailing upwind, unlike the Gennaker.

Parasailor:  A parasailor is similar to a spinnaker but with some differences. It has a double-layer wing that inflates as the sail gets filled with air. This wing works like a batten and keeps the leech out while generating lift on the bow, making it effective between 70 degrees and all the way down to 180 degrees dead downwind.

The different parts of a sail

Tack:  The tack of the sail is the lower forward corner.

Clew:  The clew of a sail is the lower aft corner.

Head:  The top corner of a sail. 

Foot:  The foot of the sail is logically the bottom part of the sail between the clew and the tack.

Luff:  The luff is the front edge of the sail between the tack and head.

Leech:  The leech is the aft part of the sail between the clew and head. 

Telltales:  Telltales are small ropes, bands, or flags attached to the sail to give you an indication of the airflow around your sail. 

Battens:  Battens are slates or tubes inserted in pockets on the mainsail to help it keep its shape better and increase its lifespan.

Terms used when we talk about wind and weather

Gust : A gust is a sudden, brief increase in wind speed, often accompanied by a change in direction.

Squall : A squall is a sudden, strong wind that typically lasts for a short period and is often associated with rapidly changing weather conditions, such as thunderstorms or cold fronts.

Barometer : A barometer is an instrument used to measure atmospheric pressure. Changes in atmospheric pressure can indicate upcoming weather changes.

High-Pressure System : A high-pressure system is an area of relatively high atmospheric pressure, characterized by sinking air and typically associated with calm, clear weather.

Low-Pressure System : A low-pressure system is an area of relatively low atmospheric pressure, characterized by rising air and typically associated with clouds, precipitation, and potentially stormy conditions. Sailors usually refer to these systems as a “low.”

Front : A front is a boundary separating two air masses of different temperatures and humidity levels. Fronts are associated with changes in weather conditions and can cause sudden wind shifts and varying wind strengths.

True Wind Speed, or TWS: The actual wind speed affecting you at a point when you are standing still.

True Wind Direction, or TWD: The direction the wind is blowing from.

True Wind Angle, or TWA: The angle between your boat’s heading and wind direction.

Apparent Wind Speed, or AWS: The wind affecting the boat while in motion.

Apparent Wind Direction, or AWD: The direction of the wind in relation to your boat underway.

AWA  –  Apparent Wind Angle: The angle to wind while you are underway

Beaufort Scale : The Beaufort Scale is a system used to measure wind speed, ranging from 0 (calm) to 12 (hurricane). You can learn more about it at MetOffice here .

Saffir Simpson Hurricane Wind Scale: A scale describing hurricane wind speeds in categories from 1 to 5.

Learn more about the difference between actual and apparent wind in this guide .

Terms we use when cruising at speed under sail

Port Tack:  When the wind blows on the port side of your sails

Starboard Tack:  When the wind blows on the starboard side of your sails

Tacking: When you steer the boat from a starboard tack to a port tack and vice versa  upwind .

Gybing:  When you steer the vessel from a starboard tack to a port tack and vice versa  downwind .

Heeling : When the wind fills the sails and leans the boat over to the side.

NM:  Nautical Miles

Kt:  Knots – A measurement of speed used on boats.

Deg: Short for degrees

SOG: Speed over Ground, usually measured by GPS

SOW:  Speed over Water, usually measured by the boat’s speed log transducer.

COG:  Course Over Ground, the direction your boat is  moving  towards.

HDG:  Heading, the direction your boat is  pointing  towards.

Boom preventer:  A line or rope tied to the end of the boom and led forward of the mast to prevent it from swinging over when sailing off the wind.

Overpowered:  When wind overpowers the boats’ ability to steer a straight course. This typically happens when you try to sail above your boat’s hull speed, carrying too much sail area in relation to the wind, or your sails are poorly trimmed.

Hull Speed: The speed your boat has achieved when its created wave has the same length as the hull’s water length. Many displacement sailboats (the ones that don’t plane on top of the water) get hard to steer when going faster than this. You can learn more about how to calculate your hull speed in this guide: https://sailingellidah.com/average-distance-sailed-in-a-day/

Pro Tip:  Your COG and HDG will sometimes differ due to wind and current pushing you sideways.

Terms for the boats heading in relation to the wind

These sailing terms are best known as our points of sail and describe the vessel’s heading in relation to the wind:

Close Hauled:  When sailing close-hauled, the vessel’s heading is as close to the wind as possible, typically between 35-50 degrees.

Close Reach:  When sailing at an angle between 50 and 80 degrees, give or take.

Beam Reach:  The wind comes in from the side.

Broad Reach:  When bearing away from 90 degrees to around 135 degrees.

Running:  When sailing downwind.

Sailing Terms and Phrases: A Comprehensive Guide to Nautical Jargon

by Emma Sullivan | Jul 19, 2023 | Sailboat Racing

Short answer sailing terms and phrases:

Sailing terms and phrases refer to language specific to the sport of sailing. They include terms related to boat parts, sailing maneuvers, wind direction, and navigation. Understanding these terms is crucial for effective communication and safe sailing practices.

Understanding the Basics: A Guide to Sailing Terms and Phrases

Welcome aboard, fellow sailors and landlubbers alike, as we embark on a voyage through the mesmerizing world of sailing terms and phrases. Whether you’re an enthusiastic beginner or a seasoned seafarer looking to brush up on your nautical knowledge, this guide will have you speaking like a true sailor in no time.

As with any specialized field, sailing has its own unique language that can bewilder even the most erudite wordsmiths. But fear not! We’re here to break down the basics and shed light on those mysterious terms that have been floating around in your mind like buoys at sea.

Let’s start by hoisting the main sail and diving headfirst into some essential terminology:

1. Port and Starboard: If someone shouts “Hard to port!” during your sailing adventure, don’t panic – they simply mean turn left. In maritime lingo, “port” refers to the left side of a vessel when facing forward, while “starboard” is the right side. Thinking of them as counterparts can help avoid confusion during moments of high-seas excitement.

2. Bow and Stern: Don’t forget where your front and back are while navigating the open waters. The bow is the forward part of the vessel (a great spot for taking epic photos), while the stern is located at the rear. Trust us – being able to differentiate between these two proves invaluable when following directions or describing intriguing sights.

3. Aft vs Forward: Just as knowing which way is up is vital for surviving gravity’s pull, understanding aft (the back part of a ship) versus forward (the front part) is crucial aboard a boat too! Being able to navigate with ease relies heavily on using these terms correctly when maneuvering around onboard.

Now that we’ve set our bearings straight let’s proceed further into more advanced seamanship jargon:

4. Shiver me Timbers: Ahoy, matey! Surely, you’ve heard this catchy phrase in pirate movies or read it in adventure novels. But do you know what it means? “Shiver me timbers” originated from the old seafaring days when wooden ships were prevalent. When they were hit by fierce storms or cannonballs, the creaking and vibrations of the hull made the timber “shiver.” Nowadays, it’s an exclamation expressing surprise or disbelief.

5. Nautical Mile: Avast, ye landlubbers! A nautical mile is a unit of measurement used specifically for sea and air travel. It’s equal to one minute of latitude along any meridian – approximately 1.15 statute miles (or about 1.85 kilometers). So, whether you’re voyaging across vast oceans or navigating through treacherous straits, understanding this term will keep you on course.

6. Windward and Leeward: When sailing the high seas, understanding wind patterns becomes crucial to harnessing their power effectively. Windward refers to the direction from which the wind is blowing (usually against your face), while leeward indicates the sheltered side where the wind is blocked by your vessel or other objects nearby. Skippers who can master these concepts will navigate their vessels with grace and ease.

7. Keelhaul: Now here’s a term that harkens back to darker maritime times! To keelhaul someone often meant dragging them under a ship’s keel as a form of punishment. Luckily for us nowadays, it has mostly been relegated to seafaring folklore and modern-day sailors rarely seek to employ such discipline.

So there you have it – a comprehensive yet entertaining guide to essential sailing terms and phrases that will surely make waves amongst your fellow salts-in-arms! From knowing your port from starboard all the way down to deciphering historical jargon like “shiver me timbers,” embracing these nautical expressions will not only deepen your understanding but also add a touch of maritime flare to your conversation.

So raise your glasses – or rather, yer grog – as you confidently navigate the mighty seas armed with newfound knowledge, humor, and a dash of seafaring slang. Bon voyage!

By employing phrases such as “the sea rose like a mighty kraken” or “whispering zephyrs guided our course,” you’ll be painting masterpieces with words.

3) Channeling History’s Echoes: The language of sailing is deeply rooted in history, connecting us to generations past who braved unforgiving waters aboard wooden vessels. Embracing these linguistic relics imbues your journey with a sense of timelessness and reverence for those who came before us. Employing phrases like “avast ye scurvy dogs” or “there she blows!” lets you channel the spirit of earlier sailors, forging an indelible bond across ages.

4) The Poetry of Seamanship: Sailing brings together the precision of a science and the lyricality of art, creating an environment where language emotively intertwines with experience. By embracing sailing terms, you’ll find yourself effortlessly conversing in poetic cadences – from referring to land as the “shores of belonging” to desiring nothing more than catching a glimpse of the “dancing dolphins’ aqueous ballet.” These evocative expressions invite you to craft narratives that rival those crafted by Homer himself!

5) A Flotilla United by Secret Code: Picture yourself amidst a fleet regatta, surrounded by fellow sailors all fluent in this secret maritime lexicon. This peculiar linguistic bond establishes instant connections beyond conventional exchanges shared in mainstream society. An initiation into sailing terminologies is akin to unlocking a secret code, granting you access to new friendships built on shared experiences and mutual appreciation for life’s most elemental forces: wind, water, and adventure.

Conclusion: As we conclude our journey through the oceanic tapestry woven by nautical terms and phrases, it becomes evident that their power extends far beyond mere communication. Sailing lingo elevates your voyage from practicality to poetry, endowing each moment on deck with historical significance and artistic resonance. By embracing these traditions and enriching your sailing vernacular with colorful expression, you become part of a timeless legacy that has inspired dreamers and adventurers throughout centuries. So let us hoist our sails high while whispering tales told countless times before – may our newfound command over nautical terminology enhance our quest for freedom on the open seas!

Frequently Asked Questions about Sailing Terms and Phrases Answered

Sailing is a unique and exciting experience that brings together the beauty of nature and the thrill of adventure. Whether you are an experienced sailor or a novice looking to learn more about this captivating activity, it’s important to understand the various sailing terms and phrases that are commonly used in the sailing community. To help you navigate through these sometimes confusing waters, we have put together a list of frequently asked questions answered with detailed professional explanations, sprinkled with witty and clever anecdotes. So sit back, relax, and let’s dive into the world of sailing terminology!

Q1: What exactly is a “jib”?

A1: Ah, the jib! This term refers to a triangular sail located at the front of the boat, usually attached to the forestay (the wire that holds up the mast). The jib serves as one of the primary sources of propulsion for sailing vessels. Think of it as the boat’s secret weapon – it catches wind and propels your vessel forward! Just like a jester adding an element of surprise in medieval courts.

Q2: Can you explain what “tacking” means?

A2: Tacking is perhaps one of the most fundamental maneuvers in sailing. It involves turning your boat into or across the wind so that your sails switch sides. Picture yourself maneuvering your way through rush hour traffic – except instead of cars, there are waves crashing against each other! Tacking allows sailors to make headway against windward, zigzagging their way to their destination like Shakespearean characters in a fiery debate.

Q3: I’ve heard people talk about “heeling.” What does it mean?

A3: Ahoy there! Heeling refers to when a sailboat leans over sideways due to strong winds pushing against its sails. This ‘Michael Jackson-esque’ dance move can be quite exhilarating for thrill-seekers, but it requires careful balance and control. Imagine holding a delicate ballet pose on a tilting stage while attempting to impress the judges. That’s what heeling is all about – finding the perfect equilibrium between adventure and stability.

Q4: What is meant by “mainsail”?

A4: The mainsail is the largest and most visible sail on a sailing vessel. It is typically attached to the mast and plays a crucial role in powering the boat forward when the wind hits it just right. This sail can be compared to the lead vocalist of a band – it takes center stage and commands attention, providing maximum power to propel your floating oasis across the water.

Q5: Can you explain what “port” and “starboard” mean?

A5: Ahoy, matey! Port refers to the left side of a boat when facing its bow (front), while starboard refers to its right side. Now, how do you remember which is which? Here’s a clever trick: port has four letters, just like LEFT, so it’s easy to associate them together. And starboard has more letters than port or left, so that must be RIGHT! Remember this little rhyme, and you’ll never steer your ship in the wrong direction again.

So there you have it – some frequently asked questions about sailing terms and phrases answered with detailed professional insight mixed with witty and clever comparisons. We hope this helps unravel some of the mysteries behind those nautical expressions that sailors throw around with ease. Happy sailing!

Mastering the Jargon: Unraveling the Language of Sailing

Sailing, with its long and storied history, offers enthusiasts an escape into a world rich in tradition and adventure. From battling treacherous waves to navigating the vast expanses of the open sea, sailors are no strangers to challenges. However, there is one aspect of sailing that can often leave beginners feeling adrift – the intricate and sometimes befuddling language used in this esteemed practice.

In this blog post, we aim to demystify the jargon of sailing, allowing novices to navigate conversations with seasoned sailors and ultimately feel more at home on deck.

Tacking and Jibing – Oh My!

One of the most fundamental concepts in sailing revolves around changing direction – but don’t call it turning! Sailors use specific terms like tacking and jibing to describe these maneuvers. Tacking involves turning into the wind by steering through a series of tight angles, while jibing entails turning away from the wind in a more fluid motion. So if you hear someone say “Prepare to tack!” or “Jibe ho!”, now you’ll know what they mean.

Hoist That Main Sail!

As you familiarize yourself with sailboats, you’ll swiftly encounter talk about different sails – mainsails being one of them. The mainsail is crucial for propelling your vessel forward and adjusting its position relative to the wind. When you hear someone shout “Hoist that main!” they’re simply telling their crewmates to raise or unfurl this essential sail. Remember, timing is key when hoisting your main as it affects your boat’s performance and maneuverability.

Trimming Your Sails

Ever wondered what sailors mean by “trimming” their sails? No, they’re not talking about giving them a haircut! Trimming refers to adjusting your sails’ position relative to the wind for optimal efficiency – something akin to finetuning your instrument. By playing with the sheets (lines that control sail shape), sailors can harness the wind’s power effectively, propelling themselves along smoothly and efficiently.

The Wind Angle – A Sailor’s Best Friend

Understanding wind angles is paramount for any sailor worth their salt. When sailors refer to “the point of sail,” they are describing the direction they are sailing relative to the wind. Different points of sail include close-hauled (sailing as close to the wind as possible) and running (sailing in the same direction as the wind). Knowledge of these angles determines how a skilled sailor adjusts their sails, achieving optimal speed and stability.

Raising Anchor – Setting Sail!

Embarking on a sailing adventure often begins with raising anchor or setting sail. However, it’s not just about hoisting a heavy object; there is an art to it! The crew works together seamlessly, making sure the anchor is secured safely before preparing to lift it from its watery resting place. With a well-coordinated effort, they can free themselves from shore and set out into open waters to seek out new horizons.

Navigating Lingo Land

As you delve deeper into sailing culture, you’ll soon notice a myriad of unique terms specific to this maritime world – jargon like ‘batten down the hatches,’ ‘hard-a-lee,’ or ‘full-and-by.’ Each phrase has its own charm and colorful history that adds character and camaraderie amongst sailors. Embrace this lexicon with enthusiasm, for it symbolizes connection with centuries-old traditions and ensures clear communication at sea.

So whether you decide to hoist your sails under clear blue skies or undertake epic adventures across stormy seas, mastering the jargon of sailing will undoubtedly enhance your experience. Armed with this newfound knowledge, you’ll be able to hold engaging conversations with fellow sailors while feeling like an old salty sea dog yourself. Fair winds ahead!

Are you ready to elevate your boating skills and impress everyone on board with your extensive knowledge of sailing terms and phrases? Look no further, as we’re here to help you take your boating game up a notch!

Sailing has its own unique language that can initially seem daunting to beginners. However, mastering these essential sailing terms and phrases not only enhances your understanding of the sport but also ensures seamless communication with fellow sailors. So let’s dive into this linguistic adventure and emerge as refined seafarers!

1. Bow: This term refers to the front part of the boat. Imagine standing at the bow, with the wind blowing through your hair, as you confidently navigate through the open waters.

2. Stern: The opposite of the bow, the stern is the back end of the vessel. Picture yourself lounging on the stern while basking in the sun, enjoying a leisurely day on your boat.

3. Port: When facing forward towards the bow, port refers to the left side of a boat or yacht. Remember it by associating “port” with “left,” both consisting of four letters.

4. Starboard: In contrast to port, starboard indicates the right side of a boat when facing forward. An easy way to remember is by imagining a bright star guiding you towards success.

5. Tacking: To change direction against or across the wind using sails is known as tacking. It involves turning or pivoting through head-to-wind coordination, allowing your boat to zigzag efficiently while harnessing variable wind angles.

6. Jib: A triangular sail positioned in front of a mast is called a jib and primarily aids in steering when sailing close-hauled or reaching conditions.

7. Mainsail: The largest sail on most boats, attached vertically along a mast toward aft (near stern) direction commands utmost respect – it’s called a mainsail! Mastering control over the mainsail is essential for maximizing speed and maneuverability.

8. Windward: The direction from which the wind is coming is referred to as windward. Sailing toward the windward side can be challenging yet exhilarating, requiring precise navigation techniques for optimal performance.

9. Leeward: The opposite of windward, leeward denotes the side away from the wind or downwind direction. When sailing on the leeward side, you’ll experience smoother conditions with less turbulence — a perfect opportunity for relaxation and enjoying your boating adventure.

10. Rudder: Acting as a ship’s steering mechanism, the rudder controls its movement by changing its course in response to the helmsperson’s commands. Mastering rudder control ensures smooth sailing and accurate navigation.

Now armed with these essential sailing terms and phrases, you can confidently navigate through any boating expedition while impressing your friends with your newfound knowledge! So hoist those sails, trim them accurately, and let these words navigate you towards becoming an impeccable sailor. Fair winds and following seas await you on this exciting journey!

Sailing Terms Demystified: A Comprehensive Guide to 14 Common Sailing Terminology

• May 28, 2023

Ahoy, sailors! If you’re new to the world of sailing, you might find yourself overwhelmed by the myriad of sailing terms that seasoned sailors casually toss around. But fear not! In this comprehensive guide, we’ll unravel the mystery behind common sailing terms, providing simple explanations and examples to help you navigate the nautical jargon with ease. Let’s set sail and explore these essential sailing terms.

Table of Contents

Port and starboard.

When on a boat, “port” refers to the left side, while “starboard” refers to the right side. These terms are used to communicate directions and indicate the location of objects or maneuvers. For example, “Please pass me the fenders on the starboard side.”

Bow and Stern

The “bow” refers to the front or forward part of a boat, while the “stern” refers to the back or rear part.

Windward and Leeward

“Windward” refers to the side of the boat or the direction from which the wind is coming. On the other hand, “leeward” refers to the opposite side, sheltered from the wind. Sailors use these terms to plan their course and make tactical decisions.

Tacking and Jibing

“Tacking” is the act of turning the bow of the boat through the wind, changing the side from which the wind is coming. This allows the boat to change direction while sailing upwind. “Jibing” is the opposite maneuver, turning the stern of the boat through the wind to change direction when sailing downwind.

“Rigging” refers to the system of ropes, wires, and other components used to support and control the sails and mast. It includes various elements such as halyards (ropes used to hoist the sails), sheets (ropes used to control the angle of the sails), and shrouds (wires supporting the mast).

“Heeling” describes the leaning or tilting of a sailboat due to the force of the wind on the sails. The boat can lean to one side, causing it to tilt and creating a thrilling sensation. Sailors adjust the sails and shift their weight to maintain balance and control.

“Reefing” is the process of reducing the area of a sail to decrease its surface area and power in strong winds. This is done by partially lowering or folding a section of the sail and securing it, thus making the sail smaller and more manageable.

The “keel” is the central structural element of a sailboat, usually made of heavy material such as lead or iron. It extends beneath the boat into the water and provides stability and prevents the boat from sliding sideways.

Navigational Markers

Navigational markers, also known as buoys, are floating objects that indicate safe passages, hazards, or important locations in the water. They are color-coded and labelled according to their purpose. For instance, a red buoy with even numbers indicates the right side of a channel when entering from the sea.

Points of Sail

Sailboats have different angles at which they can sail relative to the direction of the wind, which are called “points of sail.” The main points of sail include close-hauled (sailing as close to the wind as possible), reaching (sailing at an angle between close-hauled and a broad reach), and running (sailing with the wind directly behind).

By familiarizing yourself with these essential sailing terms, you’ll be able to communicate effectively, understand instructions, and navigate the sailing world with confidence. So hoist your sails, embrace the wind, and embark on unforgettable nautical adventures armed with the knowledge of sailing terminology. Fair winds and smooth seas!

Parts of a Sailboat

Before you can begin your sailing adventure, it’s important to familiarize yourself with the different parts of a sailboat. From the sleek bow to the sturdy keel, each component plays a vital role in keeping your vessel afloat and propelling you forward through the waves.

• Hull The main body of the boat that sits in the water and provides buoyancy and stability.
• Bow The front of the boat that meets the water and helps to determine its direction.
• Stern The rear of the boat where the rudder and motor are located.
• Deck The flat surface of the boat that you stand on, which can include various features such as seating, storage compartments, and hatches.
• Cockpit The recessed area of the deck where the skipper and crew sit or stand while sailing, which allows for easy access to the sail controls and provides protection from the wind and waves.
• Keel The long, fin-shaped structure beneath the waterline that helps to keep the boat stable and upright.
• Rudder The flat, vertical surface located at the stern of the boat that is used to steer and control the direction of the boat.
• Tiller or wheel The mechanism used to steer the boat, either in the form of a tiller (a handle attached to the rudder) or a wheel (similar to the steering wheel of a car).
• Mast The tall, vertical pole that supports the sails and allows you to catch the wind and move through the water.
• Boom The horizontal pole extending off the bottom of the mast that holds the bottom edge of the mainsail.
• Mainsail The large, triangular-shaped sail attached to the mast and boom that captures the wind’s power to propel the boat forward.
• Jib The smaller, triangular-shaped sail attached to the bow that helps to steer the boat and balance the force of the mainsail.
• Rigging The network of ropes and cables that hold the mast and sails in place and help control their movement.

Sail Terminology

Understanding the terminology associated with sails is critical to becoming a successful sailor. Here are 12 of the most important sail terms you should know, along with brief explanations for each:

• Luff The forward edge of a sail that is attached to the mast, allowing you to adjust the sail’s shape and angle to catch more wind.
• Leech The aft edge of a sail that is attached to the boom, which helps to control the sail’s shape and release the wind as needed.
• Foot The lower edge of a sail that is attached to the boom, which helps to control the sail’s shape and power.
• Head The top of a sail that is attached to the mast and controls the sail’s overall shape and angle.
• Battens The long, thin strips inserted into the pockets of a sail to help maintain its shape and stiffness.
• Clew The bottom corner of a sail that is attached to the boom or sheet, which helps to control the sail’s shape and power.
• Tack The bottom forward corner of a sail that is attached to the boat or a line, which helps to control the sail’s shape and power.
• Sail Area The total area of a sail, which is measured in square feet or meters.
• Sail Draft The curve or depth of a sail, which affects its performance and power.
• Sail Shape The overall form and contour of a sail, which is critical for catching the wind effectively.
• Reefing The process of reducing the sail area by partially lowering or folding the sail, which can be necessary in strong winds or heavy seas.
• Furling The process of rolling or folding a sail to reduce its size or stow it away, which is often used when entering or leaving port or in rough conditions.

Wind Direction and Sail Positioning

Understanding wind direction and sail positioning is crucial for successful sailing. Here are the key terms you need to know:

Types of Wind

• Apparent Wind The wind that is felt on the boat, which is a combination of the true wind and the wind generated by the boat’s movement.
• True Wind The actual direction and strength of the wind.

Points of Sail

You can find a detailed explanation of the points of sail here

• Close-Hauled Sailing as close to the wind as possible, with the sail set at a sharp angle to the boat.
• Beam Reach Sailing perpendicular to the wind, with the sail set at a right angle to the boat.
• Broad Reach Sailing with the wind at a diagonal angle behind the boat, with the sail angled away from the boat.
• Running Sailing directly downwind, with the sail on one side of the boat.

Other Terms

• Windward The side of the boat that is facing the wind.
• Leeward The side of the boat that is sheltered from the wind.
• Sail Trim Adjusting the sail and rigging to maximize the power and efficiency of the sailboat.

Navigation Terminology

Navigating a sailboat requires an understanding of a variety of nautical terms. Here are some of the most important terms you should know:

• Starboard Side The right side of a boat
• Port Side The left side of a boat
• Compass A device used for determining the boat’s heading or direction.
• Bearing The direction from the boat to a specific point on land or water.
• Chart A map or nautical publication that displays water depths, navigational aids, and other important information for safe navigation.
• Latitude The angular distance between the equator and a point on the earth’s surface, measured in degrees, minutes, and seconds.
• Longitude The angular distance between the prime meridian and a point on the earth’s surface, measured in degrees, minutes, and seconds.
• Course The direction in which the boat is traveling.
• Plotting The process of marking a course on a chart or map.
• Waypoint A specific point on a navigational chart or map that serves as a reference point for plotting a course.

• Tacking This maneuver involves turning the bow of the boat through the wind in order to change direction. To tack , the sailor will turn the helm towards the wind until the sails begin to luff, then quickly steer the boat in the opposite direction while adjusting the sails to catch the wind on the new tack.
• Jibing This maneuver is similar to tacking, but involves turning the stern of the boat through the wind. To jibe, the sailor will steer the boat downwind until the sails begin to luff, then quickly turn the stern of the boat in the opposite direction while adjusting the sails to catch the wind on the new tack.
• Heading up This maneuver involves turning the boat closer to the wind in order to sail upwind. To head up, the sailor will turn the helm towards the wind while simultaneously trimming the sails in to maintain speed and prevent the boat from stalling.
• Falling off This maneuver involves turning the boat away from the wind in order to sail downwind. To fall off, the sailor will steer the helm away from the wind while simultaneously easing the sails out to catch more wind and accelerate the boat.
• Docking This maneuver involves bringing the boat alongside a dock or other fixed object in order to moor or disembark. To dock, the sailor will typically approach the dock at a slow speed while using lines and fenders to control the boat’s position and prevent damage.

Knots and Lines

Learning the right knots and lines to use is essential for any sailor. Here are some of the most important knots and lines to know:

• Bowline This is a versatile knot used for many purposes, including attaching a line to a fixed object, such as a mooring or cleat.
• Square Knot A simple knot used to join two lines of the same diameter.
• Clove Hitch A quick and easy knot for attaching a line to a post or piling.
• Figure-Eight Knot A knot used to stop the end of a line from unraveling.
• Cleat Hitch A knot used to secure a line to a cleat.
• Sheet Bend A knot used to join two lines of different diameters.

• Main Halyard A line used to raise the mainsail.
• Jib Sheet A line used to control the angle of the jib.
• Mainsheet A line used to control the angle of the mainsail.
• Jib Furling Line A line used to furl the jib.

Sailing Safety

• Personal Flotation Devices (PFDs) These are the life jackets or vests that you must wear when on board to ensure your safety. Choose a PFD that fits you properly and is appropriate for your body weight.
• Tethers and Harnesses These are designed to keep you attached to the boat and prevent you from falling overboard. Make sure to clip yourself onto the boat when you’re on deck or going up to the mast.
• Man Overboard ( MOB ) Drill This is a critical safety procedure to practice with your crew. Learn how to quickly identify and recover someone who has fallen overboard.
• Emergency Position Indicating Radio Beacon (EPIRB) An EPIRB sends a distress signal and your location to rescue services in an emergency. Make sure it’s properly registered and in good working condition.
• Navigational Lights Ensure your boat has the required navigational lights and know how to use them properly. These lights help other boats see you in low-light conditions.

Remember that safety is always the top priority when sailing, and it’s essential to take it seriously.

Sailing Terminology Conclusion

As we come to the end of our sailing terminology crash course, it’s important to remember that the world of sailing is vast and varied. Learning even the basics can be a daunting task, but with practice and perseverance, you’ll be able to hoist your sails and set a course for adventure.

Whether you’re a seasoned sailor or just starting out, understanding the terminology is crucial to ensure a safe and enjoyable voyage. From the parts of the boat to the knots and lines, each aspect plays a significant role in the overall sailing experience.

What is the difference between apparent wind and true wind?

Apparent wind is the wind felt by the sailor on the boat, while true wind is the wind direction and speed relative to the ground.

What are the points of sail?

The points of sail are the directions that a sailboat can travel in relation to the wind. They include upwind, close-hauled, beam reach, broad reach, and downwind.

What does it mean to be “on a reach”?

Being “on a reach” means sailing with the wind coming from the side of the boat, at a perpendicular angle to the boat’s direction.

What is tacking?

Tacking is the maneuver used to turn the boat’s bow through the wind, allowing the boat to change direction while still sailing upwind.

What is jibing?

Jibing is the maneuver used to turn the boat’s stern through the wind, allowing the boat to change direction while sailing downwind.

What is the difference between windward and leeward?

Windward is the side of the boat that is facing into the wind, while leeward is the side of the boat that is sheltered from the wind.

What is a boom vang?

A boom vang is a line used to control the position of the boom, which helps control the shape and position of the sail.

What is a cleat?

A cleat is a device used to secure a line to the boat, allowing the sailor to adjust the tension of the line without having to hold onto it constantly.

What is a winch?

A winch is a mechanical device used to control lines and adjust sails. It typically consists of a drum and handle that can be turned to wind or unwind a line.

17 Sailboat Types Explained: How To Recognize Them

Ever wondered what type of sailboat you're looking at? Identifying sailboats isn't hard, you just have to know what to look for. In this article, I'll help you.

Every time I'm around a large number of sailboats, I look around in awe (especially with the bigger ones). I recognize some, but with most of them, I'll have to ask the owner. When they answer, I try to hide my ignorance. The words don't make any sense!

So here's a complete list with pictures of the most common sailboat types today. For each of them, I'll explain exactly where the name comes from, and how you can recognize it easily.

So here's my list of popular sailboat types, explained:

Bermuda sloop, sailing hydrofoil, dutch barge, chinese junk, square-rigged tall ship, in conclusion, how to recognize any sailboat.

Before we get started, I wanted to quickly explain what you should look for when you try to identify a sailboat.

The type of sailboat is always determined by one of these four things:

• The type of hull
• The type of keel
• The number of masts
• And the type of sails and rig

The hull is the boat's body. There are basically three hull types: monohull, catamaran, and trimaran. Simply said: do I see one hull, two hulls (catamaran) or three hulls (trimaran)? Most sailboats are monohulls.

Next, there is the keel type. The keel is the underwater part of the hull. Mostly, you won't be able to see that, because it's underwater. So we'll leave that for now.

The sail plan

The last factor is the number of masts and the sail plan. The sail plan, simply put, is the number of sails, the type of sails, and how the sails are mounted to the masts (also called rigging ).

Sailboat are mostly named after the sail plan, but occasionally, a sail type is thrown in there as well.

So now we know what to pay attention to, let's go and check out some sailboats!

Dinghies are the smallest and most simple sailboats around.

They are your typical training sailboats. Small boats with an open hull, with just one mast and one sail. Perfect for learning the ways of the wind.

On average, they are between 6 and 20 ft long. Mostly sailed single-handed (solo). There's no special rigging, just the mainsail. The mainsail is commonly a Bermuda (triangular) mainsail. Dinghies have a simple rudder stick and no special equipment or rigging.

Dinghies are great for learning how to sail. The smaller the boat, the better you feel the impact of your trim and actions.

How to recognize a sailing dinghy:

• short (8ft)
• one Bermuda sail
• open hull design
• rudder stick

Common places to spot them: lakes, near docks

If you'd ask a kid to draw a sailboat, she'll most probably draw this one. The Bermuda Sloop is the most popular and most common sailboat type today. You'll definitely recognize this one.

How to recognize a Bermuda Sloop:

• triangular mainsail (called a Bermuda sail)
• a foresail (also called the jib)
• fore-and-aft rigged
• medium-sized (12 - 50 ft)

Fore-and-aft rigged just means "from front to back". This type of rigging helps to sail upwind.

Any sailboat with one mast and two sails could still be a sloop. Even if the sails are another shape or rigged in another way. For example, here's a gaff-rigged sloop (more on the gaff rig later):

If you want to learn all about sail rigs, check out my full Guide to Understanding Sail Rig Types here. It has good infographics and explains it in more detail

The Bermuda sloop has a lot of advantages over other sailboat types (which is why it's so popular):

• the Bermuda rig is very maneuverable and pretty fast in almost all conditions
• it's really versatile
• you can sail it by yourself without any problems
• it's a simple setup

Common places to spot a sloop: everywhere. Smaller sloops are more common for inland waters, rivers, and lakes. Medium-sized and large sloops are very popular cruising boats.

Cutters have one mast but three or more sails. Most cutters are Bermuda rigged, which means they look a lot like sloops.

How to recognize a cutter:

• looks like a sloop
• two or more headsails instead of one
• commonly one mast
• sometimes an extra mast with mainsail

Cutters have more sail area, which makes them faster, but also harder to sail single-handed. There's also more strain on the mast and rigging.

Common places to spot a cutter: everywhere. Cutters are very popular for cruising.

They mostly have a Bermuda rig, which means triangular sails. But there are also gaff cutters and naval cutters, and some have two masts.

Here's an example of a two-masted naval cutter with an extra gaff mainsail and top gaff:

The Hydrofoil is a pretty new sailboat design. It's a racing sailboat with thin wing foils under the hull. These lift up the hull, out of the water, reducing the displacement to nearly zero. The foils create downforce and keep it from lifting off entirely.

This makes the hydrofoil extremely fast and also impressive.

The hydrofoil refers to the keel type. There are both monohull and multihull hydrofoils.

How to recognize a hydrofoil:

• it flies above the waterline and has small fins

Common places to spot a hydrofoil: at racing events

Famous catamaran: La Vagabonde from Sailing La Vagabonde

A catamaran is a type of cruising and racing multihull sailboat with two hulls. The hulls are always the same size.

Most catamarans have a standard Bermuda rig. The catamaran refers to the hull, so it can have any number of masts, sails, sail types and rig type.

How to recognize a catamaran:

• any boat with two hulls is called a catamaran

Common places to spot catamarans: coastal waters, The Caribbean, shallow reefs

The advantages of a catamaran: Catamarans heel less than monohulls and are more buoyant. Because of the double hull, they don't need as deep a keel to be stable. They have a smaller displacement, making them faster. They also have a very shallow draft. That's why catamarans are so popular in the Caribbean, where there's lots of shallow water.

Catamarans are nearly impossible to capsize:

"Compared with a monohull, a cruising catamaran sailboat has a high initial resistance to heeling and capsize—a fifty-footer requires four times the force to initiate a capsize than an equivalent monohull." Source: Wikipedia

How to recognize a trimaran:

• any boat with three hulls is called a trimaran

Trimarans have three hulls, so it's a multi-hull design. It's mostly a regular monohull with two smaller hulls or floaters on the sides. Some trimarans can be trailered by winching in the auxiliary hulls, like this:

This makes them very suitable for long-term cruising, but also for regular docking. This is great for crowded areas and small berths, like in the Mediterranean. It sure is more cost-effective than the catamaran (but you also don't have the extra storage and living space!).

Common places to spot Trimarans: mostly popular for long-term cruising, you'll find the trimaran in coastal areas.

Gaffer refers to gaff-rigged, which is the way the sails are rigged. A gaff rig is a rectangular sail with a top pole, or 'spar', which attaches it to the mast. This pole is called the 'gaff'. To hoist the mainsail, you hoist this top spar with a separate halyard. Most gaffers carry additional gaff topsails as well.

Gaff rigs are a bit less versatile than sloops. Because of the gaff, they can have a larger sail area. So they will perform better with downwind points of sail. Upwind, however, they handle less well.

How to recognize a gaffer:

• sail is rectangular
• mainsail has a top pole (or spar)

Since a gaffer refers to the rig type, and not the mast configuration or keel type, all sailboats with this kind of rigging can be called 'gaffers'.

Common places to spot a gaffer: Gaffers are popular inland sailboats. It's a more traditional rig, being used recreationally.

Schooners used to be extremely popular before sloops took over. Schooners are easy to sail but slower than sloops. They handle better than sloops in all comfortable (cruising) points of sail, except for upwind.

How to recognize a schooner:

• mostly two masts
• smaller mast in front
• taller mast in the back
• fore-and-aft rigged sails
• gaff-rigged mainsails (spar on top of the sail)

Common places to spot a schooner: coastal marinas, bays

How to recognize a ketch:

• medium-sized (30 ft and up)
• smaller mast in back
• taller mast in front
• both masts have a mainsail

The ketch refers to the sail plan (mast configuration and type of rig). Ketches actually handle really well. The back mast (mizzenmast) powers the hull, giving the skipper more control. Because of the extra mainsail, the ketch has shorter masts. This means less stress on masts and rigging, and less heel.

Common places to spot a ketch: larger marinas, coastal regions

How to recognize a yawl:

• main mast in front
• much smaller mast in the back
• back mast doesn't carry a mainsail

The aft mast is called a mizzenmast. Most ketches are gaff-rigged, so they have a spar at the top of the sail. They sometimes carry gaff topsails. They are harder to sail than sloops.

The yawl refers to the sail plan (mast configuration and type of rig).

Common places to spot a yawl: they are not as popular as sloops, and most yawls are vintage sailboat models. You'll find most being used as daysailers on lakes and in bays.

Dutch Barges are very traditional cargo ships for inland waters. My hometown is literally littered with a very well-known type of barge, the Skutsje. This is a Frisian design with leeboards.

Skutsjes don't have a keel but use leeboards for stability instead, which are the 'swords' or boards on the side of the hull.

How to recognize a Dutch Barge:

• most barges have one or two masts
• large, wooden masts
• leeboards (wooden wings on the side of the hull)
• mostly gaff-rigged sails (pole on top of the sail, attached to mast)
• a ducktail transom

The clipper is one of the latest sailboat designs before steam-powered vessels took over. The cutter has a large cargo area for transporting cargo. But they also needed to be fast to compete with steam vessels. It's a large, yet surprisingly fast sailboat model, and is known for its good handling.

This made them good for trade, especially transporting valuable goods like tea or spices.

How to recognize a Clipper:

• mostly three masts
• square-rigged sails
• narrow but long, steel hull

Common places to spot a clipper: inland waters, used as houseboats, but coastal waters as well. There are a lot of clippers on the Frisian Lakes and Waddenzee in The Netherlands (where I live).

This particular junk is Satu, from the Chesapeake Bay Area.

The Chinese Junk is an ancient type of sailboat. Junks were used to sail to Indonesia and India from the start of the Middle Ages onward (500 AD). The word junk supposedly comes from the Chinese word 'jung', meaning 'floating house'.

How to recognize a Chinese junk:

• medium-sized (30 - 50 ft)
• large, flat sails with full-length battens
• stern (back of the hull) opens up in a high deck
• mostly two masts (sometimes one)
• with two mainsails, sails are traditionally maroon
• lug-rigged sails

The junk has a large sail area. The full-length battens make sure the sails stay flat. It's one of the flattest sails around, which makes it good for downwind courses. This also comes at a cost: the junk doesn't sail as well upwind.

The cat rig is a sail plan with most commonly just one mast and one sail, the mainsail.

Most sailing dinghies are cats, but there are also larger boats with this type of sail plan. The picture above is a great example.

How to recognize a cat rig:

• smaller boats
• mostly one mast
• one sail per mast
• no standing rigging

Cat-rigged refers to the rigging, not the mast configuration or sail type. So you can have cats with a Bermuda sail (called a Bermuda Cat) or gaff-rigged sail (called a Gaff Cat), and so on. There are also Cat Ketches and Cat Schooners, for example. These have two masts.

The important thing to know is: cats have one sail per mast and no standing rigging .

Most typical place to spot Cats: lakes and inland waters

Famous brig: HMS Beagle (Charles Darwin's ship)

A brig was a very popular type of small warship of the U.S. navy during the 19th century. They were used in the American Revolution and other wars with the United Kingdom. They carry 10-18 guns and are relatively fast and maneuverable. They required less crew than a square-rigged ship.

How to recognize a brig:

• square-rigged foremast
• mainmast square-rigged or square-rigged and gaff-rigged

How to recognize a tall ship:

• three or four masts
• square sails with a pole across the top
• multiple square sails on each mast
• a lot of lines and rigging

Square-rigged ships, or tall ships, are what we think of when we think of pirate ships. Now, most pirate ships weren't actually tall ships, but they come from around the same period. They used to be built from wood, but more modern tall ships are nearly always steel.

Tall ships have three or four masts and square sails which are square-rigged. That means they are attached to the masts with yards.

We have the tall ship races every four years, where dozens of tall ships meet and race just offshore.

Most common place to spot Tall Ships: Museums, special events, open ocean

This is a bonus type since it is not very common anymore. As far as I know, there's only one left.

The Trabaccolo is a small cargo ship used in the Adriatic Sea. It has lug sails. A lug rig is a rectangular sail, but on a long pole or yard that runs fore-and-aft. It was a popular Venetian sailboat used for trade.

The name comes from the Italian word trabacca , which means tent, referring to the sails.

How to recognize a Trabaccolo:

• wide and short hull
• sails look like a tent

Most common place to spot Trabaccolo's: the Marine Museum of Cesenatico has a fully restored Trabaccolo.

So, there you have it. Now you know what to look for, and how to recognize the most common sailboat types easily. Next time you encounter a magnificent sailboat, you'll know what it's called - or where to find out quickly.
