Searail 19 is a 19 ′ 0 ″ / 5.8 m trimaran sailboat designed by Nigel Irens and built by /Phil Medley starting in 2012.

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

• SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
• D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

• D: Displacement of the boat in pounds
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

Beam folded: 1.8m/6.92’ opt. Furling Spinnaker: 25.83 m2/278 sq.ft. Main: 16m2/176sq.ft. R/F jib: 7.7m2/83sq.ft. Spinnaker: 22m2//278sq.ft. Mast length: 9.12m/29.83’

Your Source for Multihull Fun!

The Multihull Source has been serving up exciting sailing for nearly 30 years. The company has evolved along with the designs and technology of the multihull sailing world. Bob and Ira are dealers for not only the latest and most important boat lines in the industry, but the experience to help sailors get exactly the right boat for them.

At Seawind catamarans we are regularly asked “Convince me why I should buy a catamaran instead of a monohull”. Like everything, there are pluses and there are minuses and we try to give the person a balanced answer. Of course the pluses and minuses are more or less compelling for different people depending on their circumstances and their sailing ambitions. However, a growing number of people are coming down heavily one side and becoming firm catamaran converts.

Corsair Trimarans are versatile, exciting and offer superb performance for racing and cruising with the family. They also feature unique trailerability (trailer to sailing in 30 minutes), shallow draft and uncompromised comfort and safety. All of The Multihull Source team members own and race Corsair trimarans - no other dealer can offer more knowledge about all the different models.

Trimarans are fun because they enable you to discover places that others cannot venture to. The draft of the Rapido 60 is only 0.75m when the rudder blade and dagger board are retracted, which facilitates shallow water navigation and anchorage. Comfortable nets 6.3m x 3m on both sides of the Rapido 60 provide an enormous space to play or lounge when the fish are not biting.

Morrelli & Melvin have designed Gunboat luxury sailing catamarans blending racing performance with the finest level of comfort and amenities.

Morrelli & Melvin has a fantastic track record of designing creative, sound, safe, energy efficient, fun and fast multihulls and monohulls and we go the extra distance to ensure that they get built to our specifications.

The new Nigel Iren's design SeaRail 19 has arrived in North America!

The SR-19 is an exciting, affordable, light-weight, trailerable trimaran built to cater to a wide rangel of sailors. Whether it's day saling with your family, resort sailing or camper sailing, the SeaRail 19 is an ideal leisure trimaran.

The WETA trimaran is a great performing 4.4 m or 14'5" triamaran. Only a WETA can be sailed with one, two or three sails blazing by one, two or three people!

No wonder it was Boat of the Year in 2010!

Composite foam sandwich hulls with Carbon spars and beams make this little trimaran as robust as it is versatile. A trimarans legendary forgiving nature means that anyone can jump on the Weta and immediately feel confident.

The Multihull Source was formed in 1995 when Bob Gleason teamed up with Bert Kornyei to expand his Corsair dealership into other multihulls. Bert had recently bought his first Corsair from Bob and was excited to start this new venture.

The next Trimaran Sailing Clinic hosted by Windcraft will be at the Fort Walton Yacht Club in the Florida Panhandle May 5-7, 2017. However we are completely fully booked up for that clinic. The next one with spaces available will be the weekend of October 14-15. In our clinics 16 students will see their sailing skills improve dramatically over the two days of the course which is taught by world class multihull sailor and coach Randy Smyth. Students of all levels are introduced to Randy’s highly effective techniques for optimizing sail trim, and learn how best to hoist, jibe and douse a spinnaker, as well as how to tack a screacher upwind. Call or email us  for more information.
