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)

Let's Get to Know Each Other

Let's connect, precision 21 sailboat.

The P21 is an outstanding design produced by the accredited boat designer, Jim Taylor. Before designing this model, he had worked on six similar sailboats (P15, P15K, P165, P18, P185, and P185K.) The Precision 21 was built by the Precision Boat Works in the United States.

It has a practical keel and centerboard combination; its NACA wing section can be used in numerous ways: it can be extended, pulled downward, or left in the middle. Moreover, it has a stellar sail area of 203 sq. ft. that offers minimal effort to get the boat moving in light air.

Looking at its design, the model has an overall length of 20’ 90”. It is not only relatively larger than the previous sailing boats, but it also offers a higher performance as it runs on a 600 lb. ballast keel. It is designed with a 7’ 1” self-bailing cockpit and a fiberglass deck. The deck is furnished with berths, storage shelves, lockers, interior lights, deluxe fabric covered cushions, and an alcohol stove. It is also engineered with a self-contained fresh water pump and stainless-steel sink.

This sailing boat is ideal for small families as it easily accommodates four average-size adults.

Precision 21' - self righting ?

• Thread starter Bluenoser
• Start date Aug 9, 2020
• Brand-Specific Forums

Purchased a 98 Precision 21' and having lots of fun but am a little concerned about what might happen if I get heeled over a little too far in a good wind gust. Grandkids just like to hang out in the cabin, so I'm thinking maybe they shouldn't be in there in strong winds. Any comments are greatly appreciated.  

It will round up into the wind assuming you are over canvased, nobody will be happy and people could get hurt being thrown from one side to the other. I would not sail in sporty conditions first with small kids, and I would already have my main reefed and keep a hand on the travler line.  

How much can I push a precision 21?
