Sailing Ratios

Classic yacht-design ratios worked out from the builder's published figures, each shown against the bands designers read it by.

Sail area / displacement

How much sail the boat carries for its weight — its power in light air.

  • not published: sail area
How it is worked out

sail area (ft²) ÷ (displacement as ft³ of seawater)^⅔

Displacement / length

How heavy the boat is for its waterline length. Lower is lighter and quicker; higher is steadier and roomier.

How it is worked out

displacement (long tons) ÷ (0.01 × waterline length in ft)³

Most builders publish a light displacement. The ratios were defined on a loaded boat, so every boat here reads a little lighter than a surveyor's figure would — all alike, which keeps them comparable.

Tanks

What the builder publishes about how fast, how strong and how much the boat carries.

Fuel and water on one scale: a tank twice the height holds twice as much.

Design limits set by the EU Recreational Craft Directive (2013/53/EU), in significant wave height. A category covers the conditions of those below it. It is the limit the boat was designed to, not a promise that it is safe in any conditions within it — that judgement stays with the skipper.

About Rapido Trimarans

Premium production

Carbon performance trimarans designed by Morrelli & Melvin and built in Vietnam by Triac Composites, the yard co-founder Paul Koch set up in 2014 — the folding Rapido 40 and 50, the 53XS, the Rapido 60 and 63, a 40 Racer and the R500 ECO Power Cat.

Rapido, in the company's telling, began with a simple idea: there should be a better way to cross an ocean under sail. Co-founder Paul Koch had spent his life designing, building and sailing multihulls — he started in 1986 with OSTAC Yachts (Ocean Sailing Trimarans and Catamarans) and from 1994 to 2010 led Corsair Marine, helping turn the trimaran from a specialist craft into a respected form of performance cruising. With his business partner Richard Eyre he set out to build a genuine ocean-going trimaran that combined performance, safety, comfort and simplicity and could be run by a couple — not a racer adapted for cruising, nor a cruiser with performance added afterwards. Its stated mission is to build the world's best ocean-cruising trimarans. For the design they engaged Morrelli & Melvin, the California naval architects founded by Gino Morrelli and Pete Melvin, whose credits include two multihull America's Cup winners, Stars and Stripes in 1988 and BMW Oracle Racing's trimaran in 2010. To build the boats, Koch and Eyre co-founded Triac Composites in Vietnam in 2014; its facility about 45 minutes from the centre of Ho Chi Minh City, with large CNC and robotic machinery and an 8.5-metre autoclave, builds every Rapido exclusively.
