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.

25.1· Racing

How it is worked out

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

mainsail + jib, added up

Displacement / length

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

not published: waterline length

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 Catana Catamarans

Semi-custom

French builder of offshore cruising catamarans, founded in 1984, known for 40 years of innovation in composite construction and performance design.

Since 1984 Catana has pushed the boundaries of offshore sailing from France. The yard describes its history in eras: in 1996 it set the foundations of its DNA -- performance, safety and comfort -- through bold technical choices; in 2005 it introduced advanced composite materials, asymmetrical hulls and daggerboards, the technical basis of the modern Catana; from 2012 it built larger, more seaworthy and ever more innovative models, and from 2019 refined designs, ergonomics and construction. In 2026 the Ocean Class opened a new generation of catamarans built to sail far and long, with redesigned spaces and silence on board.
