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.

33.0· Racing

How it is worked out

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

mainsail + genoa, added up

Displacement / length

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

96· Ultralight

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.

Speed & Tanks

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.
