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: displacement

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.

not published: displacement

How it is worked out

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

Ballast ratio

The share of the weight carried in the keel — a rough guide to stiffness, though how deep that weight sits matters as much.

not published: ballast, displacement

How it is worked out

ballast ÷ displacement × 100

Comfort ratio

Ted Brewer's measure of how gently a boat moves in a seaway. Higher means a slower, easier motion.

not published: displacement

How it is worked out

displacement (lb) ÷ (0.65 × (0.7 × LWL + 0.3 × LOA) × beam^1.333), lengths in ft

Capsize screening

A guide from the inquiry after the 1979 Fastnet race: below 2 was taken as suited to ocean passages. It ignores hull shape and where the ballast sits.

not published: displacement

How it is worked out

beam (ft) ÷ (displacement as ft³ of seawater)^⅓

Hull speed

Roughly the speed a displacement hull reaches before it has to climb its own bow wave.

11.0 kn

How it is worked out

1.34 × √(waterline length in ft), in knots

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.
