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.

16.3· Cruiser

How it is worked out

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

published upwind sail area

Displacement / length

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

271· Heavy

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.

33· Moderate

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.

38.3· Moderate offshore

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.

1.69· Below 2

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.

8.0 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.

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 Najad Yachts

Premium production

Swedish manufacturer of luxury sailing yachts, based on the island of Orust since 1971.

Najad was founded in 1971 at Henån on Orust, the Swedish island that builds more sailing yachts per square kilometre than anywhere else in the world, with a simple aim: the finest bluewater cruising yacht in Sweden. More than fifty years on, every Najad is still built by hand at Henån, where the joinery, the laminate schedule and the rigging layout are each worked out rather than left to chance. The boats have circumnavigated, crossed the Atlantic many times over, and come back.
