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.

23.9· Performance

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.

125· Light

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

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.

12.2· Light

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.

2.30· 2 and above

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.

6.2 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.

About Sunbeam Yachts

Premium production

Austrian family yard building sailing yachts since 1950 — today the SUNBEAM 22.1, 28.1, 29.1, 29.1 GT and 32.1, from 6.85 to 9.98 metres — run by the third generation of the Schöchl family and moving in 2026 from Mattsee to a new shipyard at Munderfing.

Sunbeam Yachts has been developing and building sailing yachts in Austria for more than seventy-five years, from its yard at Mattsee. It took the European Yacht of the Year award twice, in 2008 and in 2019. Part of what the yard aims at is reachability on land as well as water: the Sunbeam 22.1, 28.1, 29.1 and 29.1 GT are each under 2.5 metres in beam and under 3.5 tonnes, and so can be trailed behind a suitable vehicle without a special permit.
