Sailing Ratios
Classic yacht-design ratios worked out from the builder's published figures, each shown against the bands designers read it by.
Displacement / length
How heavy the boat is for its waterline length. Lower is lighter and quicker; higher is steadier and roomier.
- 109· 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.
- 30.6· 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.
- 1.92· 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.
- 11.4 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.

About Grand Soleil
Premium production
Italian builder of performance-oriented sailing yachts, established over 50 years ago, part of Cantiere del Pardo S.p.A.
The Grand Soleil Line is where the brand began, more than fifty years ago, and it remains its core: sailing yachts under 65 feet built by Cantiere del Pardo. What the yard calls its dual DNA is the refusal to make an owner choose between speed and comfort -- on one side a racing heart, pushing for hydrodynamics, sail plans that are powerful but manageable, and current construction; on the other the long-distance line, with the volume, range and stowage of a home at sea. The racing half is not a slogan: Grand Soleils have won the IMS and ORC world championships more than once, and raced the Fastnet, the Rolex Giraglia and the Middle Sea Race.
