Best Suited For

Tags are derived from certified class, length, sail area, accommodation and tankage using the criteria described on the Sources page; an editor may add or remove one.

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.

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.

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.

ballast ÷ displacement × 100

Comfort ratio

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

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.

Hull speed

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

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.

    5 gal of water per berth

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 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.
