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.

ModestCruiserPerformanceRacing162024
  • not published: sail area, 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.

UltralightLightModerateHeavyVery heavy100180270350
  • not published: displacement, waterline length
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.

LowModerateHigh3040
  • 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.

LightCoastalModerate offshoreHeavy offshoreVery heavy20304050
  • not published: displacement, waterline length
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

Hull speed

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

  • not published: waterline length
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 Jeanneau

Volume production

French builder of sailing and motor yachts, founded in Les Herbiers in 1957 by Henry Jeanneau.

In 1957 Henry Jeanneau, already a lover of aeroplanes and cars, discovered powerboating watching a boat pass his window, built a wooden hull at Les Herbiers and won the 6-hour Paris race with it -- a pastime became a trade. The yard built its first fibreglass hull in 1958, its first production powerboat, the Sea Bird, in 1963, and its first sailboats with the Alizé in 1964; sailing was democratised through the 1970s, a Melody raced the single-handed transatlantic in 1976, and from 1980 Jeanneau went powerboat racing, later setting a production-engine speed record of 170.21 km/h in 1987. Between 1982 and 1998 Jeanneau was the exclusive supplier of the Sailing Tour de France, the Sun Kiss of 1983 became a reference among large cruisers, the Fleury Michon catamarans built for Philippe Poupon won the Route du Rhum in 1986 and the transatlantic record in 1987, the first Lagoon catamaran was built in 1985 and the first Prestige, by Garroni Design, in 1989. Jeanneau America was created in 1996, the Sun Odyssey line drove the 2000s, the Sun Fast 3200 of 2008 was European Yacht of the Year, the Jeanneau 64 of 2014 was the first production yacht over sixty feet, the sixtieth anniversary came in 2017 with production of the NC 895 starting in Cadillac, Michigan, and the walk-around decks arrived on cruising sailboats in 2018.
