Sail area / displacement
How much sail the boat carries for its weight — its power in light air.

Classic yacht-design ratios worked out from the builder's published figures, each shown against the bands designers read it by.
How much sail the boat carries for its weight — its power in light air.
sail area (ft²) ÷ (displacement as ft³ of seawater)^⅔
published upwind sail area
How heavy the boat is for its waterline length. Lower is lighter and quicker; higher is steadier and roomier.
displacement (long tons) ÷ (0.01 × waterline length in ft)³
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
Ted Brewer's measure of how gently a boat moves in a seaway. Higher means a slower, easier motion.
displacement (lb) ÷ (0.65 × (0.7 × LWL + 0.3 × LOA) × beam^1.333), lengths in ft
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.
beam (ft) ÷ (displacement as ft³ of seawater)^⅓
Roughly the speed a displacement hull reaches before it has to climb its own bow wave.
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.
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.
Certified CE design category B (Offshore): the wind and waves the EU Recreational Craft Directive says this boat is designed to take.
Sheltered waters
Inshore
Offshore
Ocean
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.

Volume production
German builder of cruising sailing yachts, founded in Greifswald in 1990 and built by HanseYachts AG.
HanseYachts was born in 1990 and unveiled its first series-built yacht, the Hanse 291, at the Hamburg Boat Show in 1993; the 331 followed a year later, the 401 in 1997 brought modern design, the 292 won European Yacht of the Year in 1998, and in 1999 the partnership with judel/vrolijk & co began with the 371. The 311 and 331 took European Yacht of the Year in turn, the 531 of 2003-04 set a new standard with a loft-style interior by Birgit Schnaase, and by 2005 the Easy Sailing concept, one-rope reefing and a six-model range had made the brand's name -- the yard was officially named HanseYachts in 2006, the year of the speed-focused 430, and the 630e introduced the world's first intelligent hinged armature system. The 2010s brought the 375 and 545, then the 455 with the largest cockpit in its class, the 315 that led the way into e-mobility with an award-winning rudder drive, the 675 and 588, and the 348, 388, 418 and 548 premiered at Cannes. From 2018 Hanse moved from judel/vrolijk to the French designers Berret-Racoupeau, whose award-winning Hanse 460 opened the current fleet, joined by the 510 and 410 -- all built in Greifswald.
