Classic yacht-design ratios worked out from the builder's published figures, each shown against the bands designers read it by.

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
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.

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.

Semi-custom
French builder of ocean-going sailing catamarans, based in Les Sables d'Olonne since 1985.
Privilège Marine has been building ocean-going catamarans for more than forty years from its yard at Les Sables d'Olonne, on the French Atlantic coast -- a town shaped by maritime culture and offshore racing. The yachts are meant to cross oceans with confidence and to last, and innovation is admitted only where it serves reliability and long-term performance rather than novelty. No two are alike, which follows from how they are made: each project starts as a conversation about a way of sailing and a rhythm of life aboard, and the layout, circulation, materials and technical configuration are settled from there.
