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
mainsail + jib, added up
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.
18 gal of water per berth

Premium production
French builder of luxury sailing catamarans, based in Rochefort sur Mer since 1994.
Nautitech began in 1994 as a line of catamarans created by the Dufour Yachts group. A change of owner in 2002 brought a new product line, and between 2004 and 2006 the yard set up its own production in La Rochelle and launched the Nautitech 44 and 40; in 2008-09 it moved to the Rochefort site and launched the 441 and 442, the first 54 was presented in 2011, and the 40 Open was unveiled at the Multihull show in 2014. That year Bavaria Yachts bought Nautitech and extended the production lines, giving the yard the industrial means to grow: the 46 Open followed at La Grande Motte in 2016, the 47 Power at boot Düsseldorf in 2018, the new 46 in Open and Fly versions at Cannes in 2019 and the new 47 Power in Miami in 2020; the production tooling was modernised into a multi-product line in 2021, and the 44 Open was launched in 2022.
