Length : beam is length divided by beam — the higher it is, the slimmer the hull. Multihulls read low by nature.

What the builders publish about how fast, how strong and how far — each figure on one scale for every boat.

Windelo 54
Classic yacht-design ratios worked out from each builder's published figures. They compare boats; they don't grade them.
How much sail the boat carries for its weight — its power in light air.
sail area (ft²) ÷ (displacement as ft³ of seawater)^⅔
Catana Ocean Class: mainsail + jib, added up
Windelo 54: 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
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.
The boats most like the ones above, by hull form, size and use.
