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

Each boat's published length and beam seen from above, and its mast height and draft from the side, all drawn on one scale.
Outlines are schematic; the dimensions are the builder's.
What the builders publish about how fast, how strong and how far — each figure on one scale for every boat.

Wauquiez Pilot Saloon 48e
X4.9 MkII
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
Wauquiez Pilot Saloon 48e: 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.
The boats most like the ones above, by hull form, size and use.
