Length : beam is length divided by beam — the higher it is, the slimmer the hull. Multihulls read low by nature.
Classic yacht-design ratios worked out from each builder's published figures. They compare boats; they don't grade them.
Sail area / displacement
How much sail the boat carries for its weight — its power in light air.
ICE 80 Sportnot published: sail area
Mylius M80RS27.7· Racing
How it is worked out
sail area (ft²) ÷ (displacement as ft³ of seawater)^⅔
Mylius M80RS: published upwind sail area
Displacement / length
How heavy the boat is for its waterline length. Lower is lighter and quicker; higher is steadier and roomier.
ICE 80 Sportnot published: waterline length
Mylius M80RS93· Ultralight
How it is worked out
displacement (long tons) ÷ (0.01 × waterline length in ft)³
Ballast ratio
The share of the weight carried in the keel — a rough guide to stiffness, though how deep that weight sits matters as much.
ICE 80 Sportnot published: ballast
Mylius M80RS35· Moderate
How it is worked out
ballast ÷ displacement × 100
Comfort ratio
Ted Brewer's measure of how gently a boat moves in a seaway. Higher means a slower, easier motion.
ICE 80 Sportnot published: waterline length
Mylius M80RS26.6· Coastal
How it is worked out
displacement (lb) ÷ (0.65 × (0.7 × LWL + 0.3 × LOA) × beam^1.333), lengths in ft
Capsize screening
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.

Hull speed
Roughly the speed a displacement hull reaches before it has to climb its own bow wave.

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.
