Key differences

Worked out from the published figures below — arithmetic, not opinion.

At a glance

Dark icons are the standard layout; faded ones are what the larger layout adds.

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

Speed, power & tanks

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

Tanks

One scale per liquid across every boat: a tank twice the height holds twice as much.

How they sail, in numbers

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.

Displacement / length

How heavy the boat is for its waterline length. Lower is lighter and quicker; higher is steadier and roomier.

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.

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.

How it is worked out

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.

Worth adding to this comparison

The boats most like the ones above, by hull form, size and use.
