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.

Drawings side by side

Each boat's layouts, profiles and sail plans as its builder published them. Step through each column to line up the drawings you want to compare.

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.

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.
