Key differences

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.

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

Total engine power per tonne of published displacement — more means livelier acceleration for the hull. Drawn for motor yachts.

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