How this ranking is worked out

Upwind sail area in square feet divided by displaced volume in cubic feet to the power two-thirds (displacement in sea water at 1,025 kg/m³). Above about 20 is a powerful boat, 16–20 a performance cruiser, below 16 a heavier cruiser.

122 boats in the catalogue publish the figures this ranking needs. Only figures the builders themselves publish are used; a boat that does not publish one is left out, never estimated, and discontinued models are not ranked. Each model page names the builder's page its figures were read from.
