Best Suited For

Tags are derived from certified class, length, sail area, accommodation and tankage using the criteria described on the Sources page; an editor may add or remove one.

Sailing Ratios

Classic yacht-design ratios worked out from the builder's published figures, each shown against the bands designers read it by.

Sail area / displacement

How much sail the boat carries for its weight — its power in light air.

How it is worked out

sail area (ft²) ÷ (displacement as ft³ of seawater)^⅔

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.

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.

Comfort ratio

Ted Brewer's measure of how gently a boat moves in a seaway. Higher means a slower, easier motion.

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

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.

Tanks

What the builder publishes about how fast, how strong and how much the boat carries.

Fuel and water on one scale: a tank twice the height holds twice as much.

About Tartan Yachts

Semi-custom

American builder of performance cruising sailboats from Painesville, Ohio — six vacuum-infused models from the all-new Tartan 27 to the 16.3-metre Tartan 53, all with self-tacking jibs, carbon rigs and a choice of deep-fin, Beavertail or keel-centreboard underbodies, built in low volume by Ohio craftsmen.
