Sail area / displacement
How much sail the boat carries for its weight — its power in light air.
- not published: sail area, displacement

Classic yacht-design ratios worked out from the builder's published figures, each shown against the bands designers read it by.
How much sail the boat carries for its weight — its power in light air.
sail area (ft²) ÷ (displacement as ft³ of seawater)^⅔
How heavy the boat is for its waterline length. Lower is lighter and quicker; higher is steadier and roomier.
displacement (long tons) ÷ (0.01 × waterline length in ft)³
The share of the weight carried in the keel — a rough guide to stiffness, though how deep that weight sits matters as much.
ballast ÷ displacement × 100
Ted Brewer's measure of how gently a boat moves in a seaway. Higher means a slower, easier motion.
displacement (lb) ÷ (0.65 × (0.7 × LWL + 0.3 × LOA) × beam^1.333), lengths in ft
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.
beam (ft) ÷ (displacement as ft³ of seawater)^⅓
Roughly the speed a displacement hull reaches before it has to climb its own bow wave.
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.

Premium production
Italian builder of high-performance sailing monohulls, headquartered in Molfetta with its production shipyard in Castelvecchio, whose first model was the Italia 10.98 of 2010.
Italia Yachts began with the Italia Yachts 10.98 and has built high-performance boats since, drawn by a team of sailors whose aim is a hull, deck and sail plan that agree with one another. The yard's stated ambition is to hold together two things usually opposed: the efficiency of industrial production and the hand knowledge of the craftsman, with checks rigorous enough to keep quality even across the range. A new production yard opened in 2022, bringing every stage in-house, and in 2023 the IY 43 Veloce arrived -- the first motorboat Italia Yachts has signed, and one drawn, it says, with the soul of a sailing boat.
