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

Length : beam is length divided by beam — the higher it is, the slimmer the hull. Multihulls read low by nature.

Size, to scale
Each boat's published length and beam seen from above, and its mast height and draft from the side, all drawn on one scale.
Outlines are schematic; the dimensions are the builder's.
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.
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.
- GS Plus 72 LC32.6· Racing
- Swan 7327.5· Racing
How it is worked out
sail area (ft²) ÷ (displacement as ft³ of seawater)^⅔
GS Plus 72 LC: published upwind sail area
Swan 73: mainsail + jib, added up
Displacement / length
How heavy the boat is for its waterline length. Lower is lighter and quicker; higher is steadier and roomier.
- GS Plus 72 LC113· Light
- Swan 73113· Light
How it is worked out
displacement (long tons) ÷ (0.01 × waterline length in ft)³
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.
- GS Plus 72 LCnot published: ballast
- Swan 7322· Low
How it is worked out
ballast ÷ displacement × 100
Comfort ratio
Ted Brewer's measure of how gently a boat moves in a seaway. Higher means a slower, easier motion.
- GS Plus 72 LC28.7· Coastal
- Swan 7333.5· Moderate offshore
How it is worked out
displacement (lb) ÷ (0.65 × (0.7 × LWL + 0.3 × LOA) × beam^1.333), lengths in ft
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.
- GS Plus 72 LC1.96· Below 2
- Swan 731.82· Below 2
How it is worked out
beam (ft) ÷ (displacement as ft³ of seawater)^⅓
Hull speed
Roughly the speed a displacement hull reaches before it has to climb its own bow wave.
- GS Plus 72 LC10.9 kn
- Swan 7311.2 kn
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.
