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.

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

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

Roughly the speed a displacement hull reaches before it has to climb its own bow wave.

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 Allures Yachting

Semi-custom

French builder of aluminium blue-water cruising sailboats, founded in 2003 and part of the Grand Large Yachting group.

Allures Yachting was founded in 2003 as a French builder of aluminium sailboats for long-distance voyaging, from 40 to 52 feet. Its first generation of models started the story; by 2010 the yard was producing fifteen boats a year, had gained the industrial capacity to build its own hulls, and moved into a new building in Cherbourg where carpentry, equipment, deck and rigging were brought under one roof. The range was renewed in that period -- the 45 replaced the 44, the 52 succeeded the 51 in 2016, and the 40 evolved into the 39.9 -- and in 2017 a third generation began with the 40.9, 45.9 and 51.9, completed in 2021 with the 51.9, the first Allures with an aft cabin and a long cockpit. In 2019 an Allures 44 completed the Northwest Passage while an Allures 45 sailed Patagonia, and in 2025 the Horizon 47 revisited the bluewater cruising sailboat.
