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.

ModestCruiserPerformanceRacing162024
  • not published: displacement
How it is worked out

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

Displacement / length

How heavy the boat is for its waterline length. Lower is lighter and quicker; higher is steadier and roomier.

UltralightLightModerateHeavyVery heavy100180270350
  • not published: displacement, waterline length
How it is worked out

displacement (long tons) ÷ (0.01 × waterline length in ft)³

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.

Design limits set by the EU Recreational Craft Directive (2013/53/EU), in significant wave height. A category covers the conditions of those below it. It is the limit the boat was designed to, not a promise that it is safe in any conditions within it — that judgement stays with the skipper.

About Sunreef Yachts

Custom

Polish builder of custom luxury catamarans from Gdańsk, founded in 2002 by Francis Lapp — the Sunreef 50 to 100 sailing catamarans, the 60 to 100 Sunreef Power motor catamarans, each in a Classic and a solar-electric Eco version, the Ultima 44 to 88 motor yachts with a BRABUS edition, and superyacht projects up to a 210-foot power trimaran.

Francis Lapp opened a shipyard in Gdańsk, a city with long traditions of naval construction, establishing Sunreef Yachts' production site and office there in 2002. In 2003 the yard launched the Sunreef 74 CHE, the world's first oceangoing luxury catamaran with a flybridge, which changed the philosophy of multihull design; the 70 Sunreef Power JAMBO of 2008, designed with Laurent Bourgnon, was the first double-deck power catamaran with oceanic range, and the Sunreef Ultimate line of high-performance sailing catamarans followed in 2010. Francis Lapp was named Entrepreneur of the Year at the 2013 World Yacht Trophies, the Sunreef Supreme 68 opened the Supreme range in 2016, and the yard marked fifteen years in 2017 as the Sunreef 88 Double Deck and 40 Open Sunreef Power collected Yacht Style awards in 2018 and 2019. In 2022 the Sunreef 80 Eco, the first yacht with Sunreef's solar skin, was launched and won the Gustave Trouvé Award, followed in 2023 by the German Innovation Award and Multihull of the Year.
