Speed, Power & Tanks

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

Power to weight

Total engine power per tonne of published displacement — more means livelier acceleration for the hull. Drawn for motor yachts.

not published: engine power, displacement

Tanks

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.
