What it is for

Liveaboard

Liveaboard: YachtCodex lists 463 models, 11.2–24.0 m long. The builders with the most are ICE Yachts (20), Beneteau (16), and Hallberg-Rassy (15). The largest in production is the ICE 80 Blue Water Sport (24.0 m); the shallowest draft is the Seawind 1600's (0.60 m).

Boats with enough room, water and plumbing to be lived on rather than visited. The criteria are a length overall between 11 and 24 metres, three cabins or more, two heads or more where the builder publishes a number, and 300 litres of fresh water or more where that is published; day boats, sport cruisers, centre consoles and racers are excluded. A figure the builder never published does not disqualify a boat on the secondary conditions -- unknown is read as not contradicting -- but cabins and length must be there.
