Lagoon catamaran is a brand of twin-hulled boats that are designed and produced in Bordeaux, France. The company began in 1984 as a specialist multihull offshoot of Jeanneau, a volume monohull constructor. Jeanneau was subsequently purchased by Beneteau, another French manufacturer. Lagoon is the world's largest multihull builder. Most models are available in a charter version and an owner's version.
