Introducing the revolutionary Lagoon 51, a cutting-edge model reshaping luxury and performance in sailing catamarans.

A standout feature is the forward-moved mast, enhancing the layout with a meticulously designed flybridge, spacious sun pads, and unobstructed views from the saloon. Extended transoms offer effortless access, integrating a beach deck with the hi-low tender platform, all on one level.

This example spec features a fully-equipped Owner's suite in the starboard hull, with a luxurious cabin, heads, and dressing room. The port hull accommodates three double cabins, with a spacious saloon and galley centrally located, complemented by a large aft cockpit.

Powered by Yanmar 80hp engines with folding props, the Lagoon 51 boasts Raymarine electronics, the elegance package, air conditioning, a generator, composite flybridge bimini, and a tender-lift platform, among other premium features.

We offer part exchanges and marine finance options, including monthly or quarterly payments with competitive rates.
