2026 Lagoon 55

The Lagoon 55 is a 55-foot catamaran built from fiberglass with twin 160-horsepower Yanmar diesel engines. Its design balances contemporary styling with Lagoon's traditional catamaran heritage, defined by clean lines and a distinctive profile that sets it apart on the water. The boat has won recognition for its design and engineering, including the 2021 Multihull of the Year Award from the British Yachting Awards and Best Sailing Catamaran Over 50 Feet at the 2021 Oceanway China Yacht Award.

The interior layout prioritizes openness and livability across a generous 29.5-foot beam. The Lagoon 55 Millennium edition offers six cabins of equal size and configuration, capable of accommodating twelve people. The galley is positioned centrally and scaled for full provisioning and meal preparation. Deck spaces include a redesigned aft cockpit with sightlines to the horizon and a flybridge for additional outdoor living.

Practical design runs throughout the boat. The aft transom has been reconfigured to improve flow and movement between interior and exterior spaces. The cockpit functions as an extension of living areas, while the flybridge and aft deck integrate seamlessly into daily life aboard.
