2026 Lagoon 55

The Lagoon 55 is a 55-foot fiberglass catamaran powered by twin 160-horsepower Yanmar diesel engines. Contemporary in design with distinctive styling, the hull combines Lagoon's established heritage with modern lines that set it apart on the water.

The layout centers on spacious interior volumes and a generous aft cockpit designed as a true outdoor terrace. The Millennium edition offers six cabins of equal size, each with identical features, and accommodates up to twelve people. An enlarged central galley and redesigned flybridge support both living comfort and practical movement throughout the boat.

The wide beam of 29.5 feet supports the open, comfortable layout both below and on deck. Extended outdoor spaces and interior dimensions prioritize comfort and livability for extended cruising or charter use.
