2026 Lagoon 55

The Lagoon 55 is a 55-foot fiberglass catamaran with a 29.5-foot beam, powered by twin 160-horsepower Yanmar diesel engines. Her design balances contemporary styling with Lagoon's established heritage, featuring distinctive lines and bold proportions that define the model's visual identity.

The interior layout accommodates up to twelve guests across six cabins of equal size, each with identical amenities. A generous central galley serves the accommodations, while the redesigned cockpit and flybridge provide practical living and social spaces. The aft deck functions as an expansive outdoor terrace, offering unobstructed views and serving as the focal point for time spent on the water.

Interior spaces emphasize comfort and seclusion, with generous cabin volumes and thoughtful layouts designed to maximize privacy and relaxation. The reconfigured aft transom improves traffic flow and on-deck functionality, creating an efficient relationship between indoor and outdoor living areas.
