2026 Catamaran Diamond Yachts P55 Power Catamaran

The Diamond Yachts P55 is a 55-foot power catamaran built in fiberglass, designed around an open, flowing layout that connects interior and exterior spaces. The wide 26-foot beam supports generous social zones and uninterrupted sightlines, creating an environment suited equally to entertaining and extended cruising. European-influenced styling and refined finishes define the aesthetic—contemporary in execution but timeless in approach.

The catamaran platform delivers notable stability and volume efficiency. Twin 500-horsepower Yanmar diesel engines provide the power plant. The accommodation plan includes two cabins and two heads, with interiors thoughtfully integrated into the overall design philosophy.

The boat's defining characteristic is its indoor-outdoor layout, where open deck areas flow naturally into the main living spaces. The configuration prioritizes both comfort for living onboard and functionality for social gatherings. Every element of the design reflects purposeful integration rather than conventional separation of spaces.
