The Granocean 55 actually measures 57' , and is a very spacious power catamarans with an impressive 8.7m / 28' beam. Flared hulls combined with a high bridge deck clearance provide a smooth riding platform and unmatched living space.

The unique flybridge wings provide ample open space to lounge or a store a large tender atop while providing much needed coverage over the cockpit and engine room hatches. The enclosed fly-bridge allow you to appreciate both hot and cold climates. The open salon offers 360 degree views, and a very private Master Cabin with ensuite head and shower, king size bed and ample hanging storage allow for spending weeks or months in a row onboard.

Twin Cummins engines can propel the boat over 20 knots, or cruise at 8-10 knots with excellent efficiency.
