Wallypower 118 Yacht

118 WallyPower is a 118-foot (36 m) luxury motor yacht with a maximum speed of 60 knots (70 mph, 110 km/h) produced by Wally Yachts. The yacht is narrow and angular in design with black glass housing, driven by three Vericor TF50 gas turbines generating 5,600 horsepower (4,200 kW), each driving a Rolls-Royce Kamewa water jet, two steerable outboard and a non-steering booster on the centerline. The steerable water jets also have a diesel engine input for a 370 hp (280 kW) Cummins diesel, and are thus Combined Diesel or Gas Turbine (CODOG). The total power output is 16,800 horsepower (12,500 kW). One 118 WallyPower has been constructed, and is in the Mediterranean as of 2008.
Construction
The hull of the 118 WallyPower is the result of an extensive R&D program including tank testing at the SSPA facility in Gothenburg, Sweden, and smoke testing in the Ferrari Wind Tunnel Facility in Maranello, Italy. It is stable at speed as a result of the deep V (22 degrees) hull shape and a straight stem bow designed to pierce waves.
