Who cares if the fish aren’t biting? Just kicking back in the 118-ft 118 WallyPower luxury power boat made by Wally Yachts in Monaco should be vacation enough. But if speed is your thing, the boat can cruise at 60 knots for over 6 hr. Throttling back to 9 knots extends the range to 1,500 nautical miles on a tankful. Granted, the boat carries a 5,812-gallon fuel tank, but it burns 15 gallons/nm when going 60 knots. And if you can afford the nearly $25 million price tag, the price of gas shouldn’t bother you. Power is proved by three 5,600-hp Vericor gas turbines. Each turbine drives a Rolls-Royce Kamewa waterjet, giving it left and right steerable jets and one nonsteering booster on the centerline. The waterjets can also be powered by a 370-hp Cummins diesel, making it a combined diesel and gas turbine or CODOG. If you’re looking to cut corners, a twin-diesel version, which includes the waterjets, goes for just $17 million.

The boat displaces 95 tons and carries a crew of six plus six passengers. Below the waterline, the boat is constructed of fiberglass. Above that, fiberglass/ carbon composite over a balsa wood core forms the structure. The deck, which is covered in teak, is Nomex/carbon composite. The superstructure is also covered in panels made of triple-laminate glass and Lexan. Interior bulkheads carry no loads, so they are thin wood and laminate veneers over lightweight cores. Bath fixtures, dining tables, and some chairs are carbon composite to save weight. Currently, there’s only one of these super yachts plying the seas.
