Fitzroy launched Salperton IV last year following the success of Salperton III. The Ed Dubois-designed boat, designed to be a fast cruising yacht, can reach 25 knots and is designed to travel long distances around the world. The boat has a 573-square-ft. mainsail with an impressive total sail area of 3752 square feet. The Adam Lay interior is sophisticated but not ostentatious. Salperton IV can carry up to eight guests and six crew. The yacht is another triumph for Fitzroy, a New Zealand builder that has made its name lately with successive large sailboats.
