America’s Cup Pedigree | Championship-Level Refit | Turn-Key Racing Inventory

Enterprise is a 1977 Sparkman & Stephens–designed 12 Metre, built by Minneford Yacht Yard as a U.S. defender candidate for the America’s Cup. Designed by Olin Stephens and David Pedrick, she was among the most technically advanced yachts of her era, incorporating extensive tank testing, early laminate sail development, and forward-looking performance modeling.

Between 2019 and 2023, Enterprise underwent a comprehensive, no-expense-spared restoration and modernization program. Today she stands as one of the best-prepared and most competitive modern 12 Metres, combining classic pedigree with modern race-boat systems and a deep, current sail inventory—offered as a true turn-key campaign platform.
