Used Triangle One-Design Sailboats for Sale

The Triangle One-Design, an elegant classic sailboat, embodies the design ethos of legendary naval architect John G. Alden, known for crafting comfortable, seaworthy, and swift yachts. Originally referred to as the Marblehead Class or Jamestown Class, this monohull was conceived as a true one-design vessel, emphasizing competitive racing based on sailor skill rather than boat design advantages. Built by the esteemed Graves Yacht Yard in Marblehead, Massachusetts, the Triangle One-Design represents a notable chapter in American yachting history, particularly in the interwar period.
