Pearson Triton (Masthead Rig MK IV)
Description
The Pearson Triton (Masthead Rig Mk IV) refers to a masthead sloop variant of the classic Carl Alberg-designed Triton, primarily built by Aeromarine Plastics in Sausalito, California, starting in 1960. Unlike the original Pearson Yachts production (fractional sloop or yawl rigs), this version features a taller masthead rig optimized for larger headsails and easier heavy-weather handling with inner forestay options, though it trades some light-air performance for stability. Approximately 150 units were produced under license (owned by Grumman, as was Pearson), with solid fiberglass construction throughout—no wood trim or coamings—making them more robust against rot but slightly heavier. The hull retains the iconic long-keel design inspired by Scandinavian Folkboats, emphasizing seaworthiness for coastal and offshore cruising, and it shares the same affordable, family-oriented appeal that made the Triton a fiberglass pioneer.
