Pearson Triton 28 (fractional rig)
Description
The Pearson Triton 28 (Fractional Rig) is the iconic original configuration of Carl Alberg's groundbreaking fiberglass sailboat, launched in 1959 as an affordable racer-cruiser blending traditional lines with modern materials. This fractional sloop variant—distinguishing it from later masthead or yawl options—features a shorter mast (stepped on the deck) with the forestay attached about two-thirds up, allowing a larger mainsail relative to the headsail for balanced power and easier handling. With its long keel, spooned bow, and low freeboard inspired by Scandinavian Folkboats, it prioritizes seaworthiness and simplicity, sleeping four in a compact yet functional layout. Over 650 units were built by Pearson Yachts, cementing its status as a pioneer in mass-produced fiberglass boats under $10,000. Designed in 1958 at the request of broker Tom Potter for a durable coastal/offshore 28-footer, the Triton debuted at the 1959 New York Boat Show, where the prototype drew 17 orders in a single night. Pearson Yachts, founded by brothers Everett and Clinton Pearson in 1956, ramped up hand-laid fiberglass production in Portsmouth, Rhode Island, emphasizing quality amid the shift from wood to composites. The fractional rig was standard on early models, with yawl and masthead options added later; licensed builds in France (Jouët) and California (Aeromarine) stuck to sloops but varied in detail. Production ended in 1967 after ~700 total Tritons, but the design's affordability ($9,700 equipped) and performance fueled the small-boat revolution, earning induction into the American Sailboat Hall of Fame in 1995.
