Pearson Triton

The Pearson Triton is Carl Alberg's 28-foot full-keel sloop, introduced at the January 1959 New York National Boat Show and generally regarded as the first production fibreglass auxiliary cruiser to sell in volume. Pearson built roughly 750 on the East Coast between 1959 and 1967, Aeromarine Plastics built a further 125–150 under licence in Sausalito, California, and Jouët built about 60 in France. Long overhangs, low freeboard, a folkboat-like hull and a heavy laminate have made it a durable 'plastic classic' with an active owners' scene.

Cousins Clint and Everett Pearson had been building dinghies in a Bristol, Rhode Island basement when Tom Potter brought them Alberg's design; the Triton took 16 orders at the 1959 show and put Pearson Yachts on the map. Grumman bought a controlling interest in 1961 and production moved to a large plant in Portsmouth, RI. Early Pearson boats had single lower shrouds (double lowers became standard after about hull #120) and external lead ballast; after about hull #385 the lead was lowered into the keel cavity and glassed over, widening the keel two inches and adding about an inch of draft. Production ended in 1967 as Bill Shaw's newer Pearson designs took over.

Alberg drew a 21'6" waterline on a 28'4" hull with a spoon bow, moderate sheer and a long keel whose forefoot is well cut away, the rudder hung on the keel's trailing edge. The standard rig is a three-quarter fractional sloop with jumper struts and a large mainsail; a shorter masthead rig and a yawl were later offered. Displacement is about 6,930 lb on 3,019 lb of lead (later internal-ballast boats are heavier). Practical Sailor describes hull thickness from about 3/8 inch at the rail to 3/4 inch at the keel; the original rudder was mahogany on bronze drift pins, since replaced on many boats. Power was the 30 hp Universal Atomic 4.

Counts differ by source. The Pearson Yachts Portal and Pearson history give about 750 East Coast boats; Practical Sailor and Wikipedia say 'more than 700'. For the West Coast boats the Portal says about 125 and Wikipedia (citing sailboatdata) 150; the sources cannot be reconciled so no West Coast count is set. Wikipedia adds about 60 Jouët boats in France from 1965. No source states a combined total, so production_count is left unset; the family as a whole is in the region of 900–950 hulls.

The West Coast (Aeromarine) Triton is modelled as an option plus aliases rather than a generation: it is the same Alberg hull from Pearson's tooling, sold under the same name and years, differing in deck construction, trim and rig. A buyer does search for 'West Coast Triton', which is why the aliases exist, but the differences are configuration-level (rig type) rather than a new hull or model year, and no spec table specific to the Aeromarine boat could be read from a citable source. The Jouët Triton with its windshield deck is a further licensed build recorded as a production run. Rig options on Pearson boats were the standard fractional sloop, a later masthead rig and a yawl.

Deck core delamination and a mast support beam that lets the deck sag under the mast are the most common structural problems on East Coast boats (West Coast decks are solid glass). Practical Sailor also lists aluminium spreader-socket castings that break, electrolysis of the bronze rudder shoe, rotting wooden bilge supports, a poor side-loading icebox and dark, chipping plywood-veneer joinery. Most surviving boats have replacement rudders, engines and standing rigging.

Prices are low, so the state of the deck decides value: check the core with a moisture meter, look for compression at the mast step and beam, and inspect chainplates and the forward lower shroud attachments. Establish whether ballast is external (pre-#385, keel bolts to inspect) or internal (no bolts, but check the glassed-over cavity). Expect a replaced engine, a fibreglass rudder and modern reefing on most boats. West Coast boats and boats with complete Atom Voyages-style refits carry a premium.

James Baldwin sailed the Triton Atom around the world twice in the 1980s, and Practical Sailor records numerous trans-oceanic passages by others; the 1990 Hurricane Hugo survivor cited by Practical Sailor lost its deck to other boats dragging onto it but kept a sound hull.
