Download Boat Record:


This was the first boat (other than dinghys) built by Pearson Yachts and one of the most successful. 150 were also built by Aeromarine in Sausalito, CA. An undetermined number were also built under license by Jouet in France. The Pearson Tritons were built with wood trim and coamings, while the Aeromarine Tritons are all fiberglass and a masthead rig. (Sailplan was changed a number of times for all versions.)
The Pearson TRITON was also available with a yawl rig.
