The Pearson Vanguard is a classic sailboat designed in 1962 by Philip Rhodes. These boats were built by Pearson Yachts from 1963-1967. Pearson Vanguards are a classic cruiser known for world travel.
Their hulls, like most early fiberglass boat hulls, are known for being significantly thicker than more modern fiberglass construction. The original engine was an "Atomic 4" gasoline engine however many have been replaced with marine diesels. The full shoal-draft keel has a 4400 pound lead ballast embedded into it.
404 of these classic hulls were made. There is an active Owners' Group at Yahoo! Groups.
