Trapper 500
Description
The Trapper 500 (often called the Trapper 500/501) is a 27.33–28.17-foot (LOA approx. 27'4"–28'2") masthead sloop designed by Rob Ball of Camper & Nicholson (with roots in the C&C 27 design by Cuthbertson & Cassian). It was built in fiberglass by Anstey Yachts (later renamed Trapper Yachts Ltd.) in Poole, England, from 1977 to 1987. The 501 variant (introduced in 1981) used the same hull but featured an updated coachroof and interior moldings for more luxury; late 500s often incorporated 501-style interiors. Approximately 600 boats were built in total (including both variants), making it one of Trapper Yachts' more successful models. The boat is a solid, affordable racer-cruiser with a fin keel (or rare bilge keel), spade rudder, and practical layout for 5–6 people, known for good all-around performance, stability, and value in the used market.

Sailrite does its best to publish accurate dimensions, but we often find it worthwhile to have our customers measure their boats carefully before we produce kits for them.
