About the ANTRIM 20
Featured in 'Cruising World'; Jul-Dec., 1981 If any were ever built is unknown.
The Antrim 20 is a compact fractional sloop designed by Jim Antrim and built in 1982. With a hull count of ?, this vessel represents a specific era of small-craft design, featuring a 20.42 ft LOA and a lightweight displacement of 1850.0 lb.
- Best for:
- This boat is best suited for coastal day sailing and light cruising, appealing to owners who prioritize ease of handling and storage over long-range passage making. Its fractional sloop rig and 8.0 ft beam suggest a focus on performance in protected waters rather than heavy-weather stability.
- Bluewater capability:
- With a low displacement of 1850.0 lb and a capsize ratio of 2.61, the Antrim 20 is not recommended for serious bluewater passage making due to its light weight and limited ballast of 750.0 lb.
- Comparables:
- Comparable boats include the O'Day 23 and the Catalina 22, as they share similar beam dimensions and fractional sloop rigs from the same late-1970s to early-1980s era. These vessels also target the entry-level cruiser market with similar displacement ranges and fin keel configurations.
