About the ANTRIM 27
Designed by Jim Antrim and built by Ultimate Sailboats International, the Antrim 27 is a lightweight, performance-oriented fractional sloop produced in 1996. With a displacement of 2600.0 lb and a beam of 9.25 ft, it offers a high sail area-to-displacement ratio of 41.48, prioritizing speed and agility over heavy displacement comfort.
- Best for:
- This boat is ideal for coastal cruisers and day sailors who prioritize performance and ease of single-handed handling, given its light displacement and fractional rig. It suits owners willing to perform proactive maintenance on its composite structure and systems, as it is less suited for heavy-weather offshore passage-making.
- Bluewater capability:
- With a low displacement of 2600.0 lb, a capsize ratio of 2.69, and a comfort ratio of 8.31, the Antrim 27 is primarily a coastal cruiser with limited bluewater capability due to its light weight and reported structural vulnerabilities in the keel and deck core.
- Comparables:
- Comparable boats include the O'Day 27 and Catalina 27, which share similar beam and fractional rig configurations but typically feature heavier displacement and different hull forms. The Antrim 27 distinguishes itself with a significantly lower displacement of 2600.0 lb and a higher sail area-to-displacement ratio, making it faster but less stable in rough conditions.
