About the CORBY 25
Also called AXION 25.
The Corby 25 is a 25.0 ft fractional sloop designed by John Corby and built by Lion Yacht, with production records indicating a build year of 2003. With a displacement of 4630.0 lb and a beam of 8.2 ft, this vessel represents a compact, performance-oriented cruiser that prioritizes sailing dynamics over heavy displacement comfort.
- Best for:
- This boat is best suited for coastal cruisers and weekend sailors who value responsive handling and ease of single-handed operation over heavy offshore endurance. Its fractional rig and moderate displacement make it ideal for those seeking a manageable, trailerable package for local waters.
- Bluewater capability:
- With a capsize ratio of 1.97 and a comfort ratio of 18.4, the Corby 25 is primarily designed for coastal cruising rather than extended bluewater passages, though its fin keel and 6.1 ft max draft provide adequate stability for protected offshore work.
- Comparables:
- Comparable vessels include the Beneteau First 23 and the O'Day 23, as they share similar fractional sloop rigs and target the same market of entry-level performance cruisers. The Corby 25 distinguishes itself with a slightly heavier displacement (4630.0 lb) and a more modern hull form compared to these contemporaries.
