About the DUNCANSON 25
Also available with a fixed keel.
The Duncanson 25 is a compact fractional sloop designed by Duncanson and built by Yacht Specialists S.A.Pty. Ltd. (AU) in 1982. With a displacement of 3360.0 lb and a beam of 8.01 ft, this vessel represents a specific era of Australian yacht construction, though the total number of hulls built remains unverified.
- Best for:
- This boat suits coastal cruisers and weekend sailors seeking a manageable, lightweight package that is easy to trailer and dock. Its fractional sloop rig and moderate sail area-to-displacement ratio of 18.45 make it accessible for single-handers or couples.
- Bluewater capability:
- With a low displacement of 3360.0 lb and a capsize ratio of 2.14, the Duncanson 25 is primarily suited for protected coastal waters rather than extended bluewater passages.
- Comparables:
- Comparable boats include other 25-foot trailerable cruisers from the early 1980s, such as the O'Day 25 or Catalina 25, which share similar fractional sloop rigs and coastal cruising roles. These vessels offer similar beam and draft characteristics, appealing to owners prioritizing ease of handling over heavy offshore performance.
