About the ALLMAND 23 (HMS 23)
Also called HMS 23. Available with fixed or swing keel. Inboard power available as an option. Built in very small numbers. Dimensions from builders literature.
The Allmand 23 (HMS 23) is a compact, lightweight sloop designed for easy handling and trailerability, built by Allmand Boats Inc. (USA) in 1975. With a displacement of 3360.0 lb and a beam of 9.5 ft, it represents a niche entry in the late-1970s market for small, performance-oriented day sailers.
- Best for:
- This boat is best suited for single-handers or couples seeking a trailerable day sailer for protected coastal waters, given its light displacement and manageable size.
- Bluewater capability:
- With a low displacement of 3360.0 lb and a capsize ratio of 2.54, the Allmand 23 is not recommended for extended offshore passages, as its light hull and fin keel are optimized for coastal day sailing rather than heavy-weather stability.
- Comparables:
- Comparable boats include the O'Day 23 and the Catalina 22, as they share similar length overall (23.0 ft) and target the same market of affordable, easy-to-handle weekend cruisers from the mid-1970s.
