About the INTERNATIONAL 23
Keel version - draft:2.5'/.76m
Designed by Helsen and built by International Yacht Corp. (USA) in 1975, the International 23 is a compact masthead sloop with a displacement of 3090.0 lb and a beam of 8.0 ft. While the exact hull production count is unknown, this model represents a specific vintage of American trailerable cruising yachts.
- Best for:
- This boat suits coastal cruisers and trailerable boat owners seeking a manageable package for day sailing and short overnight trips, supported by widespread adoption of solar panels and bimini tops for self-sufficiency.
- Bluewater capability:
- With a low displacement of 3090.0 lb and a comfort ratio of 14.24, the International 23 is primarily a coastal cruiser rather than a bluewater passagemaker, though its capsize ratio of 2.2 suggests reasonable stability for protected waters.
- Comparables:
- Comparable to other 1970s trailerable sloops like the O'Day 23 or Catalina 22, the International 23 shares similar dimensions and a focus on ease of transport, though it distinguishes itself with a slightly heavier displacement and specific Helsen design lines.
