About the KAPPA-SAN 35
Also called KAPPA 35. Probably the same or similar to INTERNATIONAL MARINE 35. Additional information has been promised.
The Kappa-San 35 is a rare, heavy-displacement cruising sloop designed by McInnis and built by International Marine Japan Ltd. (JAP) in 1950. With a build count of ? hulls, this vessel represents a unique example of mid-century Japanese boatbuilding, featuring a full keel and substantial displacement of 14119.0 lb.
- Best for:
- This boat is best suited for experienced coastal cruisers or those seeking a slow, stable, and traditional sailing experience, rather than high-performance racing or short-handed offshore passages.
- Bluewater capability:
- With a high displacement-to-length ratio of 374.82 and a low capsize ratio of 1.66, the Kappa-San 35 possesses the inherent stability and motion comfort suitable for protected coastal cruising, though its age and single build year limit verified bluewater pedigree.
- Comparables:
- Comparable vessels include other 1950s full-keel, heavy-displacement sloops such as the Pearson 35 or early Catalina models, which share similar comfort ratios and conservative hull forms.
