About the ISLANDER 37
A kit version was sold as the YACHTCRAFT 37.
Designed by Bruce King and built by Islander Yachts/Freeport Yachts (USA) from 1966–1972, the Islander 37 is a classic American cruising sloop with a production run of ? hulls. It is characterized by a 36.5 ft LOA, 14000.0 lb displacement, and a masthead sloop rig, offering a balance of performance and comfort with a comfort ratio of 29.44.
- Best for:
- This boat suits coastal cruisers and those seeking a comfortable, stable platform for weekend trips or short offshore passages, given its moderate displacement and cabin volume. It is less ideal for extreme bluewater racing due to its heavier displacement and traditional fin keel design.
- Bluewater capability:
- With a displacement of 14000.0 lb and a capsize ratio of 1.8, the Islander 37 is capable of offshore cruising but requires careful attention to structural integrity, particularly regarding the keel and deck joints, for safe bluewater passage-making.
- Comparables:
- Comparable boats include the Cal 34 and O'Day 36, which share similar eras, beam widths, and cruising-oriented designs. These vessels offer similar cabin layouts and performance characteristics, making them direct competitors in the used market.
