About the ISLANDER 55
Only a few were built by Islander/Wayfarer. It is believed that the molds for the hull were sold to Tradewinds Yachts which built at least three cruising versions as the TRADEWINDS 55. A kit version was sold as the YACHTCRAFT 55.
The Islander 55 is a rare, large cruising sloop designed by Bruce King and built by Wayfarer Yacht Corp./Tradewinds Yachts (USA) with production years listed as 1968. With a build count of ?, this vessel represents a unique entry in the classic yacht market, characterized by its substantial 38000.0 lb displacement and 54.67 ft LOA.
- Best for:
- This boat suits experienced coastal cruisers and bluewater adventurers who prioritize spacious interior volume and heavy displacement comfort over high-performance racing metrics. It is well-suited for couples or families seeking a stable, comfortable platform for long-range cruising, provided they are prepared for significant maintenance.
- Bluewater capability:
- With a D/L ratio of 363.6 and a capsize ratio of 1.67, the Islander 55 is well-suited for offshore passage-making due to its heavy displacement and stable hull form. Its 36.0 ft LWL and full keel design contribute to a comfortable motion in heavy seas, though its age requires careful structural assessment.
- Comparables:
- Comparable boats include the Cal 50 and O'Day 50, which share similar eras and roles as large, comfortable cruising sloops with substantial displacement. These vessels offer similar interior volumes and offshore capabilities, making them direct competitors for buyers seeking a 50-foot+ classic cruiser.
