About the ISLANDER 37 MS

Same hull as the ISLANDER 37. These boats were also available under the Yachtcraft brand as kits.

Sailpages Buyer's Take

The Islander 37 MS is a robust cutter-rigged cruising yacht designed by Bruce King and built by Islander Yachts (USA) in 1974. With a displacement of 14900.0 lb and a comfort ratio of 30.75, this vessel is engineered for stability and seakworthiness, though the exact total hulls built remains unconfirmed in available records.

Best for:
This boat is ideally suited for coastal and offshore cruisers who prioritize a stable, comfortable ride over high-speed performance, particularly those seeking a cutter rig for versatile sail handling.
Bluewater capability:
With a low capsize ratio of 1.76 and a high displacement-to-length ratio of 268.27, the Islander 37 MS demonstrates strong offshore suitability and resistance to capsizing in heavy weather.
Comparables:
Comparable vessels include the Cal 3-36 and O'Day 36, which share similar displacement ranges and full-keel or modified fin configurations from the mid-1970s, offering comparable interior volume and cruising comfort.
