About the ISLANDER 40 MS
Re-introduced as FREEPORT 41. (1972?)
The Islander 40 MS is a classic American cruising ketch designed by Charles Davies and built by Islander in the USA, with production records indicating a build year of 1970. As a heavy-displacement vessel with a full keel, it represents a specific era of robust, traditional boatbuilding, though exact hull production numbers are not definitively recorded in the available data.
- Best for:
- This boat is best suited for conservative coastal cruisers and those seeking a stable, comfortable passage-making platform, given its high comfort ratio and heavy displacement.
- Bluewater capability:
- With a displacement of 28000.0 lb, a capsize ratio of 1.74, and a full/long keel, the Islander 40 MS possesses the structural integrity and stability characteristics necessary for offshore cruising.
- Comparables:
- Comparable vessels include other 1970s American full-keel ketches such as the Cal 40 or O'Day 38, which share similar heavy displacement, traditional hull forms, and masthead ketch rig configurations.
