About the ISLANDER 48C
Also sold as MARINER 47. Thanks to the designer, Ted Brewer for providing corrections. Originally offered as a sloop or cutter.
The Islander 48C is a rare, heavy-displacement cruising yacht designed by Ted Brewer and built by Islander Yachts (USA) between 1982 and 1985, with only 6 hulls constructed. Its substantial build quality and limited production run suggest a focus on durability and performance over mass-market appeal.
- Best for:
- This boat is best suited for experienced coastal and offshore cruisers who prioritize seakeeping and comfort, as indicated by its high comfort ratio of 33.91 and heavy displacement of 29125.0 lb.
- Bluewater capability:
- With a displacement of 29125.0 lb, a low capsize ratio of 1.8, and a fin keel, the Islander 48C is well-suited for bluewater cruising, offering stability and safety in offshore conditions.
- Comparables:
- Comparable vessels include other Ted Brewer designs from the early 1980s, such as the Islander 36 or 40, which share similar heavy-displacement characteristics and cutter rig configurations.
