The San Juan 7.7 is a compact, performance-oriented fractional sloop designed by Don Clark and built by Clark Boat Co. (USA) in 1979. With a displacement of 3200.0 lb and a beam of 9.5 ft, this single-year production model offers a lightweight, responsive sailing experience typical of late-70s American designs.
- Best for:
- This boat is best suited for coastal cruisers and weekend racers who prioritize speed and ease of single-handed handling over heavy offshore comfort, given its light displacement and fractional rig.
- Bluewater capability:
- With a capsize ratio of 2.58 and a comfort ratio of 11.35, the San Juan 7.7 is primarily a coastal cruiser rather than a bluewater passagemaker, as its light displacement and fin keel prioritize performance over heavy-weather stability.
- Comparables:
- Comparable boats include the Cal 25 and O'Day 25, which share similar fractional sloop rigs and light displacement characteristics, making them direct competitors in the 25-foot performance cruiser segment.
