About the HARPOON 5.2
An open cockpit version was also available without the cuddy/cabin.
The Harpoon 5.2 is a compact, high-performance daysailer designed by C&C Design and built by Boston Whaler (USA) between 1977 and 1983, with a total production of 1700 hulls. Its lightweight construction and fractional sloop rig prioritize speed and ease of handling over heavy cruising comfort.
- Best for:
- This boat is ideal for coastal day-sailors, couples, or single-handers seeking a trailerable, performance-oriented package that is easy to launch and retrieve. It suits owners who prioritize sailing dynamics and low maintenance over long-term offshore provisioning.
- Bluewater capability:
- With a displacement of 565.0 lb and a comfort ratio of 3.82, the Harpoon 5.2 is not designed for bluewater cruising and is best restricted to protected coastal waters due to its light weight and narrow beam.
- Comparables:
- Comparable boats include the C&C 27 and O'Day 23, which share similar fractional sloop rigs and trailerable footprints from the late 1970s. These vessels offer similar performance characteristics but often feature heavier displacement and different construction methods.
