About the A CLASS CATAMARAN
The A CLASS CATAMARAN has undergone a steady evolution since the rule was first established in 1962. Dimensions listed are class limits, and beyond these few restrictions, the class is fairly open.
The A Class Catamaran is a historic 18.0 ft racing catamaran designed by an unknown designer and built in 1962. With a hull count of unknown, this lightweight vessel features a rotating spar rig and a displacement of 165.0 lb, reflecting its origins as a high-performance day sailor rather than a cruising platform.
- Best for:
- This boat is best suited for experienced day sailors and racers seeking a high-performance, lightweight experience on protected waters. It is ideal for enthusiasts who prioritize speed and agility over comfort or storage, given its minimal displacement and lack of reported cruising amenities.
- Bluewater capability:
- With a capsize ratio of 5.49 and a displacement of 165.0 lb, this boat is not suitable for offshore or bluewater passage making. Its design is strictly for inshore racing and day sailing, lacking the stability and volume required for open ocean conditions.
- Comparables:
- Comparable boats include other 1960s racing catamarans like the Nacra 18 or early Hobie Cats, which share similar beam-to-length ratios and lightweight construction. These vessels are comparable because they prioritize planing performance and windward ability in light to moderate winds.
