Aqua Cat 12
Description
The Aqua Cat 12, is a lightweight fiberglass catamaran sailing dinghy designed for recreational day sailing and one-design racing. Produced by American Sail Inc. (formerly American Fiberglass Corp.), it was introduced in the late 1960s and built through the early 2000s, with modified versions available until at least 2003. This 12-foot, 2-inch (3.71 m) catamaran is trailerable, beach-launchable, and ideal for beginners, families, or solo sailors on lakes, ponds, or calm bays. It features a boomless single-sail rig on a tubular "A-frame" aluminum mast, eliminating standing rigging for safety and simplicity, and dual transom-hung rudders for precise control. With a capacity of 2–3 people (up to 800 lbs.), it's stable and easy to handle, capable of planning in moderate winds but not suited for rough seas or offshore use due to its small size and open design. The Aqua Cat 12 was once the world’s largest one-design catamaran class before the Hobie 16/18 surpassed it, with thousands built, making it common in the used market. Owners praise its quick setup (under 15 minutes), portability (cartoppable), and forgiving nature, though older models may need hull repairs or sail replacements due to age. American Sail Inc., founded in 1976 by David Stanton, continues to support parts and sails. This model is distinct from the larger Aqua Cat 14,
