Serenity Catamaran
Description
The Serenity is a folding beach catamaran designed by Ray Mack in 1974, offered as a plans-only plywood kit for amateur builders through the 1970s-1990s. Likely dozens to low hundreds were constructed worldwide by homebuilders (exact quantity undocumented), featuring innovative aluminum-frame folding mechanism for trailering (fits in a car trunk), symmetrical hulls, trampoline deck, lateen sloop rig, and kick-up boards/rudders—perfect for portable fun on lakes or beaches. Key features: lightweight (150 lb), quick setup, stable for 2-4 sailors, and durable epoxy construction.
