Cross 46-2
Description
The Norman Cross 46 Mk II Trimaran (also known as the Cross 46 Mk II) is a custom-built American folding trimaran sailboat designed by multihull pioneer Norman Cross in the early 1980s (plans dated ~1982). Primarily a plans-only design for home or professional construction using cold-molded plywood-epoxy methods, it's one of the largest in Cross's series, with very few units completed (estimated 2–5, including a well-known 2001 German-built example). It features folding amas (outriggers) that collapse alongside the main hull via stainless hinges, reducing beam from ~24 ft to ~8 ft for trailering. Designed for unlimited ocean passages, coastal cruising, and family adventures, it offers responsive performance with a spacious interior, but its vintage design makes it wet in chop compared to modern tris like the Corsair F-41 or Neel 45.
