Seaclipper 34
Description
The Seaclipper 34 is a plywood demountable cruising trimaran designed by John Marples (of Searunner fame) in the late 1970s/early 1980s as an "economy cruiser" for offshore passages and extended coastal voyages. Part of the Seaclipper series of affordable, home buildable multihulls, it features a simple sloop rig, folding/demountable akas (crossbeams) for trailering or storage (under 8 ft beam when disassembled), and a focus on stability, speed, and ease of construction using stitch-and-glue plywood/epoxy methods. With standing headroom in the main cabin and an optional aft berth, it's suited for couples or small families seeking a lightweight (under 6,000 lbs) bluewater-capable boat without the complexity of larger tris. Fewer than 50 were likely built due to its niche appeal, but survivors are prized for their performance and simplicity
