21' Crab claw Catamaran
Description
The Crab Claw 21 is a rare, home-build-friendly plywood catamaran designed by Fred Shell of Shell Boats (Vermont), drawing inspiration from traditional Polynesian proas and catamarans. Introduced in the 1990s–2000s as a kit boat, it's a lightweight, trailerable coastal cruiser or daysailer emphasizing simplicity, shallow-water access, and the efficient crab claw (oceanic lateen) rig for light-air performance. Only a few dozen were built, making it a cult favorite among minimalist sailors.
