Backpack 38

Designed by Dudley Dix

An 11.6 m (38 ft 1 in) demountable cruising catamaran by Dudley Dix, drawn as his take on the simple Polynesian style of cat for low-cost tropical cruising. Overall beam is 6.5 m, displacement 4,000 kg and draft 0.85 m on shallow keels. The beams lash or bolt to the hulls so the boat can be taken apart for transport. It was first planned in single-skin GRP, with plywood plans drawn for amateurs.

Dix's page says the design is no longer available and is kept only as an example of his work, and that the plywood bridgedeck and rudders were never fully detailed. A simple plywood cat of this size would still be a rough 5,000 hour project. Measured medians from build logs appear below.
