13 foot simple cruising sailboat for two overnight, designed for protected or inland waters.
A very easy and cheap to build pocket sailboat with a cuddy cabin for two and a small cockpit.
8 sheets of ACX 3/8" plywood.
I recommend using epoxy, without glass fiber, on the bottom of the hull, chines and all edges.
The plans detail all the dimensions of the parts, how the parts nest on plywood sheets, a complete building sequence in 3D and some detail pictures.
The junk rig sail is a major part of the design, with a hinged batten system that improves performance to windward.
