Plans to build the 8' BackBay Ultralight Boat

Back in my commercial fishing days when I was in college, I was leasing a 36' Albacore and Rock cod boat and needed a dinghy to use while in anchorages. I picked up an old, flat bottomed pram that needed some work for, I think $10, and glassed the bottom to fill some holes, and painted it up the same color as my bigger boat. It proved to be a superb little dinghy and I rowed it often while in anchorages, and to cross over the bay when in home port when I wanted to dig up a few clams for dinner. I really loved that little boat and it sure served me well. Here's my version of that very same little boat. The modern stitch-and-glue construction means this little boat is substantially lighter than my old framed and glassed over tender, and that one was easily handled. All it takes is two sheets of 1/4 mahogany ply, a few scraps of 3/8 ply, and a couple of moldings to build the Back Bay. All are available at any warehouse home center now just about everywhere in the US. It rows great, but if you're of the couch potato persuasion, you can mount a little 1 to 3 hp outboard on it and putt along quite nicely.

About Ultralight Stitch and Glue Boats

The Stitch and Glue boat construction technique, evolving over past thirty years or so, was simultaneously developed by a number of innovative boat designers. The technique resulted in simple, easily built boats with beautifully sweeping lines and light, tough construction. These plans include all dimensions for all parts of the boat and easy to follow instructions for assembling the parts. These boats go together without any jigs or fixtures, so anyone can build one in your garage or back yard. Many are little more than a dozen to twenty hours of work.
