A nesting dinghy design by Danny Greene
The plans contain 8 sheets of 11" x 17" drawings, a 22" x 30" lines drawing and a 30" x 70" set of full size patterns for bottom and side panels. There is also a 12 page building guide.

I have been designing and buliding nesting dinghies for more than ten years. The primary reason that I have been concentratng on this type of boat is that I have, at the same time, been living aboard. and cruising on small sailboats.
In 1977 I cruised to the Caribbean on my 28 foot cutter, FROLIC, and carried an inflatable dinghy and an outboard motor. First I tired of the noise, mess, smell and expense of the outboard motor; then I tired of the uselessness of the inflatable as a rowboat (not to mention it's vulnerabllity to damage and theft). In 1979 I designed and built TWO BITS, a two-piece nesting dinghy built of plywood and epoxy resin, using the "stitch and tape" construction technique.
TWO BITS was about 9-1/2 feet long, 4 feet wide, and stowed in five feet of length. She served me well, and I sold hundreds of sets of plans for her. Over the years, I experimented with various other dimensions, hull shapes and construction details. I tried boats up to 16 feet in length and with two and three nesting pieces. Some towed beautifully, some sailed very well, some towed well, some were stable, some handled rough weather easily, some were light and compact to stow and some were very easy to build. None, however, combined these qualities in a way that satisfied me, until CHAMELEON.
Surely there are small boats that can outperform her in one or two areas, but I do not know of any that have these same all-round performance characteristics that make CHAMELEON an ideal tender for a cruising boat. She is, as well, a very attractive multi-purpose boat that can be easily transported by one or two people and stowed in a very small place.
CHAMELEON's two poeces can be assembled and disassembled in the water, so it is possible to launch and retrieve her one piece at a time. Each piece weighs approximately 50 pounds. There are built-in buoyancy chambers in the stern quarters and a foredeck locker that could be left sealed for buoyancy, fitted with a watertight hatch, or fitted with a "water-resistant" plywood hatch.
As a rowboat, CHAMELEON features two rowing positions, so she can be proberly trimmed with one, two, or three people aboard. Oars of about 7-1/2 feet length seem to work best. Safe capacity is about 500 pounds. For those interested in fitness rowing I have designed a sliding seat/outrigger option that is inexpensively built of plywood and allows use of 8-1/2 to 9 foot oars.
CHAMELEON is built in the "stitch and glue" plywood/epoxy technique. The plywood panels are cut out from dimensions provided in the building plans (or from full sized patterns) and fastened together using copper wire and nylon fishing line. There is no strongback or building jig required; the hull is both self-supporting and movable during construction. Thus it can be worked on outdoors if desired, and moved inside (or covered with a tarp) at night or in inclememt weather.
After the panels are assembled into the hull shape, a thickened epoxy fillet is applied to all the inside corners, followed by two layers of figerglass cloth tape and epoxy resin. The the outside corners are rounded and taped. Next the entire outside is sheathed in cloth and epoxy and the other constuction details are completed.
Though CHAMELEON is intended for the amateur builder, she is not an extremely easy boat to build. The number of details involved in making the two-piece nesting dinghy make it nearly as much work as building two dinghies. Some previous boatbuilding experience, or some previous experience working with epoxy resin, would certainly be an asset. Yet, I think that a very handy builder, with some assistance (in the form of an experienced friend or some reverence material on "stitch and glue" construction) could successfully build CHAMELEON.
Tools required to build the design include a table saw (or access to a table saw), electric saber saw, electric grinder, drill, hand saw, wire cutters, pliers, hammer, screwdriver and about six clamps (3" or 4"). The basic materials for the towing version are 3 sheets of 1/4" exterior (or marine) plywood, three gallons of epoxy resin, figerglass tape and cloth, and two fairly clear spruce 2x4's, 12 feet long. The sailing version requires one additional sheet of 1/4" plywood, another gallon of epoxy resin, and two more 12 foot spruce 2x4's.
