My present dinghy, an Eastport Pram, weighs about 75 pounds, so this new one should be a lot easier to lift on deck. The Eastport Pram costs about 1/2 knot in boat speed when towing, so maybe the new 'Fly will tow more easily!
There is also a Yahoo Group for Geodesic AiroLITE Boats.
Before I started to build, I read over the plans and instructions carefully. The plans included full-size layout half-templates for the building frame stations. The plans were tacked over a 1/8" piece of plwood, and very small holes drilled at each point along each building frame station (and the transoms), then the 'dots' joined, showing the frame outlines.
The plywood template was used to layout each frame, left and right from a drawn centerline on pieces of 1/4" plywood. The plans called for using heavy cardboard, and a cardboard / wood box beam 'strong-back' to set up the frames. But as I had lots of old 1/4" plywood I used this for the frames, and an old 6" x 6" fence post for the 'strong-back'.
This worked amazingly well, as the box was minimal in size, and heated easily. A couple of ribs got overheated and were more like a wet noodle than a piece of wood! The 1/4" x 1/2" x 24" ribs cooled really fast, so it was handy having the box right by the boat. As soon as a rib came out of the box I bent it by hand, then slipped it into place inside the stringers, clamping it in place with 2" pieces of slotted 2" ABS pipe, and some cable ties when the pipe ran out.
After the ribs had dried somewhat, Gorilla Glue was used to glue them to the plywood bottom, the stringers, and the gunwale.
The next step is to clean up all the glue joints, fill any holes, and coat all the wood with epoxy, while I wait for the Kevlar Roving to arrive. As it was only ordered today, there'll be lots of time to get all the detail work done. There're quite a few little bits and pieces that need making too, as well as the seat frames.
Platt's drawing calls for the main thwart a little too far forward for my liking. Comparing the measurements to my Eastport Pram (very similar in size), if I move the thwart aft by one rib it should be perfectly balanced with one person aboard. I'm not sure if I'll install a forward rowing position yet, maybe later. Looking at Maury Maden's 'Fly in the picture at the top of this post it appears he also moved the main thwart aft by one rib.
