Captains,
You don't mind my reinventing the wheel, do you?
So, please just tell me why I'm wrong.
In my humble onion, a recurrent problem for beginner-builders is that we lack time to build a carvel marvel, albeit we pretentious mates loathe the quick, recommended hard-chined squatty remedy to this.
Could we make a hull out of 3mm (1/8") thick ply exterior panels? I've seen a Moth built that way, one end of the panel (or rather two of them) joined at the bow, and let free and large at the stern, to be closed by a transom.
Butt-jointing two such contraptions would make a longer boat. That would be four panels to make things simple, with two pointed ends, à la norvégienne (I'd want a small transom, but perhaps judging from some pics posted elsewhere some of you'd like it much larger :D ).
Two other layers would be added on the outside, a bit recessed so as to cover the midship butt-joint of the previous layer.
I think on that Moth there was only one layer, and a wealth of stanchions to hold the structure together, a bit like in Fireballs.
We'd have to mark all edges so that all layers would fit.
The panels should be shaped, convex sheer edges and slant short sides for the bow.
Would the amount of glue be expensive to the point of killing the advantages of the simple round-bilge construction device?
Would the center areas of the panels accessible to clamping during the gluing process?
Would steaming be necessary?
I know there's bendable ply, but it's hard to find and el expensivo.
