Some neat plans for some nice looking boats and some other things (can you say toy airplane pedalcar?).
Check it out… pretty cool.
Another one that I somehow missed when I was doing the Skin on Frame posting.
Thomas Yost has a very detailed and picture rich web page showing the different Kayak designs and how they go together. His designs revolve around HDPE (high density polyethelene) frames (or cross sections, as he calls them) with aluminum tubing. Ove r that goes the PVC skin.
Links to various suppliers of these materials are provided.
There is a method of building that I ran across recently that has been popular for many years in the canoe/kayak world… skin on frame. Its a matter of building a lightweight framework from wood/metal/plastic and stretching a skin over it. The flexible skin becomes the hull.
Fascinating to look at some of the ideas of work. This is all a bit smaller than I’m interested in, although it fits in some way with the Origami Dingy that I’m (slowly, I know) working on… some of these kayaks use the same material as specified for the dingy.
I can’t help but think there may be some applications for these skins on larger craft… not as a self-supporting hull, maybe, but as a "coating"? Heat shrink a skin onto a wood backing instead of epoxy? Worth some thinking/testing/playing.
Anyway, here’s a collection of sites for those interested:
