Looks very nice… hadn’t thought about trying to use cardboard and waterproofing it. I wonder how it would do with Coroplast?
A fun looking Instructable where a Gavin Atkin Mouseboat design (plans are free from Duckworks) is constructed from builders foam insulation. Wouldn’t have thought it would be tough enough, but he skins it with glue-impregnated cloth and it seems to work well.
(I didn’t know people built camping trailers from this stuff… they call them "foamies".)
Oru Kayak has had some really neat, Coroplast kayaks for a while now. They are fold up into an easily transportable box that you can sling on your bike or whatever, then assemble when you are ready for the water.
OK, here’s a neat take on building a kayak… using 2" (or 1") EPS (expanded polystyrene) foam panels. Layer them like a cake and glue together, carved to shape. The builder calls it the Sawfish, and it looks like a fine craft.
And one that most anybody could build with minimal tools and space.
I do note that (like me), he finds that getting the supplies he wants is difficult. The standard local stores never seem to carry quite what you need (in his case 2" EPS foam), at least without buying a pallet of it.
Wooden Widget has added the Foldak, a 12 foot folding canoe.
The Foldak is an easy to build 12 foot folding canoe. Like the Fliptail it consists of a central keel, drop down floors, four hoops and a reinforced PVC skin. It unfolds in less than a minute and all the pieces needed to assemble it are always attached so you won’t arrive at the water’s edge missing a vital piece. It is stable, tracks well yet is easy to turn. Designed to be used with either a single paddle or a double kayak paddle.
We have specialized in Feathercraft folding kayaks since 1996 and have become familiar with SOAR inflatable canoes and Alpacka pack rafts since our move to Colorado in 2006. We regularly use these craft and the Kokatat dry suits and paddling gear we stock.
Our first-hand knowledge of these world-renowned portable boats and our commitment to provide you with personal, efficient service and factory-direct prices makes Folding Kayak Adventures your best source for Feathercraft kayaks, SOAR inflatable canoes, Alpacka pack rafts and paddling accessories.
We also carry Kokatat dry suits and watersports wear and expedition paddling gear, including four-piece paddles, life jackets, dry bags, safety equipment, and some camping gear.
