The Incredible Paper Canoe

I had the (perhaps) dumb idea about making paper mache boats after doing some research on paper mache racing shells (http://en.wikipedia.org/wiki/Papier-m%C3%A2ch%C3%A9).
From the first couple of experiments with paper, I found that the material was pretty strong and light, so I made a canoe out of it!
Using several pounds of homework from last semester school, I created a super awesome canoe!

Why paper?
Since it's light, cheap, and flammable (but don't light it)!

Step 1 How the boat works

The canoe is basically super strong paper mache that was shaped by a mold.
I built a mold first and put paper on top.

What you need:
Lots of paper (stuff that soaks up water)
Waterproof glue and flour
Water
Vinegar
Scrap wood (more on what kind on the next step)
Mesh or strips of something flexible
Epoxy, glue, or paint for waterproofing

Sorry no pic.

Great boat!
A couple of thoughts for your next one.
Structurally the boat gains most of its strength (for resisting folding up under your weight) from the vertical sides of the boat, so the thicker and taller you make them, especially in the middle the stronger the boat will be.

If you look at how surfboards and many kitplanes are made, they make the shape out of some kind of stiff foam (urethane or styrofoam, it does not matter for this) and then cover the foam with a thin hard shell, in their case fiberglass and in yours paper mache'. The benefit of this is that the thickness of the foam allows the hard shell to simulate a much thicker hard shell without the extra weight because most of the stress is carried on the outside edges of the shell and not by the foam. The foam helps keep the shell from buckling by giving it a stiff stable base to stick to.


Good luck on your future Paperventures.

Not bad at all. Good idea about using window screen as reinforcement. I think I.d put a bit more wood into it, keelson ,gunwales and some ribs . It'd help maintain the shape.

tres cool! mui excellente'! I like it! I'll suggest this to my students...a great motivator to get them to put something on paper!

[LeonArchiTesla]

got any bamboo handy? use strips for your frame...you could even shred it to add criss/cross with the papier mache and strengthen it further...might preclude you having to use cross braces later on.

try a 'release' layer of plastic cling wrap first so you don't stick!

Great project!! I hope you get to paddle it soon

We definitely need to see this in action, preferably a video of it's launch and first use.

Expect failure ;)

I expect comedy!

[ANDY!]

I shall do that as soon as I can!

thats awesome ! check out some of my "ibles" I use a paper mache made with acrylic paint, it dries very hard and virtually waterproof by itself

Great job, congrats!
