It is generally difficult for even a good welder to fabricate a boat out of
light aluminum; figure on 1/8" plate, or thicker. This material weighs
about the same as 3/4" plywood. Figure 200 lbs or more for a canoe. At $2-3
per pound...

There are plenty of plans for plywood canoes which should work, both being
"sheet goods". Sleway-Fisher is one firm which sells plywood canoe plans.
You should be able to get some ideas from their webiste. Usually with
plywood canoes there is a fair amount of material cut to waste. I
think plywood is relatively inexpensive compared to aluminum so that might
be an issue.

What are the pro-and-con considerations of making a canoe out of eighth-inch
plywood, perhaps laminated prior to assembly with light 'glass and epoxy
pulled down with a vacuum pump? Will the combo of plywood and glass be about
the same weight as quarter-inch ply?
