After a couple of quick phone calls...some food for thought on the AL kayak 
idea:

Lightweight AL canoes use .040 AL skins.  Std AL canoes use 0.50.

.050 AL sheet costs between $3 and $5 per sq ft - didn't get a price on .040.
.050 AL sheet weighs .72 lbs per sq ft.  .040 weighs .57 lbs per sq ft

So...going on absolute guesses here....and maybe someone can correct the 
assumptions but....

Let's say we used 8 panels of AL sheet for the hull and deck - each 12" x 
10' long
	(no idea if this is realistic - but seems like it MIGHT be close??)
The weight of the skin only would be between and 45 and 57 lbs depending on 
thickness.

The cost of the skin (materials only) would be between $250 and $400.

Not sure if this sheds any light on the subject or not...but FWIW...
