It would seem that a person could use the plans for any of the myriad of 
stitch-n-glue boats - and use aluminum instead of the plywood - and 
wirefeed welding for the seams instead of epoxy.  AL is very easy to work 
with fairly normal woodworking tools.  Even if you couldn't find a welder 
willing to (or cheap enough) you can purchase a decent wirefeed unit set up 
for light (up to 3/16") AL for ~$700.  If you built a couple of boats for 
you and a friend it would seem cost effective.  AL stock is not that 
expensive - for the quantities needed to make a kayak.

Learning to put down a decent wirefeed bead isn't magical or 
difficult.  Probably a couple of lessons from the shop where you buy the 
welder would get you going.  The hardest part would seem to be forming the 
cockpit coaming and hatch openings.  But certainly solvable problems I 
think.  Due to the high heat conductance of AL, the temp of the water would 
pass through the boat more readily.  Might be a cold ride in cold water 
conditions...but in the summer it would be a great A/C unit.

Hmmmmm?  This is something to seriously consider.  I'm anxious to hear from 
someone about why AL wouldn't be a good choice.  I guess I'm also thinking 
about someone like me (landlocked in WI) - who paddles freshwater.  The 
salt water corrosion issues wouldn't be a concern.

Anxious to hear more.

Kirk, sorry to hear about the arm.
