Hi Luckybalboa, that's an interestiong idea. The freight is around $500 so it would be interesting to see what it would cost to get a couple of good tubes sent here and get a frame welded. The only real issue I can see with this is that there isn't an established industry here making Pontoons - so I'd be relying on a fabricator to (I guess) copy something from pictures. Worth having a talk too them though. Good thought, thanks!
