Re: Pontoon fabricators
Toons are very difficult to weld, and they're too important to do half *****ed. The aluminum must be rolled into a tube on circular toons. The U shaped foam filled pontoons are easier to build, but seldom seen any longer.
I know it's a long way to Edmonton from anywhere, but for simplicity sake, check with UFab in Ontario. From time to time, they may have a truck going west.
You can find some toons online, however many have small dents or scratches--seconds. But some are good buys.
Great Lakes Skipper in Racine, WI (south of Milwaukee) often have toons for sale.
T&M Marine, the largest pontoon/tritoon dealer in North America, carries toons, and they're located due north of Minneapolis.
The rest of the toon brokers are in northern Indiana--around Elkhart. You can sometimes spot them online.
Your other option would be to buy another pontoon for their toons and swap them over.
