He was after a handmade Kevlar whitewater canoe so a light and tough canoe but nothing compared to your Grumman .He was in the prairies when he contacted me ,and specifically asked about using it on a certain river known for whitewater fun ,so I honestly assumed he was not going to use it on his way there as well .
There is a company in Guelph Ontario that builds a canoe trailer for about $200.00 Canadian that looked like it might fit the bill for him ,I thought that was pretty inexpensive for a very specialized accessory .
