Call Steve at AES Manufacturing in Chattanooga. If hes not too busy, he may be able to help. I could but I'm running with a low crew and a surge big orders right now.
Should be fairly easy though. 2 Beams for the frame bend to a tongue and hitch. Couple of cross members with short boards to cradle the bottom, maybe a set of boards along the side just to steady it from side to side. Trailer frame wouldnt have to be but a few inched wider than the widest part of the canoe.
