I'm looking for some help with plans to build a trailer for four OC6 canoes. Does anyone have any pictures of a trailer, plans or trailer designs, or even any advice on where to look on the internet. I recall seeing a pretty cool trailer in Kauai which could carry three (or four?) canoes on the bottom, and then two brackets that fitted on to it to enable another four to be carried - like a double decker. Any help would be greatly appreciated.
