Despite efforts, I can't find a suitable trailer, so I'm going to have one custom made for my 14 x 6.6 NRS raft. What I'm telling them:
-a 14x7ft platform made of marine plywood to prevent overhang of the 14x6.6ft raft
-roller on the back
-14-15 inch tires for my drives to the Rockies
-D-rings on the side to tie down frame
Does this sound good? Anything I'm missing? Are these tires too small for long road trips and lumpy roads?
I think you pretty much covered the necessities. This is my only input: I just bought the 14' NRS Outlaw and and already had a 6 × 12 deck over utility trailer It has at 8" front rail but with the rocker of the boat it fits great. The bow of the boat sits perfectly on the front rail and even though the sides of the tubes do over hang a little I still have 3" on plywood showing on each side where the tube sits on the deck and about 1' at the bow and stern. Hope this helps. It is nice to have a narrow trailer in many in many of the places I tow mine.
I like it. Carvedog, had the idea to use a car cover.
I've tried to travel with it, but Bernoulli's principle balloons the top up. I've tried adding straps and stuff and finally got it to stay taut. But, then it was a pain to let air out or get into the raft for any reason. Now, I travel without it on.
I wish there were cut outs or pouches for oar towers though
