My rocket trailer fenders were very flimsy, as are the support brackets. One was bent a little. Then I stood on it getting into the boat and it was bent a lot!
I took off the fenders (aluminum diamond plate by the way) and cut 2x10's to the right length. They fit right in between the lips. I painted the board black, drilled the fender and bolted the board in place from the top with a pair of lag bolts every 12". The bolt heads don't look bad imo. I re-installed the fenders 1 1/2" higher to keep the tire clearance the same and filled the bolt holes with dummy bolts. I bolted the supports on with lag bolts. The 1/4" or so that extends below the fender really isn't noticeable being black.
Now the fenders are straight and will hold 2 people.
Just thought the rest of you with these trailers might have the same problem.

See other threads on Rocket trailers. Not the best liked trailer made. I personally did not have any problems with them but I know many others that did.

Glad to know someone knows how to make them work.

Are these Rocket Miami trailers or Rocket Trailers?

probably the Rocket out of Ft myers Fl, I also have a flimsy fender special...... cheap junk
