My father in law and I have the same exact trailer and have the same prolem. The winch strap likes to curl up and get all knarly after a season of use. The boats track straight up the trailer but they still always seem to veer off one side or the other. The problem might be in the design of the winch post or stand. it is angled forward towards the bow and the winch mounted so the strap has to go up and over a tiny cheesy roller just below the bow roller. I have seen winch stands that the main post is angled away from the bow with another bracket going forward which holds the bow roller. Then the winch is mounted horizontal and pulls the strap level with the boat under the bow roller. That seems like a better design than what we have. Anybody have any thoughts on this? Is there something we are missing in the equation here? Can you build a stand or should or would we be better off buying one pre-made? This is driving us nuts!!
