I have a concern with bow to roller/stopper contact . . . when i power on I make contact with the roller/stopper then after i pull out the stern drops and the bow goes up so now a have about 2 inches +/_ between the bow and the roller. My big concern is if I leave it that way as I drive down the road the front half of the trailer will flex or bend up and down about an 1 inch or so which tells me sooner or later the front half of the trailer rails are going to crack open or brake off. Some body once said the the boat must be in contact with the roller so the boat and trailer become one unit. I realize that when the stern drops and bow will always go up some. If i pull out of the water enuf to drop the stern then I cant winch the boat forward . . . to much friction. Are my trailer rail flexing concern valid . . . do rails ever brake?
