Re: Bunk or roller trailer
ab111 - you have the same center roller that I have, but I've never had a problem with boat jumping off that roller, probably because it only goes a couple of feet before the rear gangs of rollers that hang out behind the trailer start making contact. The marks on your hull indicate it's jumping off the roller after the first couple of feet. Don't think my vertical side rollers would help, as they don't make contact till boat is about halfway on trailer. On my previous boat/trailer, I had a couple of large rollers right next to center roller that were free to tilt toward the center and did a good job of centering hull as it came up on the trailer.
I suspect boat is jumping off the roller because there isn't much vertical load on it at that point. Are you backing the trailer in too far? Is the ramp so steep that the winch cable is actually lifting the boat up off the roller while ost of the hull is still in water? Or maybe a combination of these two factors? I back mine in just far enough that the towing eye, which is about 8-10" above waterline, is just above the top of the roller; roller and all but about 1/2" of cross member are OUT of the water. This puts enough load on that roller that tongue of trailer tries to lift bumper of truck when boat is about half way on trailer.
Hope this helps, Denny
