Roller trailer,boat loading problem.

[Bushwacker]

John, is your trailer the type that has a whole bunch of small rollers? I had the same problem with my Seafari on an EZ Loader single axle all-roller trailer which I suspect is a similar configuration to yours . . . it has 24 5" diameter rollers on 1" aluminum shafts, plus a center keel roller I added on aft X-member. I'm sure yours is a tandem and probably has even more rollers. Those trailers have so many degrees of freedom in the roller system that if the boat is not level side-to-side, it'll tend to come on the trailer the same way, so that may be part of your problem. I tried the heavy duty side rollers shown in this picture.
They were damaging the gel coat, so I had them raised so they contacted the rub rail. However I finally removed them because I discovered I didn't need them.

What I discovered was that the way I had the outer bank of rollers on rear X-member aligned relative to outer step of hull caused those rollers to properly align the boat before the side rollers even made contact with the rub rail! The trick is to set the rollers up so the outer group of rollers on aft x-member is lined up with the outer step on the hull, i.e., the inside edge of the outer rollers is just outboard of the outer step. As boat is coming on trailer, loading with a powerwinch, there is a pop as each of the outer rollers drops over the outer edge of the step. Once that happens, the boat comes on the trailer perfectly straight every time, regardless of cross winds, cross currents.

In this picture with boat a little further up the trailer, you can see that all 4 outer rollers on port side have already dropped over the step up to outer panel, so boat is now "locked in" and there is no way it can't come on the trailer straight. Notice that the side roller is not even making contact!

Haven't tried it with extreme imbalance on one side but I suspect it would still work. I have loaded it with port-side 15 gal baitwell full and it still loaded ok.

If you're able to move your rollers enough to get them lined up with the hull like I have, it should work. However I still have those side rollers, so let me know if you want to try them. Denny
