I had a chance to switch the trailers today with a friends that just happens to fit this boat. I moved the bunks farther out to the outside chine because the trailer is so much wider then my float on.

The boat centered on the trailer well but the bunks are straight and there is only about a foot and half resting on them. You might be able to see it in this picture.

I never noticed the hull having that much curvature
I am having second thoughts on the old trailer.
Everyone keeps telling me how good and strong the old float ons are but it looks so small compared to the magic tilt trailer it is on now temporarily.
