I would strongly suggest foregoing rollers and install bunk-boards. They are much easier on the hull. I did this for M-15 after spotting some deformations in the hull from my rollers. This is an Arizona boat so heat and weight didn’t do the fiberglass any good.

The trailer currently has the standard tapered type. I’m thinking of switching to a flat type that the keel might set more squarely on.
