There is a condition called "Cupping" that happens to boats on trailers. It's when the hull, just forward of the transom, for the first several feet going forward is actually pushed upward over time and the fiberglass takes on a "set".

Older boats (Because of their age and the number of hours spend sitting on a trailer) are more susceptible to it than brand new boats. Most times the condition is not reversible. The condition causes a loss in performance of the boat and reduced control of the boat at speed. It is caused by the boat sitting on a trailer where the rear of the hull hangs over the end of the support (Bunk or roller) by a few feet, and is further aggravated by the weight of the engine bolted to the transom. That's why it's important to make sure that the last roller or the end of the bunk is right at the edge of the transom or, at most, only a few inches in front of it.
