If by "roller trailer" you mean the old-style floppy roller trailer in which a dozen or more moveable rollers support the weight of the boat, then the general answer is that style trailer is should be avoided with Boston Whaler boats.
For more information on trailering a Boston Whaler boat, visit the REFERENCE section and read the several articles in the TRAILERING section. See

The principal concern is the hull of a Boston Whaler is constructed with a unique method--the Unibond Hull method--and the hull laminate layup is relatively thin, except at the keel. Most of the weight of a Boston Whaler boat kept on a trailer should be supported by keel rollers, or a combination of keel rollers and bunks. Boston Whaler used to be quite emphatic about this approach, but at some point they seem to have stopped insisting trailers must have keel rollers carrying most of the weight. The floppy-roller trailer design has never really been used or blessed by Boston Whaler. The concern is that too much force could be concentrated on a small area and possibly cause a deflection of the hull laminate.
