I'd advise against supporting any bolted boat by the beams. When you fly a hull the hull is pushing up on the beams not bouncing down a road hanging off them. Hanging the hulls on the trailer will definately soften the composite structure around the beam landings and shorten the competitive life of the boat.
A's can do it because they're A. light and B. Glued.
Never had a problem with my bolted Taipan over several thousand miles on my beam-supporting trailer. I would check the bolts from time to time and they were always torqued as expected. Also, the boat is as stiff today as new.
