trailering by them beams is increasingly popular because it protects the bottom of the hulls. However....

The foward beam-hull connection is designed to be in compression and shear, when you hang the hulls off the beam this puts the whole thing in tension. With a 30kg+ hull hanging from this joint and vibrating as you go down the road at 60 mph you are definately softening/fatiguing this crucial area, particularly an issue with a polyster boat.
