Can it be loaded using the rollers and then be shifted up onto the beam rails?
Yes.
The trailer was originally a very stout steel Hobie 18 trailer I revised. Also, the beam rail supports can be adjusted if needed (eg stacking). I love the Trex material the rails are made of--it's that deck material made from ground up plastic and wood. It has the strength and workability of wood but the weather-resistence of plastic. And best of all, it is low friction--so the beams just slide across it without abrasion to the dolphin striker or beams.
