Wouter, I too like Eric Poulsen's ideas, like the capture of the striker rod (or strap), but I think the beam rails make it hard to ramp launch and load. I see that there are rollers down below so there must be a way to have it work either way, hull carrier or beam carrier. Can it be loaded using the rollers and then be shifted up onto the beam rails?

I also appreciate Kirt's comments, "According to Jim the worst "working" (he called it "racking") the beams/hulls go through is when the hulls are strapped down tight to trailer crossarms (regardless of whether you use rollers/cradles/etc.) since the trailer will flex while under way and this will "work" the beam/hull connection much worse
