1: What track is that I see used for the selftacker in the picture (Ronstan?)
I think it is ronstan. And I have a ronstan personally and I'm fully satisfied with it. It certainly doesn't jam wioth sand and salt like the Harken recirculating ball rails. Hate those.
2: Why have they done the beam bolts that way? I am used to seeing the beam bolts go trough the whole beam, and compression pads inside the beams. I surmised this was the best setup for max. stiffness.
I thought/think that one of the stiffest setups is :
-1- inner bolts all the way through with a spacer in the beam.
-2- Outer bolts sunk into the beam with large filling piece between lower inside of beam and the head of the bolt. This piece must be of a material with a high compression resistance.
-3- Shaped beams (not round)
Of course the stiffest setup is the one used by the Blade F18. Stiffness on that boat is simply unbeleivable.
