The last picture in that set has a different tie bar set-up, which I have to say, looks far better than the way it's done in all the other shots. Do we know which setup was the new one, and which the old?
The pics showing it with a vertical post up to the rose joint looks really fragile to me, especially as it's farther forward along the torque tubes, so under much more load/leverage....horrid!
Looking around some other pics on that arnesson-industries site, I see they have a few pics of Brit boats, including the 'Broadstone Challenger' (Ice Marine 51') and Kim Collins's 38 Donzi on it's Hydrohoist.
Another tie bar picture that cought my eye, was this one. Don't think I'd want it showing me the way @ 150! Again, horrid amounts of leverage generated by the design. The class 1 cats running Arnessons always used to have hydraulic tie bars (needed to keep tie bar hardware out of tunnel view), don't really understand why you'd want to depend on a contraption like the one shown, when a tried & tested race system exists. Unless I'm missing something.
