I think you guys have missed the most important reason why the bridle tangs are so low. The lower you want set the jib on a formula eighteen the shallower the bridle becomes - unless you place the fitting much lower down the inside of the hull.
We did this on the blade formula eighteen - yes we got the idea from the capricorn and acknowledged that they were on the right path.
We placed the fitting about one hundred mm down from the gunnal and reduced the load on the hulls, bridle etc.

It will be interesting to see how the new nacra will go against the capricorns and tigers.
