Yea as Nasher said, and upward pull is important. Its almost impossible to get air with towing on the D rings.
As for the issue with the force applied to the mountings, I see your point. I had thought about this. Wakeboard towers are usually only mounted at 4 points in the deck although I do wonder if the fiberglass is stronger in the topdeck of hard boats than the deck of a rib?
I thought perhaps have 4 mounting points, 2 as rear as possible (possibly also bolted to transom as i assume that is stronger than the deck?), then 2 as far forward as possible without intruding in the passenger space. Then I figured having a plate bolted in several places along the deck between the rear and front mountings with the frame welded/bolted onto that would spread the pressure out more?
This style frame would allow the mountings to be spread further whilst keeping the actual frame behind all the seating.
