Reads scarey Roy. I too have experienced the boat trying to sail over me,usually as I am trying to scale the main beam. I have a similar righting system but have a loop/bowline at each end of the righting rope. I hook my trap hook into the loop, as you do the ball. Never been a problem. Capsized three times several weeks ago and required assistance on the third total inversion. The extreme force on the system applied by the gunned power boat bent the pulleys at the corner of the tramp and main beam but the bowline did not pull through the pulley. Replace the balls with a loop and stopper knot.
