I think you raise a good point. The rudders and associated hardware are not designed for going backwards. Maybe if the rudders are largely out of the water and pointing straight up at the start, and one is able to get the back of the tramp to plow down into the water, the stresses would be short lived.

I guess the real question is what is the best way to right a boat with a power boat? Which system puts the least stress or risk of damage on your boat? I know you can damage your hulls if the rope comes across the side and you incorrectly pull with a power boat.

I really don't know...(but am unafraid to speculate).
