Well, there is turning over your pintles....
My 34 year old Cal Fuller A-cat (see avatar <=) has them on the other way, and have only come off once, after crashing while doing the Wild Thing, fortunately just on one side: I had failed to put the curl pin on that side, and the spring thing bent somewhat on the other.
I have run a spinnaker on this boat too, as well as the hydrofoils. Imagine the up load with lifting foils on the bottom of my rudders.
