The rudder will need some major mods in order for me to interface them to the rudder gudgeons. I'm disappointed I wasn't able to make it work before the North Americans in Shreveport. Oh well.
The position of the pintles on the transom is the problem. The upper one is no issue - perhaps I could just replace that one? - the lower one is such that it's gudgeon will interfere with the rudder itself. Additionally, the old boltholes in the rudder head are too close to the position of that the new boltholes needed for the gudgeon. It would turn into an elongated slot. So what I think I need to do is to raise the position of the lower pintle and gudgeon - this could be good as it will probably reduce the amount of stuff hanging in the water creating drag.
