Well I decided to piece the boat together and just sail her for the summer. I'll tackle hull repair next fall or winter. The wood in the aft hull seems good enough to hold tiller parts so off we went. However we are having trouble keeping the rudder down in the water. It wants to come out of the lower bracket and come up out of the water. We have the thumb screw tightened pretty tight on the top plate so I'm wondering if there is some thing else going on. Is this space supposed to be there? The rudder moves a good half inch up and down in this space and I thought maybe that might be contributing to it coming out of the lower bracket.
