Thanks for the quick reply. For the centerboard, I have water on the port side of the centerboard bolt/pin which is the only place water could have come from. I had the boat out on Sunday for 4 hours. When we docked I noticed more water on the cabin floor than before we set sail. I had some water in that area throughout the winter months and it stayed at the same level until I took it sailing on Sunday.
For the rudder, thanks. I will try loosening the bolt/nut a bit. I was afraid by doing this that the rudder would come up on its own while sailing.
