Well, it's done. Survey went well, didn't find any major issues. The sloppy rudder turned out to be just the loose tiller head. There was a little bit of play in the rudder itself when the boat was hauled out, but not excessive. There was also a good amount of blisters (about 100-150), but they were small, about the size of a dime, and the surveyor advised not to worry about them.
So, now I just need to get the boat to her new home across the bay. That should be an interesting experience for a first sail
Thanks for all your help guys, it was much appreciated.
