Unfortunately the haul and survey would have driven the boat to the point of being unaffordable at the moment. I did the best I could based on the suggestions here and a few other places (especially the Catalina forums).
Fortunately, I was also able to track down the owner prior to the person I bought from, and he was able to give me some pointers as well. While only time will tell, I don't think there are any showstoppers.
Now to hunt for insurance!
