Bottom job
The boat yard here in Oklahoma City charged me $650 for a complete bottom job which included blasting off the original coating, checking for damage, repainting boat, rudder, and keel. For this money they also had to drill out one bolt on the swing keel and replace 2 bolts. The price also included a complete inspection of the top side rigging. Since I had just bought the boat, I was extremely happy to pay a professional to do a nasty job and check everything out for me. They have the hoist to get the boat up where you can get to everything and have done hundreds of Catalina 22's. I am not sure what just the paint removal and replacement would have cost. I do know that the bottom paint is well over $100 per gallon and it takes several gallons to do the job. They got the water line correct also.
