Re: Keel bolts
Re C27 keel bolts, they are a weak point, just plain steel on mine and all are rusted and one broken off!!! The factory has a solution for the problem though. They recommend drilling new holes and installing lag screws. I think they specify stainless but I chose to use galvinize steel on my own boat (there is a reason).
Re the galvinize bolts - it's because stainless steel in a salt water enviroment without air can corrode and fail.
See Nigel Calder's "Boatowner's Mechanical and Electrical Manual - Third Edition.
The factory will send you the repair info on request. (+1-727-544-6684 Catalina Yachts)
Good luck and have fun sailing the boat.
