1977 Catalina 25 Standard Rig. Preparing for annual haul out/ bottom painting/maintenance. Have noticed the wood slightly dimpled on a couple of 4 bolts where the attach bolts go through the teak covered bulkhead and terminate on the other side of the bulkhead through the chainplate. This may be stress over a long period of time. Looks older and weathered to me. Plan on stepping the mast and adjusting the rigging during maintenance anyway. My sailing is very light and cruising type. Called Catalina Direct for tech support. They suggested, if bolt pattern was the same, buy two chainplates and have them modified (cut down) to put on the other side and reinforce the attach points (like a plate under a winch etc). Aside from the cost ($149 each) my bolt pattern is four in-line bolts on each side. Part from Catalina is a staggered pattern so will have to have made at a machine shop if I do this. The tech at CD said if I have it made it of SS it will need to also be electro-coated to preclude rusting. I would appreciate any similar experiences, concerns, or advice prior to doing this to strengthen this. Thank you.
