Thanks for the info. I'll be looking at a 1968 model as well as a hull in the 700s this weekend. The keel bolts are the first thing I'll be checking on the older boat

You are correct about some models using galvanized bolts. I even saw one this week which had been upgraded to stainless bolts, but the nuts were still a more corrosion-prone material (oops!).

:: aluminum chainplates and, I've heard, galvanized keel
:: bolts. Neither is acceptable.
