Re: Ericson 27 Newbie Needs lots of advice.
There is another forum called Ericson Yacht Owners where you can probably get better model specific advice (if not find pre-existing threads on subjects like replacing the chain plates). Unless the chainplates are epoxied into the hull $1000 seems like a lot of money to replace them. On a boat of that era they would typically be bolted to the bulkheads.
boats that I sail on regularly: Pearson 28-2, Rondar 505, Yankee 30, Blanchard Junior
