Chainplates out to measure for new ones. Oh boy, the cracking was worse than I thought at deck level. Readers digest version, is if you have a soft spot in your deck next to your chainplates, there is a REAL good chance that there is a cracked chainplate. Mine was 50% across the chainplate, all of the way thru the stainless. If I went sailing today, the mast would be toast. (20kts today) Going to let it dry out tonight, then play with epoxy and glass tomorrow. Will post photos later.
