Whats the best way to go about this if there is no little plate around the chainplates? All 3 of mine are in lined up with the mast and all go through a big hole cut in the deck. Its a crappy way to do it, but thats how it was done long before i got the boat. Ive got to figure out a way to reseal them one ive got the bulkhead replaced. You can see how they enter the deck in the picture. The hole is all goobered up with 5200.
