My chain plates come up through the ply deck , as of most chain plates they are a source of leaks .
one chain plate has rot around it which I knew of before buying the boat the others all showing signs of rot .
first job I did was to seal the plate with sika flex which seemed to work laying liberal amounts of sika around the plate, but I am finding the movement of the plate is breaking the seal while sailing
can the brain trust share their ideas on a better fix thanks .
First thing to do is re-seat the chain plates bolts preferably in epoxy to stop movement there.
Next cut some say 25 mm tufnol or alloy or hardwoood discs about 60mm round or oval if you like (Depending on chain plate size)
Cut the inside to fit the chain plates leaving a say 20mm gap around chain plate.
Place these over the chain plate (even screw it there to the deck)
You should then have a 25mm deep recess around the chain plate as it come through the deck.
Fill with a soft sealant that does not fully harden (not all silkaflex in the same)
The added thickness of the sealant allows more movement before cracking and leaking.
Problem solved!

Thanks Lydia I knew you would have the answer do you have the name of the sealant a number of it ?
