[C38] Chain Plates still leaking

[Phil Gay]

Steve,

 

I wonder if  it would be possible to weld a thicker deck plate at the right
spot on the chainplate so that the gap between the chainplate and the deck
plate could be eliminated.  One would have to remove the chainplate, but the
upper-mid chainplates are not too difficult to remove and replace.  Some of
the newer boat designs have this type of chainplate anchor and it would
enlarge the amount of chainplate to deck surface that the sealant is applied
to.  There has to be a better way.

I found water after today's rain on the starboard quarter berth in
approximately the same location Phil found it on the port side in the galley
cabinets.  After thinking about how he traced the water from one of his
lower chain plates through a maze of butted plywood im quessing I have the
same situation.  After investigating deck side I found thin seperation
cracks between the chain plate and the caulk.  My chain plates as I assume
others are not centered in the cutouts and make it near impossible to get
enough sealant in the gaps to make an effective seal considering the
movement between the chain plates and the deck.  Im sure something as simple
as applying silicone to the hardware topside would offer a temporary fix.
I came up with an idea I wanted to toss out for comment:

 

Assuming the problem is the tight clearances on one side or the other of the
chain plate to the deck plate I am thinking of fabricating some new deck
plates that are one inch tall and have a larger cutout for the chain plate
to pass through.  This should allow for enough sealant to be applied on all
sides of the chain plate as well as offer another inch of sealant depth.
Im fortunate to have a machine shop and a rubber company, so it would also
be feasible to mold a rubber boot to slide over the rigging and cover the
deck plate if needed.  But I think the deck plate alone should solve the
problem.  Your thoughts please, Thanks.
