Rebedding needed?

[NewToTheRoad]

After my first sailing season with the new boat I notice some staining around the chainplate hardware on the deck.  Oddly, in the sunshine it looks more to be a pink color than anything else.  However due to it's proximity and inability to wash off I am thinking it must be rust staining perhaps from water getting underneath.  Maybe it's time to remove, clean, and re-bed with butyl.  I know that the PO had never done that.  Am I on the right track here?

Thanks!

It looks as though the bolts are sunken in to the deck and that water would pool there.

If you do rebed them, you might dig out the core around the bolts and replace with resin and filler and redrill.

Not sure how to get the deck level back up.

I did the rebed job on Eximius just a few months ago, painless.

1.  It looks as though the bolts are sunken in to the deck and that water would pool there.

1.  The bolts are countersunk.  If sealed properly, H2O shouldn't get in.

2.  Until you remove them, you won't know.  Mine were fine.

3.  You don't have to.  The cover plate is the barrier.  See Chainplates 101, link to pictures I took of my rebedding.

4.  Painless is right!    One at a time, easy.

Any specific questions, please ask.  You might also consider using FSR on the stains.

Since the boat is new to you, I'd want to know the condition of the deck core at the chain plate penetrations.  Remove the cover and chain plates and inspect the core.  If wet or rotted, you'll need to address this.  There is at least one good article on inspecting, remediating, and potting/sleeving/sealing the chain plate penetrations with epoxy, which a good investment in your deck core life and your piece of mind.

Would follow the advice on rebidding and inspecting the core.  There should be a lot of brown(rust)color below the deck.  I think the the brown color is coming from your rigging. Just a thought.

    Don't forget to inspect rigging, top to bottom. You may want to think about using large fender washers to spread the compression load.

To add to Phil's advice on the fender washers, be sure to not overtighten the chain plate bolts.  The shrouds and the chain plate anchors are doing most of the mechanical work.  The chain plate bolts more or less "position" the chain plate only so no need to overtighten and unnecessarily crush the decking and core.
