Chainplate shows lots of caulk around it - Normal?

Post by dlandersson »

I'm looking a a few Macgregor 26X's.

On one, the dealer says that the "chainplate shows lots of caulk around it, which is common on the MacGregor as that is a common spot for it to leak".

Any thoughts about this? I'm a bit jumpy about long-term water damage to the hull.

TIA. :)

All of the S boats I looked at were like that, including the one I bought...don't know about the X boats though. I would assume that it is liable to be a leak point because it is a high load point on a penetration through the deck, so more likely to flex/move.

The chainplates on my 26M started leaking when it was about 5 years old. I had them rebedded professionally. Now there are no more leaks. And I got the problem fixed early, before it really made a mess.

Go inside the boat and see if there is any visible sign of water having entered. On my 26M, the water stains were visible on the carpeted liner.

Also, slathering extra sealant around the edges of the chainplates may provide a temporary fix, but is not the right way to do it. Eventually, they will have to be removed and rebedded properly.

Anytime you have chain plates going thru the deck you will need to seal them often. The force of the deck/hull flexing along with the standing rigging will open up deck fittings even if they were bondeded with 3M 5200 7 day cure.
Clean off all chalking and soft wire brush with acetone than put on new marine silicone.
Do every year if useing boat often and like to get the rail down.

On the 26X the chainplates go through the deck and are bolted to the hull. The place where they pass through the deck is a potential source of leakage into the bilge. Because of the strain and stress of shrouds on plate, the plates want to move slightly relative to the deck. It's difficult to maintain a water tight seal there. When we bought our boat, the dealer recommended checking this place annually, and to use silicon seal rather than 5200 or 4200 sealant. The silicon is more flexible, and can be easily scraped off and reapplied. Someone who followed this practise might have just piled new caulk on top of old. This is easily corrected by scraping the old caulk off and resealing.

There is no area with (lots of caulk around) any part of my boat. There is caulking around many places tho! to me Lots of caulking around one area is a sign of shoddy maintenance. Usually I clean all the old caulking off, repair and then caulk a nice narrow bead of caulking where needed..

We had leaks from the bow and both side chain plates on "Imagine" I resealed them myself a couple of years ago and have had no leaks since.

Here is the link to how I did it.

This is a sealing method for the chainplates without reriveting them:

It worked fine until now 8) .

I would like my :macx: wood look as brilliant as Quebecs does, however this will never happen :(

Look at the common thread here which is "resealing" them. Get used to it you will have to do it too and more than once. :)

There is almost no wood in these boats so water damage risk isn't an issue ...

I found a "chainplate cover" on BWYachts.com in the parts lists that shows it fits all the boats.
P/N 4004-1V0 It's a $5.00 stainless plate with a slit in the middle that fits over your chainplates to help with sealing.
I'm thinking about investing in a couple of these, plus some silicone, to help out (and particularly to make the silicone invisible).
Any thoughts?

I cant pull up a picture of them so I can't say if they would be worth the money and effort. :?: :|
