[C38] Port forward chain plate

Wed Oct 19 00:42:04 EDT 2011

A little more information on the problem of water under the counter top in the head.  As I started digging into the problem I found that my port cabinets in the salon were soaked, the chain plates leaked a bit, but the big culprit was the vented stanchion, as it turns out water runs down from the stanchion base, down the bulkhead and to a molded fiberglass detail which leads directly to the head, under the counter top right where the water was collecting, as well as what I suspect is when water fills up under the counter top it then migrates down under the forward port settee cushion behind the slight opening hidden behind the quarter round trim pieces.  Then it pools and soaks into the bulkhead.  My bulkhead just under the lowest bolt to the fiberglass seat was very very wet.   it also turns out the leaks from the chain plate will also find their way to the head under the counter top. I found this out after removing the chain plate and spraying mold killer at the top and watched it run down and through the cabinets.  attached photo should easily show the leak routes.

Thanks Dave and Steve.  Its always good to know what your getting into before you take things apart.  I had a Catalina 27 in which I repalaced both bulkheads, and I can only imagine things are similar.  Dave I see you in/near San Francisco.  If you'd like company when your taking it apart I'd be happy to come out.  Contact me off list.  Kerry

Kerry,

When I finally get into the destruction/reconstruction there will be photos. IF I remember to take them. I often get into a project and forget all about documenting it.  
Steve's description is great, but the construction of my counter top seems to be constructed a little differently. The bottom of the counter is actually glassed into the hull and will require cutting to remove.

	Dave, 

	My head cabinetry is now apart and I replaced the counter top three years ago when I got the boat.   Here is what I know or at least how my boat is configured.   The counter top is screwed from below to the glassed cabinet.  You will need to first mark and loosen your forward shroud, then you can remove the brackets that hold the bulkhead to the counter top.  Remove sink and faucet and the screws underneath holding the counter top in place.  You might have to remove the drawer frame to get to one of the screws.    It should then slide out with some pulling and tugging.  Mine was so bad I went ahead and replaced it with a new one, I should have painted the bottom now that I think about it.  To get the bulkhead out the face of the cabinet has to come out then the shelves, Mine was screwed from the front and the sides aft the screws should be outboard of the chain plate in the salon and in the vee berth they are in the cabinet, you might have to remove the false back in the upper cabinet, I removed mine altogether some time ago to pick up the added space and to do some rewiring.   My bulkhead was in okay shape but I went ahead and expoxied the edges to keep any water in the future out as well as varnish on the bulkhead itself.  The holes in my bulkhead where the chain plate attaches were elongated so I filled with epoxy and redrilled,  The holes in the aluminum brackets that hold the bulkhead to the counter top were also elongated so I drilled them out to the next size up and then treated the back with zinc chromate, primer and then paint to keep them from corroding.  As the corrosion grew on the bracket it ate away at the bulkhead, so I filled the area with epoxy too, also redrilling those holes.   I made up a backing plate for under the countertop as there were only washers.   If you go this far you might as well remove the chain plate which is now only held in place with two bolts, After removing the chain plate I used my dremmel to open up the deck around the chain plate as I was told by the boatyard that you really need at least a 1/4" all the way around to get enough sealant inside to seal as the chain plate shifts under load.  I felt the washers were undersize on the deck so I upgraded to fender washers and am not sure that did any good as they compressed into the depressions the old washers made in the deck as I tightened them, but the added area of sealant underneath them cant hurt.  As Im thinking this through I think I will remove the counter top and paint the bottom side, because water back there is a problem might also be a good idea to drill some holes in the glassed cabinet to allow water to drain,  I did caulk around the edges of the counter top when I put the new one in, but looking at it tonight some of it has failed and that would explain the musty boat smell.  I am also while I have it torn apart going to move the faucet to the left side of the sink and change its rotation so it is point with hot water handle to starboard and cold to port rather than fore and aft, then where the faucet use to be Im going to put a piece of teak across so that there are two open storage compartments rather than just the one.   Hope this helps. 

	Steve

	Steve,
	This project has my intense interest. I recently discovered a problem with the same bulkhead as well as the counter in the head. There was a slight leak that channeled water down the back of the bulkhead and between the hull liner and the counter. The counter is glassed into the hull on the bottom only so the water gets trapped in the space between the hull and the counter. The result has been that the back 1/2 inch or so of both the bulkhead and the counter have rotted. I am struggling now with a plan to replace or repair both the bulkhead and the counter. 

	Dave

	        I am in the process of repairing the port forward chainplate bulkhead the one in the head,  short version: I noticed a bulge on deck inboard of the forward chainplate, looks like the bolts outboard also compressed the deck, so the entire chainplate swiveled on one bolt on the bulkhead, the one in the center as it was the only hole of the four holes in the bulkhead that did not elongate.  Im making a new bulkhead and will reassemble but was wondering if anyone else has seen this problem in their boats and what did you do?  I dont see anyway of getting the bulge out of the deck as the way the way the chain plate is fabricated there is no attachment to the deck where it bulged.  Thanks
