Leak at baby stay chainplate on 54
|
We have been enjoying a couple of rainy days here in Turkey. Sometimes really heavy rain, so an opportune moment to look for leaks. Apart from some stitch holes in the spray hood we only have one.
I noticed a small puddle under the floor in forward port cabin next to the depth sounder transducer. Fresh water and a small trickle from forward. Long and short of it is that it is coming from the inner inner forstay. Then running down behind the lining and out below the cupboard in the port forward cabin. Then draining aft. The problem is that the shower moulding hides it. What I would like to do is remove the chain plate and re-bed it. However without cutting an access hole it is not possible. I had the same leak a couple of years ago and bodged it by running a bead of sealant around the plate outside. Looks like I will do that again… Has anyone else been here? Can offer better solution?

Nick, I am not sure, but I think it may be able to be caulked on the deck. Here is a photo of an A55 staysail chainplate from inside the forward locker. The two smaller bolts are from the top fixture on deck shown in the 2nd photo. There are four of these bolts, with two inside the front locker and two on the other side of that bulkhead. I do not know how accessible the other two are, but this is what your challenge is and I would really like to know how this is going to work for you. Also, I wonder what the second small plate on the deck is for??

Hi Nick,
the deck passage of the baby stay also leaked on Mago del Sur. We reset the chaine plate and sealed it. If my memory is correct 2 screws fixed the plate to the deck. Both located aft of the chain. Now the connection consists on 5 screws (see first pic). I would have preferred to turn the angle of the chaine above deck by 90°, as the load angle would be more favourable, but this seemed to be too much effort and we left it as it was. In order to access the main bolts of the chaine below deck, we had to enlarge the existing inspection opening in the forward bathroom. Cover f the opening see pic 2. The fastening bolts of the chain were cleaned and new nuts including new washers were put on.
This was an opportunity to inspect the space between the bulkhead and the cell of the bath. We found a lot of corrosion caused by the leakage on the bolts, nuts and screws accessible through the inspection opening. Then we discovered that the bolts (no stainless steel!) of the handle bar in the bath were completely corroded. The bolts of the handle bar go through the bulkhead into the small cupboard at the top of the passage to the bathroom. When the handle bar was replaced, it turned out that one of these bolts ran through the middle of a three-core flat wire. (Note: this kind of cable is designed for in wall use. In my eyes it has no place on a boat), which supplies the lights on the front bulkhead and in the bathroom. The very hidden cable was warm and the insulation burnt. It's a miracle that there hasn't been a cable fire during the last years. I assume that the handle bar was an original setting. If you have a bar in the bow bathrooom please check whether there is a slight voltage on the bar.

Nick, I have the same problem and it has been staining the inside wall of the forward head down to the towel bar for quite some time. Outside caulking did not work for me, even though I took off the inside plate to inspect and seal.
I think I will have to take the entire thing apart and reseal, but I would be interested in a successful solution short of that. Thanks, Jamie Phantom, A54 #44 |

By the way, I forgot to mention that I do not have that second plate on the deck, nor do I have the larger plate you show on the inside. I have only the upper curved plate, which limits access.
It seems that perhaps Amel was trying to ensure good access in later A54s and changed the design. Jamie Phantom, A54 #44 |

I have scraped out the old sealant and recalled from the outside. You will see in the photos that there are no fasteners on the deck fitting. That there is no access from the forward head.

I have had the handle bar in the head off and it is fine. There is no electrical current leakage. either. I used white exterior grade silicon outside, in the hope that it remains flexible. I need to decide if I will cut an access panel in the head moulding. I think I will, and cover it with a polished stainless plate. Still mulling it over, maybe I will inspect the fitting when going up wind in a stiff breeze for movement. Also photo of the staysail stay that has cover plate without fastenings. The chainplate is clearly visible in the forpeak so I have no worries there. Nick SY Amelia AML54-019 Marmaris Turkey    On 1 Nov 2021, at 17:29, CW Bill Rouse <brouse@...> wrote:

I decided to cut an inspection hatch.

See photos Looks fine as is for now, but if the problem persists I will pull the chain plate and re-bed it properly. Thanks to everyone for the general info. Nick Amelia AML 54-019 Marmaris On 1 Nov 2021, at 17:29, CW Bill Rouse <brouse@...> wrote:
