Leaking from starboard side

[g5665]

Hi all dear Yamaha owners

I’m disturbing you guys again!
During the renovation process of the interior in my Y25MKii I came across some leaking problems.

One was already mentioned here and was related to the starboard side wood pillar inside the cabin. I opted for not removing the pillar because, as suspected, was part of the structure of the boat being the connection between the shrouds and chainplate. (pic2)

However, I detected some more infiltrations in the boat connects to the shrouds.
I suspect that both shrouds, Upper shroud chainplate and Lower shroud chainplate are not well sealed.

Also found a leaking in the bow of the boat with water accumulated in the v-bert area (not much, but some) that comes down running down the wall on the starboard side thru the interior lining of the wall (it’s all wet the fabric in that area). (pic1)

I suspect that can be a sealing problem in the Head stay fitting also. These are all problems on the Starboard side of the boat.

Is there any way that the sealing can be improved without having to remove the all chainplate and shroud systems?

Or, can I remove, one by one each time, and proceed to a good sealing, and put it in place again before moving to the next one?

I’m new on this and where I live don’t have much places to do boat work neither have people who know how to do it. If I want professional work (which will be pricey) need to sail the boat to Hong Kong (I’m in Macau, 42 miles from Hong Kong) and leave it there.

Thank you for the ideas

The chainplate looks like a straight forward fix. I'd tie off the mast with a halyard, disconnect and remove the chainplate. Then I'd replace the wood bulkhead and reseal the thru-deck. As far as the headstay fitting..... you can remove and reseal that also... again use a halyard for mast support. What you may want to check is the stanchion bases for leaking also, not a particularly difficult fix... Also... the hull/deck joint may have leaking issues.... try squiriting water under the rub rail and look for seeping.... While removing and replacing the rubrail is a chore... you may be able to shoot some sealant in any obviouls places without doing that.

May i ask...

If i remove, one each time, the chainplate, and then, after that fixed and assembled back, remove the headstay, still need to secure the mast with a halyard?
It make sense and seems safer securing the mast all the times of course...the problem is that the marina where we have the boat don't have facilities at all and we dont have way to secure the mast unless use the existing stays.

If remove just one of the stays (since they are at least 6) will afect in anyway the stability of the mast...

I have had some rethinking on bedding lately. Here is a link from a knowledgeable source

Whatever you do don't use silicon.

Yes - you'll need to support the mast on each side and slacken off the shrouds evenly or the mast will bend to one side (which can be a bit of a worry!) For support, nip up the spinnaker halyard on one side and the main halyard or topping lift for the other side. Leave the forestay and backstay on. This will enable you to pop off the shrouds on both sides without leaving a wobbly stick...

I encountered the leaking in the front V berth during heavy rain . I found out the leaking was from the bolts of the railing . The link from harryjak gave very clear illustration for the reinstallation of the bolt to prevent leaking .
