H315 Chain Locker Drain

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I was doing some spring cleaning on my H315 today (and yes the springs were fine thanks) and I decided to open the inspection port in the forward bulkhead just forward of the fresh water tank.
When I looked inside the low point of that space had an impressive dried lake of wonderfully formed salt crystals.

(See picture)

There was pretty much no water no doubt it all having evaporated in the heat we have been having recently and because I haven't been to sea for several weeks.

But it got me wondering how on earth sea water was able to get into that space. I haven't hit anything so the hull is still intact.

The only through hull opening is for the chain locker drain which on my 315 exits on the starboard side about 200mm above the water line. Clearly at 200 mm in any kind of a sea the drain outlet is going to be under water from time to time - especially on port tack.

Here you can see the drain has two hose clamps.

Unfortunately the camera could not handle the poor lighting so the bright sunlight pouring through the fitting has masked any detail of the fitting.

I think the brown part to the left of the skin fitting may be sealant of some kind.

So my question is how to access these components to make sure the hose clamps are tight and that the skin fitting is installed correctly?

	This subject is mentioned in a few other posts. In my boat (and a number of other boats) the amount of water has been up to 15-20 liters. (By chance I discovered the problem after some years). I now remove 2-5 liters of water every year. The water ingress are from the points of assembly of the hull and the deck, which on some boats are not completely watertight. Some owners have tried to reinforce the assembly with Sikaflex, but it is rather difficult to get access to do the job. Since the water ingress is high on the hull, the amount of water is proportional to how often the bow is dipping into the water.
