I had a leak into the cabin on my 640 a couple of years ago. It took ages to find and turned out to be a couple of cleats that you tie the fenders on to, difficult to find the leak as the water was running down the boat and dripping no where near the leak.The water was ending up under the cabin floor. They get caught on quay headings and had worked slightly loose breaking the seal under them. Pulpit rails get knocked as well. There was a surprisingly large amount of water getting in through them.
So during a period of fine weather (if you can remember what that is ) I resealed all the deck fittings and have been bone dry ever since.
Thanks for all you suggestions
Same here, rain all weekend again, forecast is looking better for next weekend so I am going to try all the suggested places to reseal, including cleats, pulpits, all deck fittings etc, (if it stays dry)
Fingers crossed that will sort it,
It was abit of a dry period last weekend so I decided to see if there was water in the battery and petrol storage compartment and sure enough there was. I have come to the conclusion that the 2 tarpaulins I purchased from B & Q are not as waterproof as they are made out to be. It really rains a lot in the west of Ireland. I drained out all the water from the compartments and removed a bung from the floor only to discover that the foam underneath was damp and spongy. There is a small pinhole from both compartments into the superstructure that is leaking in water.
Will it be necessary for me to grind out part of the compartments floor so I can dry out the foam underneath or is there an alternative solution. I have no problem using 4.5 inch angle grinder.
