I've had a problem this year with a small amount of water collecting in the central storage cubby (aft deck, below the floor, just outside the cabin door). The water is probably a maximum of 10mm deep and gathers only in the centre, low point, of the cubby. When I vacuum it out it's probably 0.5l max. It's a filthy brown colour. It doesn't get any deeper.
The water seems to come from the cut out where the water pipe from the shower drain passes through to the pump, but given the lack of use that pipe gets (the boat is hardly used and is not live aboard) and the colour of the water, I don't think it's from there.
Following a post on the Viking Owner's forum I got this advice:
"First of all, if it is a sloping floor it is likely to be the hull itself. Don't go anywhere near it with a drill unless you want to replace a small leak with a huge one. The fact that the water is very dirty suggest that it may have traveled quite some way, picking up dirt as it went. The actual leak is probably due to a leaky window, hull fitting or small cracks in the gunwale.This could be some way from cubby hole."
The reply dissuades me from my suggestion to drill a small hole in the bottom of the cubby to check for water under the floor!
This is all exceeds my competence level. Can anyone please suggest someone who would travel to Milton Keynes to advise what to do and/or repair.
Many thanks.
