[C320-list] Mystry water under H-tank (was "no subject")

[Jon Vez]

Warren,

A couple of additional possibilities--the one that nobody wants to even
think about would be the hull\deck joint and other would be the 'thru hull'
where the holding tank vent is. I don't know how your boat's vent comes out
of the hull, but I have a vent on the starboard side. If you have same and
it is not sealed, water could be getting in this way. Just a couple of
additional thoughts...

Regards,

Our season is coming to a close soon, so I don't know if I'll get to the
bottom of this by then. 

I bought a Beckson pump at ACE Hdwr (www.beckson.com/hmpumps.html) and it
very handily removes most of the water. Moves a good volume, too. Also, can
be used for diesel.

For those following this issue, you may find this interesting. I didn't used
to retain water under the holding tank. Damp, a little water, but not 2 gal.
Until, that is, I replaced the holding tank and in the process plugged a
whole that, apparently, allowed the water to drain from under the holding
tank to the space between the liner and hull. Now, after a sail in 15-20kts,
it collects and doesn't drain. I can't find water collecting in any quantity
elsewhere. The mystery to me is if the source is the space between the liner
and hull, how is it getting into the stbd settee area?  

As for having a hole under the holding tank to allow the water to drain back
under the liner, seems to me the whole space under the stbd settee needs to
act as a sump in case a battery leaks. I surely don't want battery acid
getting into the hull/liner space.

BTW, I use the Gore-Tex packing and no way do I get gallons from that. I
also sail with the tranny in reverse (no shaft rotation.)

Any and all ideas appreciated.

Wow. So it seems I'm not alone. I, too, have been collecting clear water
under the holding tank. It's a tough area to get to.

I will continue to try to figure out the source and will also pass along
anything I find.

We've encounter the same problem, with seemingly clear water under the
holding tank.  It tends to show up after a strong sail with heavy heel.
We've tried to figure it out by eliminating other sources but we are still
clue less.  Please keep us posted if you find the source.
