Oceanis 45 electronics compartment & bilge water

[DRosen]

2013. Under starboard aft cabin is main electronics compartment. Heeling on Port tack, about 1 gallon of bilge water works it's way around the water tank aft of the electronics and spills into (under) electronics compartment, splashing around on battery charger, wiring harness and all else. Major problem! Has anybody experienced this? I drilled holes so most will drain, but not all. Any suggestions?

Do you mean the water accumulates somewhere and comes splashing out on port tack? There should be no water back there. I think you need to find the source. Perhaps the aft AC condensate pump is not working, or maybe the water tank fittings are leaking.

I agree there should not be water back there. I have observed some of the process. I believe the gallon and a half I have to remove collects throughout the flat bottom hull bilge area, the quart or so spilled from the bilge pump well and travels through the bilge And maybe the strength grid while sailing on port tack.
I have watched it flowing out from the centerline along the aft water tank, flowing forward to the small rib, forward of the water tank and at heel, sloshes around the upper end of that rib into the electronics compartment.
I have checked that the water tank is not leaking. I have replaced the rear A/C condensate pump. There is no evidence of water in that rear bilge area aft of the engine, leading me to believe the water is moving from forward areas.

I have drilled two drain holes to that electronics compartment, allowing draining forward into the pan under the aft cabin floorboard. Still not good, but better.
