Hey everyone - we are seeing water in this small triangular receptacle just behind the trash can. We've done as much troubleshooting as we can including testing for leaks around the traveler, windows, and hatches. All looks good. What's so confusing is there is nothing above this area except a galley countertop. The pex tubes are intact and there are no other lines running nearby. We think it may be a leak somewhere above because the water appears to be fresh and we think (as best as we can tell) it happens after rain. But we're still in the testing phase.
The previous owner stored sponges here. Hmmmm......... Any thoughts would be greatly appreciated.

And the photo....

Have you already checked the seal of the fresh water tank?
We also had a water problem. After several years of searching, we have discovered that water leaks out of the inspection lid when the water tank was full.

Will give it a try.... thanks!

Which model boat? Do you have teak toe rails?
It may well be coming from the gunwales and running down inside.
-
No teak toerails but I'm guessing you may be right. It's a Vision 40. 2007. Is there any way to diagnose where the holes are???

The only way to find the leak is to keep looking until you find it, and assume nothing until you have found, fixed and proved that what you fixed is the leak that is causing all the trouble.
See my post from yesterday

As well as the fresh water tank also check the pump.

Check the outlet from your hot watertank.
It's common for the constant heating and cooling to cause this to leak.
We had it on our 34 and a friend had it on his bendyboat.
Trim the end of the plastic pipe and refit

Not sure if you have the split windows to the cabin? The side windows on later Bavaria's are in two pieces. (as ours) There is a joint between the perspex (plastic glass) which is about an inch wide and is filled with Sikaflex as part of the window bonding to the hull.
This joint has a 3 way bond (two edges and the cabin top). The perspex is held in position by a screw during production (making a hole)
When the screw is removed the joint is filled but the hole is not filled. There is no bond breaker between the cabin top and the Sikaflex at this point .
No mastic, sealant, or similar bonding agent can take being pulled in 3 directions when the boat and windows expand and contract as the temperature goes up and down. The dark windows also expand at a different rate to the white fibreglass deck sides.
This is a well documented known issue in the Facade and glazing industry where a non stick bond breaker is placed to allow the sealant to slide over the 3rd surface (ie the cabin top) but remain bonded to the window edges.
When the joint breaks, which it will at some point, water gets behind the sealant and through the hole Bavaria made and failed to fill in production.
We have had to take remedial action on Impavidus when she was just over a year old, and have seen at least 4 other boats with the same detail that fails.
Sika and Bavaria know about the issue. Sika's data sheet/technical bulletin makes a mention about it somewhere...
Water comes through the holeand runs down behind the inner detailing into the bilge at almost exactly this spot.
The splitting in the mastic/Sika is almost impossible to spot from the outside. But careful inspection sees the mastic de-bonded from the window edge.
This may be the cause of your hidden leak, it's worth a check...
Hope this helps.
