Wellcraft 238 coastal 1996

[Dash-away]

Good morning fellow boaties
I have an issue with my 228 that has me worried and I am hoping somebody on here has some advice for me.
I just came back from a trip of approx 180ks in pretty crappy conditions.
Blowing approx 15kts with swells around 2-3 meters. The swells were approx 12 seconds so it wasn't that bad travelling through.
When unpacking the boat I notice water on the floor inside the cabin coming up through bung in the floor.
I have noticed water in there before and vaccummed it out.
I have no idea where this water is coming from or if it is ment to drain out the back.
The anchor well is dry so not coming in through there.
The bottom of the hull has no signs of cracks or holes and no water seeping out when water is in that compartment.
The compartment seems to be foam filled.
There is a little gallery in the Port side of cabin but not used and no water has been ever put in the sink bowl while I have owned it.( approx 3 months ).
I am trying to avoid cutting up the floor to investigate if possible. Thanks in advance.

I'm not sure but if it's a typical Coastal it's got 2 separate bilges and that bulk head there at the steps should be where it's divided. try getting a small mirror down in there and look around, see if there's a hole that drains it to the rear bilge or if there's a forward bilge pump. Also is there a porto potty on the starboard side? another good place to look to see if you can get a look under it. In seas like you described I would bet there was water laaing on the bow around the windless, that might have been letting the water in also

Good morning Cptbill and thank you for your reply.
The boat does have 2 bilge pumps but they are both at the back. There isn't a potty in the cabin or any other water sources. My first thought was the water coming in through the anchor well, so I sikiflexed all the joins and after the rough ride the anchor well was completely dry.
I did seal the bug with silicon and put compressed air through the bung with soapy water to find the leak. Hull and everywhere on exterior was dry. Next I put the garden hose down the bung and turned on. The water ran out of the rear main bung so it must get back there somehow. I will try find a drainage plan for the hull and see if it sheds some light on the problem

OK, next I would pull the cushions up and if there is a storage bin under there see if there's water in it, next start looking at places like windshield seals, hatches, potholes and where the hard top frame work bolts down. Looks there mite have been some water on that step going into the cabin so if you have drains by the cabin door check to see if there open

If you look at your close up on the drain hole, it appears there is a water mark coming down to the right of it from the floor above, My .02. I would investigate that.
