Hello there. I am new to this forum since I just got my boat in November. Had it put up on block for winter storage in January. Visited it 2 days ago to check on it and found water seeping out under my galley cabinets. Water systems are all off and winterized.

Doesn't look like I can remove the cabinets without destroying them, but was able to pull up the bottom board under the sink which allowed me to dry up the water (there was at about a half gallon.) It rained today, so I went back to check and there was more water. The wet areas are behind the two steps leading down to the galley and under the cabinets.
The water had also seeped under the parqueted floor boards which appear to be relatively new. Hopefully they will dry out without too much damage.

Is this rain water intrusion? Were would it be coming from? Bilge is dry. I've heard that water can get under the deck ??? If so, how does that happen? Bridge is covered with full enclosure.
Any ideas or suggestions would be greatly appreciated.
