I can't find the source of water leaks in two locations. In the past, never had any water accumulation.1. Under the galley sink. I've capped off the water line but still get standing water. The only place it could be coming from is the thru-hull. Closed the valve & still have an inch of water after a sail. Thru-hull looks dry.2. Bilge. Three possible sources: a. Compression post has a little rust at the base but I've put towel around the post and it is dry after sail. b. Overflow from ballast valve. I've tried to make sure I close/plug the valve but still have water in bilge after sail.c. Deck/hull seam at stern. The area behind the aft wall always appears dry but a couple of inches of water always in bilge after sail. At the dock this seam is only an inch or so above water. This seam is under water most of the time we're sailing and I've always assumed this is normal.Any suggestions or experience with leaks from H26/260 owners will be appreciated.
