Are you sailing during the day? Is it raining at all? I don't know about your boat, but mine is a somewhere between an elegant, beautiful elderly woman and a fat old bag. The POs maintained some things and not others. The last PO was nice enough but had NO BUSINESS being on the water in anything, let alone a sailboat. Just saying. So, one of the items not maintained is the toe rail. I have to pull them both up, reseal the deck joint and rebed the rail. As it is, the carpet is always damp and often outright wet. Maybe you have a nuisance leak like that.
