Well, it wasn't the sterngland after all; I checked this morning and the basin under in was still bone dry. So unless it was the leaky water tank (and that was more of an ooze than a drip, and surely too far away for me to hear) then I don't know what it was. Maybe water condensing on the lid of the kettle and dripping back in. There's another mystery too - the disappearance of Jim's wash bag. He was sure he'd left it hidden in the hold, but when it wasn't there, thought he mist have taken it home. But it's not here either. It's clearly a slow news day, but I'll keep you posted if there are any developments. The good news is that the leaky fitting on the water tank seems to have been cured. I've polished the stove and much of th cabin brass. And that's about it. Sorry.
