A bit concerned because the battery was down to 10.5 overnight, for no reason we can think of. If it happens again, we'll need to test by selectively turning off equipment overnight – assuming the new batteries have not failed.
Down the Ashton flight, mostly in the rain. Significant rubbish round the prop at one point – would have stalled the engine if I'd tried to drive. Half an hour to cut free something that at first looked like a tent, but probably wasn't.
6 miles, 18 locks, 1 swing bridge, 10 hours engine.
