The pound we were now in was obviously very low. The reason we were stuck in the lock was that we were sitting on the bottom! If I’d thought it through earlier, I might have suggested the sensible thing to do was to refill the lock, reverse out and moor on the lock bollards. We could then contact Canal and River Trust (CRT) and wait securely there until the pound was refilled. Once we were out of the lock however, we would have very little chance of getting back in. We seemed able to make progress, though it was under 1 mph, so we pressed on. I thought we might be completely stuck under one bridge, but with a bit of bow thruster and patience we managed to get through.
