Funnily enough I was cycling through Wigan his afternoon and there was a cruiser in lock 1 with men on the headgates. I asked the one on the towpath side if all four paddles were up and he nodded the affirmative. I then had a pleasant chat to the helmswoman who told me they had just bought the boat and were taking it up to Scarisbrick Marina. The guys on the gates were straining a bit on the gates so I asked the one on the offside if the ground paddle was up, there being no indicator on it. The paddle wasn't up, he lifted it and the gates opened in about another minute.
