At the bottom of the lock in the middle of Wigan, Clare shouted: “There’s a hedgehog in the lock!” I went to the front of the boat and indeed, swimming weakly, there was a hedgehog. I got the gangplank and tried to get it under its feet. At the time I thought it might have been scared of me, but I now think it was just too weak to walk. After a few failed attempts I realised I needed to get nearer. Clare was unable to get to the boat, so I went to the back again and drove gently forward. After another failed attempt I left the throttle on 10% forward – it doesn’t mention it in the manual, but this seems to be the ideal speed for hedgehog rescuing.
