We had another shopping trip before trying to set off along the canal. Yesterday as we approached Carnforth a woman on a boat going the other way gave me a warning. She said she’d had two jumpers wrapped around her propellor, “so – watch out!” This canal is so shallow that setting off from the bank usually feels sluggish, but today was so much worse than usual. By the time I was sure we had a problem, we were already in the middle of a large number of moored boats. I managed to limp across to a vacant space to check the weed hatch. Wrapped around the propellor were – two jumpers!
