The Inland Waterways Association runs this challenge to promote underused navigable waterways. To complete the challenge you take a photo of your boat at 20 of the destinations round the country: https://waterways.org.uk/waterways/using-the-waterways/silver-propeller-challenge
This year the Pocklington Canal has been affected by drought but hopefully will reopen soon and more boaters taking part in the Silver Propeller Challenge will be visiting the canal.
