What are often called "traditional" working narrowboats were the product of the main canal system – but the craft that plied the 46 miles between Chesterfield, Retford, and the River Trent were very different. Isolated on the fringes of the inland waterways network there were no outside canal influences to change the design of craft that were adequate for the job they had to do. The cabins were below-decks, and the boatmen always had a home ashore. Short journeys, usually with a crew of two, did not generate colourful decorations of roses-and-castles, nor did engines oust the towing horse, not even as late as the 1950s. None of the original "cuckoo" boats have survived, although the last one was extensively measured and recorded in 1976, prior to it being broken up. This has enabled the Canal Trust to create a new boat, named the "Dawn Rose", which was constructed at Shireoaks Marina using traditional methods. Wood was bought in 2007, and construction started in 2011, with the boat being completed and launched in April 2015.
