 Large numbers of boats were built beside the Stainforth and Keadby Canal. Richard Dunston set up a boatyard at Thorne, on the north bank just below the lock, in 1858, after selling his previous boatyard at Torksey. He initially constructed clinker-built sailing barges, capable of carrying up to 80 tons. The boatyard was fairly self-contained, using timber which was grown locally and was sawn by hand at the yard. It included a ropewalk, which made ropes for many industries in the locality, as well as for rigging of the boats, and supplied sails, masts and chandlery to much of the Humber region. Gradually, carvel-built barges with their smoother hulls replaced clinker-built ones, and boat sizes became more standard, with Sheffield-sized keels and larger sloops. Shortly after Richard's grandson took over the yard in 1910, it was remodelled to build iron and steel ships, and only one wooden boat was built subsequently.
