History

The Mayflower is believed to be the oldest working tug in the world and marked her 160th birthday in 2021. 1861 Built on a slip adjacent to Pools Wharf in Bristol harbour (https://maps.app.goo.gl/7HgmNmGFvPGBW3Ft5) for Timothy Hadley, a towage contractor to Gloucester & Berkeley Canal Co. Initially she largely towed trains of small vessels such as trows and ketches between Sharpness and Gloucester. 1874 Sharpness New Docks & Gloucester & Birmingham Nav. Co. usually towing larger steamers one at a time. 1890s Modified with higher bulwarks to make her suitable for use on the river Severn, eventually working every part of the river from Worcester to Chepstow. 1948 British Waterways Board. Occupied as a mudding barge towing mud hopper barges filled by the dredging of the sharpness canal to the discharge point. She returned to ship-towing in the winter of 1963-64 when the canal froze and the diesel tugs had difficulty working in the cold. 1964 Withdrawn from service and sold for scrap in 1967. 1967 Consortium led by Anthony H Barrett Great Wyrley purchased Mayflower to conserve her. She was scuttled in Gloucester dock by vandals in the late 70s and was in poor condition when re-floated. 1981 Acquired for preservation, by the Bristol Museum of Technology. Restored 1982-7, first re-steamed Sept 1987. She is now on display at the M-Shed, part of Bristol Museums, and available for trips around Bristol Harbour: https://www.bristolmuseums.org.uk/m-shed/whats-on/mayflower-rides/
