Having served on this type of tug whilst working at Chatham Dockyard I was amazed and horrified to find this vessel being used in the Swale (the waterway dividing the Isle of Sheppey from the mainland) operating from Queenborough in the early 1990s by just one person !! He would start up her two engines, nip up onto deck, cast-off then sprint up into the bridge to take control. She was being used as a stand-by tug for vessels runing through Kingsferry Bridge (the only link between Sheppey and the main-land) to Ridham Dock. One could only hope that he didn't have a fall during his multitasking duties.
