A starboard quarter view of the motor tug Knighton (1968) berthed alongside the Arethusa Pier in Upnor Reach, River Medway. She is dressed overall. An army style marquee is on the pier with people gathered outside it. A large crane on Patman's Wharf is in the left background and the Arethusa Training School is in the right background. The original negative enclosure had the letters HGMQM on it but the significance of these letters is unknown. Negatives numbers N86796CT and N86797CT were taken on the same occasion.
