On board the Royal Navy Ton class coastal minesweeper Glasserton (1953) looking to port and forward from the port side of the forecastle deck abaft the funnel while she is refuelling from the Royal Fleet Auxiliary tanker Grey Rover (1969) under way off Gibraltar in early 1980 during exercise Test Gate. The port derrick post of the Glasserton is on the right and two men wearing wet weather gear, hard hats and life jackets are by the port guard rail. Only the bow of the Grey Rover (1969) is in the picture.
