On board the coastal minelayer Plover (1937) under way during a minelaying exercise in Stokes Bay, The Solent. The photographer is on the starboard side of the quarterdeck looking aft showing two exercise ground mines with a sand filled dummy moored mine with sinker and flare float between them sitting on the end of the rails ready for dropping. The main winch is in the right foreground and some men are near the stern.
