HMS C33 was a C-class submarine built by HM Dockyard, Chatham for the Royal Navy. She was laid down on 29 March 1909 and was commissioned on 13 August 1910.

Service history[edit]

C33 was involved in the U-Boat trap tactic. The tactic was to use a decoy trawler to tow a submarine. When a U-boat was sighted, the tow line and communication line was slipped and the submarine would attack the U-boat. The tactic was partly successful, but it was abandoned after the loss of two C class submarines. In both cases, all the crew were lost.

C33 was one of the two C class submarines sunk because of the tactic. She was mined off Great Yarmouth while operating with the armed trawler Malta on 4 August 1915.
