In December 2017 I had the opportunity to spend a few days on board the Royal Navy's HMS Enterprise on her trip from Limassol, Cyprus to Valetta, Malta. HMS Enterprise is a survey ship, her primary task is to map the sea floor using sonar and feed the data into civilian and military maps. In this detailed episode, we chat about the ship, its mission, the survey equipment, the technical aspects of the propulsion and systems, plus about life on board a ship and nautical issues in general.
