The term 'Salts at Sea' is a reference to sailors, or 'TARS', who were often away from home for long periods of time. The term is derived from the fact that sailors would often have to rely on salt to preserve their food while at sea. The four-letter word 'TARS' is an acronym for 'Totally Awesome and Ready for Sea'. This phrase was used to describe the brave and hardworking sailors who served in the navy.
