A veteran sailor is someone who has a lot of experience in sailing and navigating the seas. They are often referred to as 'SALT' due to their long-term exposure to the salty ocean air. They are also known as 'TAR' because of their familiarity with the TAR used to waterproof ships. A SEADOG is a term for a veteran sailor who has been at sea for a long time, and an old SALT is a term for a veteran sailor who has been at sea for an even longer period of time.
