Navigational is a term used to describe the process of navigating, or finding one's way, through a particular area. The term can be broken down into three parts: SEA (3 letters), MARINE (6 letters), and NAUTICAL (8 letters). SEA refers to the ocean, MARINE to the activity of sailing on the ocean, and NAUTICAL to the knowledge and skills required for navigation. Together, these three terms form the basis of navigational activities.
