Traveling by boat is a popular form of transportation, especially for those who enjoy the open water. Sailing is a common activity that involves navigating a boat using the wind and other natural forces. It requires skill and knowledge of the environment to be successful. The term 'SAIL' is used to describe the act of traveling by boat, and it is also used to refer to the large piece of fabric attached to the mast of a boat that catches the wind and propels the vessel forward.
