The term 'Castaways' Escape Vehicles' refers to the RAFTS used by people who have been stranded on an island or other remote location. RAFTS are typically constructed from materials found in the environment, such as logs, bamboo, and other vegetation. They are usually propelled by paddles or sails, and can be used to travel long distances. RAFTS are a common form of transportation for castaways, as they provide a way to escape their isolated location and reach safety.
