While providing a complete navigation system and alert, reflecting the position of the vessel to safe navigation with audible and visual warning if the vessel escaped its progress or when it passes from shallow water or imminent collision with other objects whose position is defined.A second feature of the GPS devices that make them very useful, that can store the coordinates of various locations (Most devices have a memory for storing at least 500 points). This can be stored in a memory location and GPS to steer the boat there.
