Course Outline

Charts contain important information such as water depths and the locations of channels, overhead obstacles, bridges, and underwater cables. This is especially helpful when boating in bays or in large lakes. Charts also can be used to locate places, such as protected bays, coves, and docks, where you can take shelter in foul weather.
