A marine chart is a specialized map designed for maritime navigation. It provides essential information about water depths, underwater hazards, and navigational aids such as buoys and lighthouses. These charts help sailors and boaters safely navigate through oceans, seas, and other bodies of water. Marine charts can be either paper-based or electronic, with the latter often integrated into navigation systems. They are crucial for ensuring safe passage, as they indicate important features like coastlines, shipping lanes, and ports. Accurate marine charts are vital for both recreational and commercial maritime activities.
