Coastal navigation is the practice of navigating ships and boats along coastlines, using landmarks, charts, and navigational aids. It involves understanding water depths, tides, and currents to ensure safe passage near shore. Mariners often rely on tools like buoys and lighthouses to guide their way. This type of navigation is essential for fishing, recreational boating, and commercial shipping. It helps sailors avoid hazards such as rocks and sandbars, while also allowing them to access ports and harbors efficiently. Coastal navigation combines traditional skills with modern technology, enhancing safety and accuracy on the water.
