What type of information does a navigation chart provide?

A navigation chart provides critical information about water depth and underwater hazards, which is essential for safe boating. These charts depict various features of the waterway, including the bathymetry, or depth contours, which help boaters determine safe passages and avoid areas that may be too shallow or contain dangerous obstacles like rocks, sandbars, or wrecks. Understanding this information is vital for navigation, as it minimizes the risk of running aground or encountering unexpected hazards while on the water, ensuring a safer experience for all on board. Thus, focusing on water depth and underwater hazards allows boaters to plan their routes effectively and maintain safety on the water.
