Using tide tables provides essential timing for navigation because they give mariners critical information about the heights and timings of high and low tides in specific locations. Understanding tide patterns is crucial for safe navigation, especially in shallow waters where variations in tide can significantly affect water depth. This knowledge helps mariners plan passages effectively, ensuring they can navigate safely and avoid grounding or encountering hazards that may be obscured at low tide. Proper timing allows vessels to safely enter and exit harbors, cross bars, or traverse channels, particularly those that are influenced by tidal movements.
