How does understanding tides assist in navigation?

Understanding tides plays a crucial role in navigation, particularly in coastal and shallow water areas where changes in water level can significantly affect the safe passage and maneuvering of a vessel. Tides influence when and where vessels can safely navigate, as they dictate the depth of water in channels, the approach to ports, and the management of navigational hazards.

When a navigator is aware of the tidal schedule, they can time their departure and arrival to coincide with optimal water levels. For instance, with the understanding of tides, a navigator can plan to enter a harbor during high tide when the water is deep enough to avoid grounding on submerged obstacles or shoals. Similarly, certain channels may be navigable only during specific tidal conditions.

Positioning is also enhanced by tidal knowledge. Vessels might take advantage of the tidal current to aid their speed or maneuverability, planning their routes to harness favorable tides, thus improving fuel efficiency and reducing travel time. Therefore, being informed about tidal patterns is essential for safe and efficient navigation.
