What is the main advantage of knowing tidal currents for a navigator?

Understanding tidal currents provides significant advantages for navigators, primarily in terms of optimizing sailing routes and timings. Tidal currents can greatly influence a vessel's speed and direction; being aware of these currents allows navigators to plan their voyages more efficiently. By harnessing the power of favorable tidal currents, vessels can minimize travel time and fuel consumption, improving overall operational effectiveness.

Navigators can also avoid unfavorable currents that could lead to delays or increased fuel use. Knowing when and where these currents flow helps in making informed decisions about departure times and routes that take advantage of the natural movement of water. This knowledge is critical for effective navigation, particularly in coastal areas where tidal effects are pronounced. It allows navigators to predict the vessel's performance in relation to the ebb and flow of the tide, ultimately leading to safer and more efficient sailing.
