How can "current" affect a vessel's navigation?

The influence of "current" on a vessel's navigation is significant because it can alter both the speed and direction of the vessel. When navigating, a vessel experiences water movement, or current, which can either aid or hinder its progress. For example, if a vessel is moving with a current, it may travel faster than its engine can propel it, thereby increasing its speed. Conversely, if the current is against the vessel, it can slow down its progress, requiring the crew to adjust their navigation plans accordingly to maintain their intended course and arrive at their destination on time.

Understanding how current interacts with the vessel is crucial for accurate navigation, as it can lead to unintended deviations from the planned route. This requires the crew to make real-time adjustments not only in terms of speed but also in heading to compensate for the drift caused by the current. Hence, awareness of current conditions is essential for safe and effective navigation, encompassing factors such as tide changes and weather conditions.
