What is one consequence of improper dead reckoning?

Improper dead reckoning can significantly increase the risk of becoming lost or straying off course. Dead reckoning involves estimating one's current position based on a previously determined position, accounting for factors such as speed, time, and direction. If any of these factors are inaccurately measured or if there are errors in calculation, the vessel's actual position can deviate considerably from its intended course. This deviation can lead to navigational errors, making it difficult to arrive at the specific destination and increasing the chance of encountering hazards or running aground.

While improved navigational accuracy, increased fuel efficiency, and faster travel times may be desirable outcomes of precise navigation, none of these can be achieved if dead reckoning is improperly executed. Instead, the primary consequence is the heightened risk associated with navigational errors, leading to unsafe situations.
