What could be a consequence of failing to account for current while navigating?

When navigating, it is crucial to account for currents, as they have a significant impact on a vessel’s course and stability. Failing to consider the current can lead to the vessel drifting off its intended course. This drift can create unexpected situations, especially in congested or hazardous waters where precise navigation is vital for safety.

Moreover, if a vessel is not on its planned track, it can encounter dangers such as underwater obstacles, other vessels, or adverse environmental conditions that it might have otherwise avoided. Therefore, not accounting for the current could also indirectly affect the vessel's stability due to its altered position and unexpected encounters.

In contrast to this, the other choices either suggest extreme implications not typically applicable in such scenarios, or they incorrectly state that currents have no navigational impact. Options that dismiss the effects of currents fail to reflect maritime navigation realities where proper course adjustment is essential for maintaining safety and efficiency.
