To avoid a collision, what should be ensured regarding the passed distance from another vessel?

The correct choice emphasizes the importance of ensuring that the distance kept from another vessel provides a safe passage. This principle is deeply rooted in the COLREGs, which are designed to promote safe navigation and prevent collisions at sea. Safe passage means maintaining a sufficient distance that considers factors such as the size, speed, and course of both vessels, as well as environmental conditions like weather and sea state. By adhering to this guideline, mariners can reduce the risk of dangerous encounters and ensure that they have adequate time and space to react to any unforeseen circumstances.

Keeping a safe distance is vital for situational awareness and allows for potential maneuvers to be executed safely without the risk of collision. This is particularly crucial in situations involving larger vessels, limited visibility, or congested waterways where the margin for error is minimized.

Other options lack the necessary focus on safety and navigation principles. Approaching another vessel as close as possible for maneuvering efficiency disregards the potential risks involved. Similarly, stating that it does not matter if vessels are close undermines the fundamental need for maritime safety. The notion that distance should be based on crew assumptions can lead to subjective interpretations, which might not adequately account for the mechanical realities of maritime navigation or varying conditions. Therefore, emphasizing safe
