You are seeing another vessel approaching, and its compass bearing does not significantly change. This would indicate that __________.

When observing another vessel approaching with a compass bearing that does not significantly change, this typically indicates that the two vessels are on a potential collision course. In maritime navigation, if the bearing of another vessel remains nearly constant, it suggests that the other vessel is either maintaining its course or speed in relation to your own. This scenario highlights the risk of collision, as both vessels might be heading towards the same point without altering their paths.

The concept of the “stand-on vessel” applies when one vessel is required to maintain its course and speed while the other vessel, known as the “give-way vessel,” must take action to avoid a collision. When the other vessel's bearing does not change significantly, it is crucial to recognize the risk of collision rather than assuming you are the stand-on vessel.

Understanding this situation helps operators make timely decisions to prevent collisions by either altering their course or speed to ensure clear navigation between vessels.
