Under the Navigation Rules, what does "stand-on vessel" mean?

The term "stand-on vessel" refers to the vessel that has the right of way in a crossing situation as defined under the Navigation Rules. This vessel is required to maintain its course and speed, meaning it should not change its path to let another vessel pass unless it becomes clear that a collision risk exists. The emphasis on maintaining course and speed serves to ensure predictable behavior in navigation, which is crucial for safety at sea.

The role of the stand-on vessel is balanced by that of the "give-way vessel," which must take the necessary steps to avoid a collision. Understanding the dynamics between these two types of vessels is essential for safe navigation among various marine traffic situations.
