Which vessels are denoted as "give-way vessels"?

The correct choice identifies "given-way vessels" as those that must take action to avoid collisions. Under the COLREGs, the "give-way" vessel has the obligation to take measures to prevent a collision, which often includes altering course or speed to allow the "stand-on" vessel to maintain its course and speed. This principle is crucial for ensuring safe navigation and preventing accidents at sea.

The definition of a "give-way" vessel is based on the navigating rules that establish obligations for vessels in various scenarios, such as when they are crossing, overtaking, or meeting. A "give-way" vessel does not necessarily have the right of way, which explains why the other choices do not accurately reflect the role of these vessels. For instance, vessels that have the right of way would be considered "stand-on" vessels, and those constrained by draft or engaged in fishing operations have specific rules that apply but do not define the general category of "give-way vessels."
