Which vessel type listed has the highest priority for right of way?

The vessel type that has the highest priority for right of way is a vessel not under command. This designation refers to vessels that, due to exceptional circumstances, are unable to maneuver as required by the navigation rules. As a result, they must be given the utmost consideration from other vessels. The rationale is that these vessels are in a situation that fundamentally limits their ability to take actions to avoid collision or navigate safely, making it imperative for other vessels to afford them the right of way.

In contrast, while power-driven vessels, fishing vessels, and sailing vessels have their own rights under specific circumstances, they do not supersede the right of way given to those that are not under command. Prioritizing a vessel not under command ensures the safety of operations on the water and helps to mitigate the risks associated with possible collisions or navigational hazards.
