When Crossing Paths, What Is the Give-Way Vessel's Responsibility?

The answer

In a crossing situation, the give-way vessel is the boat required to yield. Its responsibility is to take early and substantial action to keep well clear of the other boat. In practice that means changing course, reducing speed, or stopping in enough time and by enough margin that its intentions are obvious, and then passing safely behind (astern of) the stand-on vessel. The give-way vessel should avoid crossing ahead of the other boat.

Under the Navigation Rules, when two power-driven vessels are crossing so as to risk collision, the vessel that has the other on its starboard (right) side is the give-way vessel. A helpful memory aid: if you see the other boat on your right, you give way — think of it like yielding to traffic on your right.

What the stand-on vessel does

The other boat, the stand-on vessel, is expected to maintain its course and speed so the give-way vessel can predict its path and maneuver around it. But "stand-on" does not mean "ignore everything." If it becomes clear the give-way vessel is not taking sufficient action, the stand-on vessel must then take its own action to avoid a collision. The stand-on vessel's steadiness is what makes the give-way vessel's job possible — two boats both maneuvering unpredictably is how collisions happen.

Give-way and stand-on across situations

The piece most law-firm blogs skip is how these roles shift with the encounter type:

• Crossing: The vessel with the other on its starboard side gives way; the other stands on.
• Meeting head-on: Neither is purely stand-on — both power-driven vessels alter course to starboard and pass port-to-port. Each shares the duty to avoid collision.
• Overtaking: The vessel coming up from behind is always the give-way vessel and must keep clear; the boat being overtaken is the stand-on vessel and holds its course.

Remember too that under the rules certain vessels generally have priority (for example, vessels not under command, restricted in ability to maneuver, or engaged in fishing), which can change who must give way regardless of the geometry.

The bigger picture

The whole point of give-way and stand-on roles is to make each boat's behavior predictable so operators can anticipate one another. The give-way vessel acts early and decisively — small, late course changes are dangerous because they are hard to read. When maneuvering, boaters also use sound signals to communicate intentions: one short blast to indicate an intended pass on one side, and the danger signal (five or more short, rapid blasts) when intentions are unclear or a collision risk exists. Knowing that the give-way vessel yields, keeps clear, and passes astern — while the stand-on vessel holds steady but stays ready to act — covers the core of right-of-way exam questions.
