In a crossing situation, what is the role of the give-way vessel?

Answer: B — Alters course to maneuver astern the other vessel

In a crossing situation defined under the COLREGs, the give-way vessel has a critical responsibility to take early and substantial action to avoid a collision. This means the give-way vessel should alter its course or speed appropriately to allow the stand-on vessel to pass without danger. Altering course to maneuver astern of the other vessel is a clear demonstration of giving way, as it involves taking proactive measures to ensure safe passage and maintain adequate separation. The intent is to avoid impeding the safe navigation of the stand-on vessel, which has the right of way. This action not only complies with maritime regulations but also promotes safety at sea by actively avoiding potential collisions. Maintaining course, increasing speed, or signaling to give way do not fulfill the obligations of the give-way vessel effectively. These actions could lead to confusion or increased risk of collision, as the primary duty of the give-way vessel is to maneuver in a way that prioritizes safety and ensures that the stand-on vessel can continue its course unhindered.
