In a crossing situation, the give-way vessel must do which of the following?

• A. Keep out of the way and take early action to avoid crossing ahead.
• B. Stand-on vessel must maintain course.
• C. Both vessels stop.
• D. None.

Answer: (A)

In a crossing situation, the vessel that has the other vessel on her starboard side must keep out of the way and take early, substantial action to avoid crossing ahead. This duty is the give-way obligation under Rule 15 of the COLREGs. Practically, you should alter course or slow down well before the potential point of intersection to ensure you do not pass in front of the other vessel. The stand-on vessel should continue on its present course and speed, and only take action if the give-way vessel fails to act or if collision is imminent.
