When two powered vessels approach each other in a head-on situation, both operators should:
- Alter their course to starboard (right).
- Pass each other port side (left side) to port side.
- Maintain a safe speed and keep a vigilant lookout.
- Make their turns early and substantial enough to be clearly visible to the other vessel.
- If necessary, communicate intentions with sound signals (one short blast to indicate turning to starboard).
This maneuver helps reduce the risk of collision by creating a predictable and safe passing arrangement, ensuring both vessels pass each other safely on their left sides. Both operators are responsible for avoiding a collision by taking these actions promptly and clearly. If one vessel signals with a horn blast, the other should respond with the same signal to confirm understanding.
