As the give-way vessel in a crossing, which action should you NOT do?

• A. Veer to starboard to pass astern
• B. Cross ahead of the stand-on vessel
• C. Slow down and maintain course
• D. Stop and reverse engines

Answer: (B)

When two vessels cross, the one on the other’s starboard side is the stand-on vessel and should keep its course and speed. The give-way vessel must take early and substantial action to keep well clear. Crossing ahead of the stand-on vessel would put you directly in its path and violate its right of way, greatly increasing the risk of collision. So that action is not appropriate. Instead, you should take action to pass behind the stand-on vessel, such as veering to starboard to pass astern, or slow down to reduce risk while staying clear. In an emergency, stopping and reversing engines is an acceptable last-resort measure to avoid a collision. The core idea is to avoid crossing in front of the stand-on vessel.
