Question 177 Rules of the Road

The correct answer is B) stand-on vessel. According to the International Regulations for Preventing Collisions at Sea (COLREGS), when two power-driven vessels are meeting in a crossing situation, the vessel that has the other on its starboard side is the stand-on vessel and must maintain its course and speed, while the vessel that has the other on its port side is the give-way vessel and must take early and substantial action to avoid collision. In the scenario described, vessel "I" has vessel "II" on its starboard side, so vessel "I" is the stand-on vessel and must maintain its course and speed, while vessel "II" is the give-way vessel and must take action to avoid collision.
