What should the give-way vessel do in a crossing scenario with a risk of collision?

Answer: A — Take evasive action immediately

In a crossing scenario where there is a risk of collision, the give-way vessel is required to take evasive action immediately to avoid a potential accident. This rule is rooted in the COLREGs (International Regulations for Preventing Collisions at Sea), which stipulate that the vessel that is stand-on must maintain its course and speed, while the give-way vessel must take appropriate and timely steps to avoid a collision. Taking immediate evasive action may include altering the vessel's course or speed accordingly, which can help ensure safe passage and maintain situational awareness. The intent is to prevent close-quarter situations and collisions, emphasizing the responsibility of the give-way vessel to act decisively when the circumstances indicate a risk of collision. Maintaining course and speed, or waiting for the other vessel to move, would potentially lead to a dangerous situation, as these actions do not address the immediate threat of collision. While decreasing speed can be a component of evasive action, simply slowing down without a change in course could still result in a collision if the other vessel does not alter its own path.
