Which scenario would prompt the stand-on vessel to take action?

• A. The give-way vessel is not acting
• B. The give-way vessel is acting
• C. Both vessels stationary
• D. Weather conditions change

Answer: (A)

Under COLREGS, the stand-on vessel should hold its course and speed unless the other vessel (the give-way vessel) is not taking proper action to avoid a collision. If the give-way vessel is not acting, a risk of collision develops, so the stand-on must take action to prevent it by altering course, adjusting speed, or stopping as needed. If the give-way vessel is already maneuvering to avoid, the stand-on should maintain position and monitor rather than act, unless the situation deteriorates. When both vessels are stationary, there’s typically no collision risk requiring action. Changes in weather can affect planning, but they don’t by themselves force the stand-on to move unless the risk of collision with the other vessel changes.
