Question 929 Rules of the Road

The correct answer is D) Hold your course and speed. According to the International Regulations for Preventing Collisions at Sea (COLREGS), when you hear a fog signal of two prolonged blasts on your starboard quarter, it indicates that another vessel is making way ahead of you on your starboard side. In this situation, you should hold your course and speed, as the other vessel is required to take action to avoid a collision. Changing course or stopping could create a dangerous situation, as the other vessel may be expecting you to maintain your course. The other options are incorrect because they would not be the appropriate action to take in this scenario. Changing course to the right or left could put you on a collision course with the other vessel, while stopping your vessel could also create a hazardous situation.
