Question 11

The Correct Answer is B **Explanation for B (Correct Option):** Option B is correct because it accurately reflects the responsibilities of the stand-on vessel under both the International Regulations for Preventing Collisions at Sea (COLREGS Rule 17) and the Inland Rules (which mirror the International rules regarding stand-on responsibilities). The stand-on vessel (in this case, the power-driven vessel that is designated as stand-on in a crossing situation, typically the vessel on the starboard side of the give-way vessel) is **required to maintain its course and speed** unless the give-way vessel fails to take appropriate action. This requirement ensures that the give-way vessel can accurately predict the stand-on vessel's movement when executing its maneuver. However, Rule 17(b) and (c) explicitly state that the stand-on vessel **may take action to avoid collision** once it becomes apparent that the give-way vessel is not taking appropriate action, and **shall** take action if collision cannot be avoided by the action of the give-way vessel alone (i.e., at the point of imminent peril). **Explanation for Other Options (Incorrect):** * **A) required to give-way in a crossing situation:** This is incorrect. As the "stand-on" vessel, it is the primary responsibility of the other vessel (the "give-way" vessel) to maneuver out of the way. * **C) required to sound the first passing signal in a meeting situation:** This is incorrect. In a meeting situation (head-on), neither vessel is strictly "stand-on" or "give-way" until a decision is made to pass port-to-port or starboard-to-starboard. Passing signals (one or two short blasts) are sounded by the vessel **taking action** to indicate its intention and initiate the maneuver, not necessarily by a designated stand-on vessel. * **D) free to maneuver in any crossing or meeting situation as it has the right of way:** This is incorrect. While it has the "right of way" (it is the stand-on vessel), it is specifically **not free to maneuver** initially. It is restricted by the requirement to maintain course and speed (Rule 17(a)(i)) to allow the give-way vessel to maneuver predictably. Full freedom to maneuver only occurs later when collision avoidance becomes necessary.
