Question 47 ONC07 - OUPV-Near Coastal

The Correct Answer is D **Explanation for Option D (Correct Answer):** The required fog signal for a vessel being towed (and manned) is stipulated in Rule 35(e) of the International Regulations for Preventing Collisions at Sea (COLREGs), which applies to both International and Inland waters (where Inland rules typically mirror COLREGs for this signal). Rule 35(e) states that a vessel being towed or, if more than one is towed, the last vessel of the tow, if manned, shall at intervals of not more than 2 minutes, exhibit a signal of **one prolonged blast followed by three short blasts**. **Explanation for Incorrect Options:** * **A) One prolonged followed by two short blasts:** This is the required fog signal for a power-driven vessel underway but stopped and not making way (Rule 35(b)). It is also the signal for a vessel restricted in its ability to maneuver (Rule 35(c)). * **B) Two prolonged blasts:** This is the required fog signal for a vessel engaging in towing operations (the towing vessel) when her length exceeds 50 meters (Rule 35(c)). * **C) One prolonged followed by one short blast:** This is the required fog signal for a sailing vessel, a vessel engaged in fishing, or a vessel engaged in pushing (Rule 35(c)).
