Question 47 UFV01 - Master - Uninspected Fishing Vessels

The Correct Answer is D **Explanation for Option D (Correct Answer):** The required fog signal for a vessel being towed, if the vessel is manned and the tow is considered a "manned tow" (meaning the vessel being towed is not considered a "dead tow" and is maintaining a watch), is prescribed by Rule 35(e) of the International Regulations for Preventing Collisions at Sea (COLREGs), which applies to both International and Inland waters (as Inland Rules largely mirror or incorporate COLREGs Rule 35 for this specific signal). Rule 35(e) states that a vessel being towed may give, in addition to the signal required of the towing vessel (a prolonged blast), a signal of **one prolonged blast followed by three short blasts**. This signal is intended to identify the vessel being towed and indicate its nature to other vessels, serving as an additional warning. **Explanation for Incorrect Options:** * **A) One prolonged followed by two short blasts:** This signal (Rule 35(b)) is the required fog signal for a power-driven vessel underway but stopped and making no way through the water (a vessel "lying to"). It is not the signal for a vessel being towed. * **B) Two prolonged blasts:** This signal (Rule 35(c)) is the required fog signal for a vessel that is not under command, a vessel restricted in her ability to maneuver, a vessel constrained by her draft, a sailing vessel, or a vessel engaged in fishing or towing (if the length of the tow exceeds 200 meters). While a towing vessel might use a prolonged blast, two prolonged blasts are not the specific identification signal for the towed vessel itself. * **C) One prolonged followed by one short blast:** This signal is not a standard required fog signal for any specific category of vessel under COLREGs Rule 35. Standard signals use combinations of prolonged and short blasts, but this sequence does not correspond to the required signal for a manned vessel being towed.
