Question 47 UFV02 - Mate - Uninspected Fishing Vessels

The Correct Answer is D **Explanation for Option D (Correct Answer):** The required fog signal for a vessel being towed, when it is manned (which is assumed for a large tow that would be the primary concern under the Rules), is mandated 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 generally mirror or adopt the relevant COLREGs regarding sound signals). Rule 35(e) states: "A vessel being towed may at intervals of not more than 2 minutes, make at least one prolonged followed by three short blasts." This signal is made immediately following the towing vessel's signal (which is usually one prolonged followed by two short blasts, but must be distinct from it). **Explanation of Why Other Options Are Incorrect:** * **A) One prolonged followed by two short blasts:** This is the required fog signal for a **vessel restricted in her ability to maneuver, a vessel constrained by her draft, a sailing vessel, a fishing vessel, or a towing vessel** (when the tow signal is not used). It is the signal made by the vessel doing the towing, not the manned vessel being towed. * **B) Two prolonged blasts:** This is the signal for a **vessel not under command** (NUC) or a **vessel making way but stopped** (in some contexts, though this is often simplified to one prolonged followed by two short in modern interpretation of 35(b) for vessels that are stopped but making way). However, it is explicitly **not** the signal for a vessel being towed. * **C) One prolonged followed by one short blast:** This signal is designated for a **pilot vessel** engaged on pilotage duty (Rule 35(g)).
