Question 47 GLI01 - Master-Unlimited Tonnage

The Correct Answer is D **Explanation for D (One prolonged followed by three short blasts):** The International Regulations for Preventing Collisions at Sea (COLREGs), specifically Rule 35(e), addresses the fog signals for vessels being towed. A vessel being towed (if manned and required to sound signals) must sound the signal required for the towing vessel (Rule 35(a) – one prolonged blast) immediately followed by the special signal for a vessel being towed: **three short blasts**. Therefore, the combined required signal is "One prolonged followed by three short blasts." **Explanation for why other options are incorrect:** * **A) One prolonged followed by two short blasts:** This is the required signal for a vessel (other than a power-driven vessel) that is Restricted in her Ability to Maneuver, a vessel constrained by her draft, a sailing vessel, a fishing vessel, or a vessel engaged in pushing and towing (when pushing/towing is part of a complex operation). It is not the signal for a vessel being towed. * **B) Two prolonged blasts:** This is the required signal for a vessel **underway but stopped** and making no way through the water (Rule 35(b)). * **C) One prolonged followed by one short blast:** This signal combination (prolonged, short) is often used in maneuvering and warning signals (Rule 34), but it is not the prescribed fog signal for a vessel being towed.
