Question 47 GLI05 - Master or Mate of LT 200 GRT

The Correct Answer is D **Explanation for Option D (Correct):** The International Regulations for Preventing Collisions at Sea (COLREGs), Rule 35(e), specifies the fog signal for a vessel being towed or, if the length of the tow exceeds 200 meters, for the last vessel towed. A manned vessel being towed must sound **one prolonged blast followed by three short blasts** at intervals of not more than two minutes. This signal clearly identifies the vessel as being restricted in its ability to maneuver because it is being towed. Since the question asks for the signal required for "BOTH INTERNATIONAL & INLAND," and Inland Rules generally conform to International Rules for this specific signal, D is the correct requirement. **Explanation for Other Options (Incorrect):** * **A) One prolonged followed by two short blasts:** This is the required fog signal for a power-driven vessel **underway but stopped and making no way through the water** (COLREGs Rule 35(b)). It is also the signal for a sailing vessel or a vessel restricted in its ability to maneuver (including vessels engaged in towing, provided they are not sounding the towing signal). It is not the signal for the vessel **being towed**. * **B) Two prolonged blasts:** This is the required signal for a vessel **at anchor** to announce its presence when hearing the fog signal of an approaching vessel (Rule 35(g)). It is not the signal for a vessel being towed. (The standard anchor signal is rapid ringing of the bell). * **C) One prolonged followed by one short blast:** This signal is not a standard fog signal defined in COLREGs Rule 35. The signal "one prolonged blast" followed by specific short blasts always signifies a particular operational status.
