Question 47 GLI06 - Master or Mate of LT 100 GRT

The Correct Answer is D **Explanation for Option D (Correct Answer):** The required fog signal for a vessel being towed, whether under the International Regulations for Preventing Collisions at Sea (COLREGs) or the Inland Rules, is detailed in Rule 35 (Sound Signals in Restricted Visibility). According to Rule 35(e): * **A vessel being towed** (or, if more than one is towed, the last vessel of the tow) shall, at intervals of not more than 2 minutes, make the signal **one prolonged blast followed by three short blasts** (— • • •). * This signal is made immediately after the towing vessel makes its own signal (usually one prolonged blast). **Explanation for Other Options (Incorrect):** * **A) One prolonged followed by two short blasts (— • •):** This is the required fog signal for a vessel **not under command**, a **vessel restricted in its ability to maneuver**, a **sailing vessel**, a **vessel engaged in fishing**, or a **vessel engaged in towing or pushing where the signal (—) is impractical**. It is not the signal for a vessel being towed. * **B) Two prolonged blasts (— —):** This is the required fog signal for a **vessel at anchor** (in addition to the rapid ringing of the bell) or a **vessel aground** (in addition to the bell and gong signals) to indicate a warning of their position. * **C) One prolonged followed by one short blast (— •):** This signal is not a standard required fog signal listed under Rule 35 for any specific category of vessel in restricted visibility.
