Question 50 GLI07 - OUPV

The Correct Answer is B A continuous sounding of a fog whistle (or any prolonged sounding device) by a vessel indicates that **a vessel is in distress**. This signal is internationally recognized under the International Regulations for Preventing Collisions at Sea (COLREGs), Rule 37 (Distress Signals), and is also codified in Inland rules. A continuous sounding device is specifically listed as one of the definitive signals used to indicate distress and the need for assistance. ### Why Other Options Are Incorrect: **A) A request that the draw span of a bridge to be opened:** Bridge opening requests are typically made using specific short and long blasts (e.g., one long blast followed by one short blast or several short blasts, depending on the waterway and local rules) but never a continuous blast, which is reserved exclusively for distress. **C) That the vessel is anchored:** Under reduced visibility (fog), a vessel anchored must signal its position using rapid ringing of the bell for about 5 seconds at intervals of not more than 1 minute, sometimes supplemented by a gong (for vessels 100 meters or more). A whistle may also be used to give an additional warning, but it would be one short, one long, and one short blast (COLREGs Rule 35(f)). It is not a continuous sounding. **D) A vessel is broken down and drifting:** While a vessel broken down and drifting may well be in distress, the signal itself specifically indicates "distress" (Rule 37), which encompasses being broken down, sinking, or otherwise in peril. The signal isn't for merely drifting; it is an urgent plea for help.
