Rules of the Road · Restricted Visibility Signals
A 120-meter vessel is at anchor in restricted visibility. How must she supplement the forward bell signal?
- AShe sounds one prolonged blast after the bell
- BShe sounds three short blasts after the bell
- CShe strikes a gong rapidly in the after part immediately after ringing the forward bell✓ Correct
- DShe sounds a whistle signal in addition to the bell
Explanation
Rule 35(g) states that for vessels 100 meters or more in length, the bell is rung rapidly for 5 seconds in the forepart of the vessel, and a gong is struck rapidly for 5 seconds in the after part immediately after the bell. This gives anchored vessels in fog a forward and aft audio signal so approaching vessels can determine their aspect.
