Ship's Bells


1.The ringing of a bell makes an audible signal to mark time of the watch on board ship. One bell sounds for each half hour starting at the commencement of the watch. One bell means 12:30, two bells mean 1:00, three bells mean 1:30, and so on until 4:00 (eight bells). At 4:30 the cycle begins again with one bell.

2.Each vessel must carry a bell to sound when the vessel is anchored in fog.
