Ship's bell strike explained!  On a ship, there are four hour watches where some poor sap has to steer the vessel or stand out in the cold watching for mines, icebergs, Cubans or what have you.  To keep these poor guys company and maybe keep them awake, a bell strikes every half hour and lets them know how far into the watch they are.  Traditionally, watches start at 12:00, 4:00 and 8:00 so:

At  12:30, 4:30 & 8:30   = 1 bell,
        1:00, 5:00 & 9:00   = 2 bells,
        1:30, 5:30 & 9:30   = 3 bells,
        2:00, 6:00 & 10:00 = 4 bells,
        2:30, 6:30 & 10:30 = 5 bells,
        3:00, 7:00 & 11:00 = 6 bells,
        3:30, 7:30 & 11:30 = 7 bells,
      12:00, 4:00 & 8:00   = 8 bells
