The glass striking system (also called ship's clock strike or ship's clock chimes) is a special way of telling time on ships that has its roots in maritime tradition. The system is used to divide the watches on board and dates back to the time when hourglasses were used to keep track of time.

How do the glass beats work?

  • A ship's watch usually lasts four hours.
  • To keep track of time, sailors turned a 30-minute hourglass.
  • Each time the glass was emptied (every 30 minutes), the ship's bell struck once more.
  • The glass beats go from 1 to 8 beats, after which they start all over again.

Overview of the glass strokes in a shift:

  • 1 glass = 00:30 (after half an hour)
  • 2 glasses = 01:00
  • 3 glasses = 01:30
  • 4 glasses = 02:00
  • 5 glass = 02:30
  • 6 glass = 03:00
  • 7 glass = 03:30
  • 8 glasses = 04:00 (end of shift)

When 8 glasses have been knocked, it means that a new shift begins.

Example in practice:

If it's 06:30, the ship's clock will strike 3 glasses (because we are an hour and a half into the new shift from 04:00-08:00).

This system made it easy for sailors to know how far into the watch they were without having to look at a clock.

Have you ever seen or heard a ship's clock strike glass before? 😊
