On Watch

Under way.

The watch procedure and the references you'll want one hand away from the wheel.

Keeping Watch
Stay on board
  • Use an attached harness when alone on watch and always keep it on when on deck.
  • If alone, ask next watch for help with sail changes or manoeuvres.
Stay afloat
  • Inspect bilge and be attentive to bilge pump cycling.
  • Inspect engine room.
Stay out of the way
  • Keep a good lookout.
  • Use radar and AIS to determine risk of collision.
  • Alert skipper early about potential risk.
Stay the course
  • Keep on course.
  • Monitor chart for obstacles and markers on the course.
  • Maintain sail trim.
  • Listen to radio traffic and warnings.
  • Be alert to engine sensors, e.g., temperature, oil, and battery charging and status.
  • Log any departure from plan or routine.
Warning!
  • When in doubt or if action is required, alert skipper.
  • Do not nap, sleep, or stay below longer than necessary for the ship business. If you cannot stay alert, wake up the following watch.
The Book · checklist side

Keep the watch card at the helm.

The same On Watch reference, waterproof. The book flips two ways — procedures from one cover, checklists from the other. Mount it within arm's reach of the wheel so the oncoming watch has it in hand, day or night.
