Before you take command

A captain keeps checking the assumptions behind a plan. If a forecast changes, a return takes longer, or equipment is unreliable, the plan may need to change too. Preserving options and communicating clearly are part of a successful watch.

  1. 1.Observe
  2. 2.Identify the hazard
  3. 3.Check what is missing
  4. 4.Choose a plan
  5. 5.Communicate
  6. 6.Reassess

Worked example: 3 NM at 6 knots takes 30 minutes each way. Add the return and any stop before deciding whether the plan has enough margin.
