“Stand By” Onboard: How to Clarify an Instruction

A short instruction can leave important details unsaid. Learn how to clarify readiness, location and responsibility without guessing what another person intended you to do.

By Crew Rights CompassPublished 2 min read

“Stand by” commonly asks someone to be ready or available for what comes next. Its exact meaning depends on the task and the ship's procedures. It does not, by itself, tell a new crew member everything they need to do.

If you are unclear, clarify the missing detail with the person responsible. Familiar words can still leave an unfamiliar task.

Ready for what, and where?

In the IMO's Standard Marine Communication Phrases, preparatory instructions and instructions to carry out an action are distinct. A phrasebook is not an operating manual, and recognising a phrase is not the same as being trained for the task.

For everyday work, useful questions include:

  • What am I standing by to do?
  • Where should I wait or report?
  • Who will give me the next instruction?
  • How will that instruction reach me?

Where relevant, clarify whether you should be doing another assigned task while waiting. Do not invent the answer because a colleague appears busy.

Replace the nod with a clear question

Consider a fictional hospitality example. A supervisor says, “Stand by near the meeting room.” There are two meeting rooms, and the crew member has not been told which event is involved.

A useful response is: “Which meeting room, and what do you need me ready to help with?” After the explanation, the crew member can confirm the location and task in their own words.

That is ordinary face-to-face clarification. It is not a radio script or a substitute for required communication procedures.

Avoid saying you understand when you have only recognised a few words. Asking for the missing piece is more useful than repeating an unclear sentence confidently.

Say what you can actually do

If you lack the training, equipment, access or information required for an assignment, tell the responsible person. Being available does not establish competence or authorisation.

If two instructions conflict, identify the conflict and ask for it to be resolved through the appropriate supervisor. If a hazard arises, follow the vessel's reporting and emergency arrangements without waiting for an informal conversation to finish.

For recurring confusion, ask for a short briefing before the next task. A written location or reference can help when names sound similar.

Takeaway: understand the task, place and next step. “Ready” should describe a shared understanding, not a guess.

Quick check · no score kept

In an ordinary face-to-face work conversation, “meet aft later” leaves you unsure. What would make it clearer?

  • Ask for the deck, meeting point and time
  • Nod and hope the group chat explains it
  • Use last week’s meeting point
Show the explanation

The article’s answer: Ask for the deck, meeting point and time. Specific questions prevent avoidable confusion. This example is everyday conversation, not a radio procedure or substitute for safety training.
