When using whistle signals for launching lifeboats, what does one short blast mean?

• A. Dismissal from drills (drill is over, secure all boats).
• B. Begin lowering lifeboats.
• C. Proceed to muster.
• D. Standby.

Answer: (A)

One short blast is the dismissal signal. It tells the crew that the drill or lifeboat launching exercise is finished and that all lifeboats should be secured and normal operations resumed. It marks the end of the procedure, so people stop launching actions, return to their stations, and stow gear as required. Other signals indicate actions like standing by, muster, or beginning lowering, but a single short blast specifically cues completion and securing of boats.
