Online alarm clock for 2:17 am
As you hand the night search to another coastguard watch, set the alarm for 2:17 am so the changeover happens at the agreed moment. That leaves the incoming team time to confirm the search area, launch details and radio channel before 3:00 am, without turning the handover into a rushed exchange.
For a coastguard changeover, choose the alarm sound to match how easily you are likely to notice it. A softer tone may suit a quiet operations room, while a persistent one makes more sense if radios, engines or conversation could mask the first notes. Set the volume before relying on it and leave the alarm page active. This browser alarm will not alert the coastguard team if the page is closed or the phone goes to sleep, so use a separate backup for a critical callout.
Before the replacement crew steps outside at 2:17 am, allow a moment to adjust from the indoor air and check how damp the night feels. Coastal humidity can leave jackets, rails and equipment surfaces wet even without obvious rain. Keep a dry layer within reach, wipe moisture from anything that needs a firm grip, and avoid leaving briefing papers exposed while the search details are passed across.
