Web alarm clock for 9:30 p.m.
As you hand the evening catch over to the next crew, a 9:30 pm alarm can mark the moment when your part of the port delivery is finished. That leaves the incoming team a clear half-hour before 10:00 pm to unload, check the crates, and move everything away from the quay without relying on a shouted reminder.
Because the handover may continue while the screen is unattended, set the alarm on the phone or computer that will stay awake until it rings. Check the displayed time and volume before you pass responsibility across. If the browser is closed or the device sleeps, the alarm may not sound, so the catch delivery could miss its planned handoff. Keep the page open and the device connected to power if the shift change might run long.
Once the catch is safely with the evening crew, avoid letting small port chores take over the rest of your night. Put away wet gear, note anything the next shift needs to know, and prepare what you need for morning before leaving the harbour. Finishing those tasks soon after 9:30 pm protects a more useful stretch of sleep than postponing them until you get home.
