Web alarm clock for 4:21 a.m.
As you hand the night boat’s catch over to the next crew, a 4:21 am alarm can mark the moment your part of the unloading should end. It gives you a clear cue to pass along the tally, point out which crates still need moving, and leave the landing area settled before 5:00 am. That helps the changeover feel deliberate even when everyone is tired and the quay is still dark.
While you finish unloading the catch, keep the alarm page visible and check your phone’s silent setting before relying on the sound. Silent mode may suppress the alert, and this browser alarm also cannot warn you if its page is closed or the phone falls asleep; either issue could leave the catch handover waiting without a signal. Set the volume to a sensible level and keep the phone powered, awake, and near enough to notice.
Before leaving the catch with the incoming crew at this hour, choose a spot for the phone that will not carry the alarm through the whole house. A short vibration against a folded cloth can be noticeable nearby without rattling a table, and a moderate tone is less likely to wake sleeping family members. At 4:21 am, agree who will silence it so the sound does not continue after the handover.
