Online alarm clock for 1:48 am
Finish checking the nets before the Bay of Islands tide turns, then set the 1:48 am alarm as the cue to pack up and leave. It gives you a clear endpoint while you secure the last float, gather your gear and prepare to head off, rather than letting the job drift past 2:00 am.
Match the alarm sound to where the net check will end. A gentle tone may be enough beside a quiet launch or inside a cabin, while a more persistent sound suits a breezy shoreline where water and rigging can mask it. Set the volume beforehand and leave the alarm audible. Because this browser alarm cannot sound after the browser closes or the phone goes to sleep, the nets could keep you occupied past your planned departure; use a separate alarm as backup.
As the net work winds down, pause and listen to the Bay around you before relying on the chosen tone. Background noise can shift quickly at this hour: an engine may stop, wind may rise, or gear being loaded may briefly cover a softer signal. Keep the phone close to your packing area, with its speaker uncovered, so the 1:48 am alert remains noticeable amid those changes.
