Web alarm clock for 9:33 p.m.
As you hand the job over, tell the next person that the 9:33 pm alarm marks the moment to carry the boat motor above the tide line. That gives them a clear cue instead of relying on a hurried verbal reminder. There is still time before 10:00 pm to choose a firm, dry spot and clear a safe path from the shore.
While the motor is being moved, this alarm page may sit behind another browser tab as you check messages or use a torch app. It should continue counting in the background, though some phones may restrict an inactive browser and delay the sound. Keep the browser running and your phone awake enough to alert you: if the page is closed or the phone sleeps, the boat motor reminder will not sound. Set the volume where the person taking over can hear it.
Near the water, voices, engines, karaoke, and waves can mask an evening alert, even as neighbourhood noise begins to ease by 9:33 pm. Put the phone close to the handover point but away from spray, and choose a strong, distinct alarm tone. A quick spoken confirmation between both people also prevents the signal from being mistaken for someone else’s notification.
