How to use the online timer
While the narrowboat works through a flight of locks, you may spend fifty-one minutes waiting beside the chamber rather than doing another job. That pause can cover several steady passages when the pounds are full and each crew ahead moves promptly, but a busy British canal flight may leave the boat sitting between gates for much of the interval.
From the towpath, with nothing to occupy you except watching the boat progress, a phone can appear inactive long before the countdown finishes. The display going dark does not normally stop the timer, so there is no need to keep waking it beside every lock. Keep the phone somewhere dry and audible, especially when water, engines and conversations around the gates could mask the alert.
As the narrowboat reaches each chamber, judge the remaining wait against actual lock movements rather than the hopeful pace suggested at the start. A mechanical timer with a ring can be knocked while handling a windlass, and its broad markings make small adjustments uncertain. A digital countdown preserves the intended interval precisely, while the number of locks completed shows whether queues, slow paddles or low pounds are stretching the passage.
Common questions
What could make a fifty-one-minute lock passage take longer on a UK canal?
Queues of hire boats, slow-filling pounds or a crew closing gates carefully can extend the passage. If the countdown ends mid-flight, keep the boat secured and use the lock sequence, not the alert, to decide when to move.
What if the narrowboat clears the locks before fifty-one minutes have passed?
An empty flight, favourable water levels and an experienced crew can shorten the passage. The remaining time can simply be disregarded once the boat is safely beyond the final gate and the lock has been left correctly.
