How to use the online timer
Staying beside the narrowboat as it works through a flight of locks makes a fifty-nine-minute countdown useful for keeping the whole passage in view. You can watch the paddles, ropes and water levels without repeatedly checking the clock, while allowing for the steady rhythm of opening gates, moving into each chamber and securing the boat again.
As the boat moves from one lock to the next, the alarm needs to remain noticeable amid running water, engine noise and conversation on the towpath. Headphones can quietly take over the sound without their wearer realising it, so the screen remains a useful visual reference while you stay near the chamber. Keeping the device where it can be seen also avoids relying on an alert masked by a jacket, wind or the clatter of a gate.
While you remain with the boat through the cascade, consider who else will hear the signal when the final lock is near. A loud alert may startle a crew member handling a rope or disturb people waiting beside the next gate, particularly on a busy British canal. Positioning the device close enough for its owner to notice, with a moderate tone, keeps the ending clear without making the whole lock flight part of the announcement.
Common questions
What could make this countdown too short or too long for taking a narrowboat through the lock flight?
Queueing boats, low water levels and instructions from a volunteer lock keeper can extend the passage. A clear flight with gates already set may let the boat pass through sooner.
What should I do if the narrowboat clears the cascade before or after the set period ends?
If it clears early, silence the alert before it affects people around the mooring or towpath. If the passage runs late, keep attending to the boat and treat the elapsed signal as a reference rather than a reason to rush the remaining gates.
