How to use the online timer
Staying beside a narrowboat as it works through a flight of locks means watching the water level, gates and paddles rather than wandering away. A countdown of thirty-seven minutes gives the passage a useful boundary while leaving enough attention for ropes, nearby crews and changing conditions.
Keeping the boat in sight also makes it easy to glance at the remaining time between each stage. If the browser tab moves into the background, the countdown continues; returning to it shows the elapsed time rather than restarting the interval. A muted phone or power-saving setting may prevent an audible alert, so the visible display is the more reliable check beside the lock.
Following the boat from chamber to chamber provides natural points for comparing progress with the countdown. A mechanical timer with a ring can be set only approximately, while the on-screen reading tracks individual seconds and makes a short delay at one gate visible. Canal traffic, water levels and assistance from another crew can alter the passage, so treat the finish as a checkpoint rather than a prediction.
Common questions
What could make a thirty-seven-minute passage through the lock flight take longer?
Queues, slow-filling chambers or a gate that needs extra care can extend the passage. Keep attending to the boat and use the expired countdown as a prompt to reassess progress.
What if the narrowboat clears the locks before the thirty-seven-minute countdown ends?
Stop the countdown once the boat is secure beyond the final gate. The unused time simply shows that water levels, traffic and crew coordination allowed a quicker passage.
