Taking a Narrowboat Through a Lock on England’s Canals
Navigating a narrowboat through a lock is one of the most quintessential experiences of canal cruising in England. Locks are an ingenious solution to the challenge of changing water levels along the canal network, enabling boats to traverse hills and valleys. While it may seem daunting at first, passing through a lock is a straightforward and rewarding process once you understand the mechanics.

Lock Training: Confident Canal Navigation with Blue Otter Boats
At Blue Otter Boats, we provide comprehensive lock training to ensure you feel at ease navigating one of the most iconic features of England’s canals. We will accompany you through the first set of locks, giving you one-to-one tuition and guidance until you feel at ease to go it alone.
Locks act as water elevators, raising or lowering your narrowboat between different canal levels. During your narrowboat holiday, our team will guide you through your first lock experience, teaching you how to safely operate paddles, manage water flow, and position your boat correctly.
Locks consist of a rectangular chamber with gates at either end. These gates can be opened or closed to control water flow, allowing the water level within the lock to match that of the canal on either side. The process can either raise or lower your boat, depending on whether you are traveling uphill or downhill along the canal.
Key safety tips include maintaining a clear distance from the white cill marker to protect the boat’s stern and closing paddles and gates after use to keep the canals running smoothly for everyone.
Whether you’re a first-time boater or need a refresher, our personalised lock training sets you up for a safe, enjoyable canal adventure with Blue Otter Boats.
How Locks Work
Locks consist of a rectangular chamber with gates at either end. These gates can be opened or closed to control water flow, allowing the water level within the lock to match that of the canal on either side. The process can either raise or lower your boat, depending on whether you are traveling uphill or downhill along the canal.
Preparing to Enter the Lock
As you approach a lock, slow down and assess its position and status. If the lock is empty and set in your favor—meaning the water level matches your direction—you’re ready to proceed. If not, you’ll need to prepare it by filling or emptying the lock chamber.
Secure your boat to the bank using mooring ropes while a crew member or fellow boater operates the lock paddles and gates. Locks are often manually operated, requiring the use of a windlass (a cranking handle which is provided onboard Blue Otter Boats) to turn the paddle mechanisms that control water flow. Always take your time to ensure the lock is safe and properly prepared before entering.
Entering the Lock
Once the lock is set, open the gates fully and carefully steer the boat into the chamber. Narrowboats are long and slim, leaving just enough clearance on either side, so steady control is crucial. It’s also helpful to have a second person on board or on the bank to guide and assist.
Once inside, close the gates behind you. Ensure the boat is securely positioned and held steady using ropes if necessary, especially if you’re in a deep lock where water turbulence can make the boat unstable.
Operating the Lock
If you’re going uphill, you’ll need to fill the lock by opening the paddles on the upper gates, allowing water to flow into the chamber. If heading downhill, open the paddles on the lower gates to drain the water. Water movement can be quite vigorous, so it’s important to open the paddles slowly to avoid jarring the boat.
Lock Gates about to close behind the narrowboat, which will secure the chamber and allow water to enter and raise the narrowboat to the next level.
As the water level rises or falls, adjust the ropes to keep the boat steady. Once the water inside the lock matches the level of the canal beyond, you can open the gates in the direction you’re traveling.
Exiting the Lock
Carefully steer the narrowboat out of the lock, being mindful of the tight space and any passing traffic on the canal. Close the gates and paddles behind you to ensure the lock is ready for the next boater.
A Shared Tradition and Water Conservation
Taking a narrowboat through a lock is not only a team effort but also a shared experience that enhances the charm of canal cruising. It’s an opportunity to engage with England’s waterways, learn about centuries-old engineering, and connect with fellow boaters. On popular routes like the Leeds & Liverpool Canal, where two narrowboats can pass through some locks at the same time, there’s a unique opportunity to conserve water and make the process more efficient.
Where possible, it’s encouraged to wait for another boat or pair up with other boats along the route. By doing so, you help reduce the frequency of lock usage and conserve water, which is essential for maintaining the flow of the canal system. Sharing locks also fosters a sense of camaraderie among boaters, turning a necessary task into a pleasant social interaction.
With practice, passing through a lock becomes second nature, and each shared lock is a reminder of the community spirit that runs through the heart of the canal network. Plus, each lock brings a sense of accomplishment and a deeper appreciation for the waterways you’re navigating.
