How to Navigate Canal Locks Safely

Canal locks are an essential part of Britain’s waterways and a unique feature that adds charm to the experience of travelling by boat. For those planning narrow boat holidays, understanding how to use locks safely and confidently is an important skill. While they may seem daunting at first, with a little knowledge and teamwork, navigating locks can become one of the most enjoyable parts of the journey.

 

How do canal locks work?

 

Locks are used to raise or lower boats between stretches of water at different levels. Each lock is an enclosed chamber with gates at both ends. Water levels are controlled by sluices or paddles that can be opened or closed using a winding handle called a windlass.

 

When you approach a lock, you will either need to fill it or empty it so that the water level matches the level your boat is currently on. Once the levels are equal, the gates can be opened and your boat can safely move in or out.

 

If you are new to canal boats hire, it is worth spending some time watching other boaters go through the process before trying it yourself. Most boaters are friendly and happy to offer advice to beginners.

 

How to enter a canal lock safely

 

Approach slowly and steadily, keeping the boat under control. It helps to have one person steering and another operating the lock gates. If you are travelling with others, agree on hand signals or simple instructions so that communication is clear.

 

Before opening any gates or paddles, always check that the lock is set in your favour. This means the water level inside the lock matches your current level. If it does not, and you can’t see another boat approaching the lock you will need to fill or empty it using the paddles. Open them gradually to prevent water from rushing in too fast, which could make the boat move unexpectedly.

 

When entering the lock, steer carefully into the centre and keep the boat away from the sides. For wide locks, use ropes to hold it steady against the lock wall as the water level will change.

 

How to operate a canal lock

 

As the water rises or falls, keep a close eye on the movement of your boat. The person at the helm should adjust the tiller as needed to maintain balance and prevent the boat from drifting or catching on the lock walls, and when descending a lock pay close attention to keep the stern of the boat clear of the ‘cill’ as the lock empties.

 

For those taking narrow boat holidays, teamwork is key. One person can manage the paddles while another monitors the boat. Open and close the paddles slowly and evenly on both sides to avoid turbulence inside the lock. When the water level has equalised, the gates can be opened.

 

It is always safer to use both hands when winding the paddles, and to stand well clear of the gates and moving parts. Locks can be heavy, so take your time and never rush the process.

 

How to exit a canal lock safely

 

Once the gates are open, steer gently out of the lock, keeping a steady pace. Make sure the boat is clear before closing the gates and paddles behind you. Leaving the lock ready for the next boater is good canal etiquette. NEVER leave paddles raised as this will drain the pound of water.

 

If you are part of a group travelling together, allow one boat to pass through at a time, unless you are navigating wide locks where two boats can fit two abreast.

 

 

Navigating locks safely is a big part of the adventure that comes with narrow boat holidays. It encourages teamwork, patience, and a closer connection with the canal’s history. The original lock designs date back hundreds of years and still operate much as they did when Britain’s waterways were first built.

 

For those new to canal boats hire, locks may seem like a challenge at first, but after a few tries they become second nature. With care, communication, and respect for the waterway, you can travel through locks safely and enjoy the slow, peaceful pace of life on the canals.
