3. Share a lock with other boats
Even if you have to wait for a few minutes for another boat that is approaching behind you, if they are heading in the same direction and planning on using the lock, make sure you wait and go in together. It helps to preserve water levels along the canals, plus it's a great opportunity to pop the kettle on for a nice cuppa while you are waiting for the lock to fill or empty.
4. Close the paddles and gates when leaving a lock
This is an important one, and if not done properly, can cause all sorts of problems for the canal and some very unhappy boaters. When you are finished in a lock, always moor up outside and go back to close the paddles and shut the gates. Not only does it avoid water flowing through and potentially draining the pound above the lock, but it also means that the next boater approaching the lock doesn't have to do extra work to prepare it for themselves.
5. Give way at bridges if the oncoming boat is closer than you
If you can see another boat approaching in the opposite direction, pull over to the right and let them through first. Never try to race to it first or try to pass beneath a bridge.
