Expand your boating prowess with expert advice from Jon Mendez on manoeuvring a lock upstream safely and smoothly.

Boating inland presents certain challenges unlike those found on coastal voyages. One such challenge is locks. These structures are designed to enable boats to overcome sudden changes in water height, whether on a man-made canal snaking across hilly landscapes or a river with its own natural obstacles, such as swift rapids and falls. Locks generally comprise a lock chamber that can have its water level adjusted, gates on either end, and paddles or sluices that facilitate filling and emptying of the lock.

During this filling process, the boat(s) within the chamber may also shift forward and backward slightly due to water rebounding from the bottom gates. Monitor the lines securing your boat and adjust them as necessary. Once the water has reached the correct level, prepare to exit by tying up your boat, closing all paddles, and opening the exit gates. Always allow any swirling water to settle before moving on. Lastly, remember to close the gates behind you after passing through the lock, to facilitate the process for the next vessel. Remember, mastering the art of navigating locks is a crucial skill for any dedicated boater venturing inland.
