Canal locks are a given on a canal boating trip, and on our recent canal cruise in Alsace aboard a Nicols boat, we must have done at least 40 over the course of the week. At first, we were total amateurs, but after a couple of days, we figured out a good system to safely and efficiently pass through the locks. What are locks, how do they work, and what are some tips for operating them?
Tips for going through canal locks in France and what it’s really like (VIDEO)
Before our canal trip, I had zero experience with locks. I vaguely knew what they were, but the specifics were a little fuzzy. I figured a lock keeper would help us out and that we’d figure it out easily enough. Well, that was mostly the case as far as figuring it out goes, but there were no lock keepers anywhere along our route. Much to my surprise, we looked like pros by the end!
So first, what is a canal lock?
Simply put by Wikipedia, “a lock is a device used for raising and lowering boats, ships and other watercraft between stretches of water of different levels on river and canal waterways.” So depending on what part of the canal we were on and which way we were traveling, sometimes we’d go through a lock that would raise us up and other times we’d gently be lowered down to the next stretch of canal. The basic process is the same.
There are several different types of locks but for this post I’m talking about automatic pound locks, the only kind we encountered. This means doors of the lock opened and closed on their own once they were activated and we didn’t have to crank the doors open or shut. All that we had to do once we were safely in the chamber and secure was lift a lever which triggered the doors to close and start the process. It was just us — no lock keepers at all.
How does it work?
In a nutshell, the lock’s gates open up when it’s all clear for the boat to enter (and we were shown a green signal on the sign before the lock). Then it was our turn to slowly enter the chamber toward the closed gate at the end of the chamber. Once we secured our boat, we lifted the blue lever which then told the gates to close behind us and form a watertight seal. Then the opposing door at the other end of the chamber would either open slightly to let water out if we were heading downstream (to lower us) or allow water to gently rush in from above to fill the chamber, thus raising us up.
This whole process can take 10-15 minutes and even longer if the lock is not ready for you. Luckily, we only had to wait a handful of times since there weren’t many boats on the canal. On one particular stretch of the canal, we were given a remote to signal the lock a little bit in advance to minimize the wait. That way, if it wasn’t ready for us, it would know we were coming and open its doors.
Tips for operating a canal lock
It’s only natural to be a little anxious ahead of time if you don’t have any lock experience. I was. I had no idea what it would be like and was scared we’d maybe damage the boat or mess something up. Or embarrass ourselves in front of passersby. In reality, it’s all very slow, calm and controlled and there’s no reason to be nervous.
Here are a few things to keep in mind when going through canal locks:
- Always read/watch all the materials given to you by Nicols or the company you booked with. They’ll have tips specific to your area that you’ll want to know. In the name of safety, take a look at everything ahead of time and speak up if anything is unclear.
- There’s no rush. Always go slow. The doors won’t shut and water won’t come in or be let out until you want it to. Before actually operating a lock, I was a little apprehensive thinking, “Oh no what if we’re not ready and the doors shut or the water comes in too fast.” My fears were unfounded and once I learned how locks worked, I realized I had nothing to worry about. You’re the one who activates the lock via a lever. Nothing happens until you tell the lock to start filling or emptying. Yes, if you take all day, boats waiting behind you at busy times might get flustered, but generally speaking, you slowly enter the lock and can take your time securing your boat. Once you get the hang of it, the process will go more quickly.
- Locks have operating hours. If you want to get an early start and leave at 6am, you may want to rethink that. Likewise if you want to continue on until sunset at 9pm during the summer, that won’t work either. Most of the locks on our route opened at 8am and closed by 7pm, so plan accordingly.
- Pull all the way forward in the lock chamber. It’s best to do this for two reasons: 1) So another boat can come in behind you. By pulling all the way up, you’re leaving room for another vessel to pass through the lock with you. 2) It’s easier to steer straight out of the chamber if you are already close to the exit gates. If you’re at the back of the chamber, you have to steer straight out and go through a good 10 meters of wall space. This means there’s more of a chance for you to bump into the wall.
- Some locks beep while others have alarms. To activate the lock and start the water flowing, you have to lift up the blue lever. Right next to that blue lever is a red alarm lever. Our first 20 locks all beeped to let us know doors were opening/closing. It was a regular beeping sound that lasted about 30 seconds and we were used to it. Then, for the next stretch of canal this beep changed to an alarm and it startled us at first. I thought I mistakenly pulled the red alarm lever by accident! So just know that sometimes the alert will be a little beeping noise and other times it’ll be an alarm. It stops by itself but caught us by surprise at first!
- Work as a team. For beginners, it’s best to have 3 people for each lock if there’s no lock keeper. There’s the captain behind the wheel and then two deckhands, one at the bow and stern of the boat to handle the lines. It can be done with 2 people but if you’re new at this, it’s best to have 3.
And now for some visuals… 😉

P.S. We used a Joby GorillaPod to secure our iPhone for all the timelapse videos. It’s a solid product that I highly recommend. Here’s what it looks like:
