We started our trip from Racine, Wisconsin to Mobile, Alabama with some trepidation about going through locks. After a lot of reading, we still had some lock anxiety. All that melted away after a few, and now we think we have a pretty good idea what we’re doing.
After going through more than 20 locks as high as 57 feet, we think we have it down. I hope this helps ease your anxiety.
Step One: Call the Lock Master. Never assume he knows your intentions. It’s best to call as far ahead as possible. If he’s busy with barge traffic, he’ll let you know and you can slow down or stop for lunch. Sometimes he’ll say “come on ahead, I’ll have it ready for you”. Either way you save time and fuel. Important: All crew on deck must wear personal flotation devices (PFD’s). Ialso recommend a Cubs hat.
Step Two: You will also know by now if there’s a required side to tie on. Usually they let us tie on either side, so we took our preferred starboard tie. Have plenty of fenders out and just loop your midship line over the bollard. Do not tie to the bollard, just put your line around it and back to the boat. This is a floating bollard which floats down, or up in its channel as you move. Keep an eye on it and be ready to release your line in case it jams. Ours never had a problem. We only had two fixed bollards during the trip. In that case you have to adjust your line as the boat goes down or up. Floating bollards are easier, but even the fixed type aren’t really a challenge, they just take more attention during the process.
Step Three: The lock master will close the doors behind you, and signal when the water level is about to begin changing. This is all done with valves and all you do is tend your boat. Here you see Kristi using a boat hook to keep our boat straight. I’m doing the same at the stern. This is necessary because our sailboat tapers at both ends. Boats with straighter sides tend to lay along the wall better.
Step Four: After the giant whirlpool stops… Just kidding! It’s really not very dramatic, the water level just slowly goes up or down and you float with it. Depending on several factors this takes around 10 – 20 minutes in most cases. When the doors open in front of you wait for the lock master’s signal that it’s safe to move. If you’re sharing the lock it’s simply first in, first out unless you’ve made other arrangements. There typically is some turbulence on the downstream side,but it’s not terrible. Just power through it and go on to the next lock.
Here’s a look around just after we dropped 31 feet.
I always half expect King Kong to be on the other side of these doors.
And finally, a boater who obviously did it wrong. Just follow the simple rules above and you can avoid this.
Bonus Step Five: Your fenders will get very dirty in the locks. Barkeeper’s Friend will clean them very efficiently.
