just keep her in the middle

That was really fun to watch.
As accurate as they were, I'm amazed those tiny little channel markers survive for long. I got scared at the end when it all turned to night, but I suppose they know how to maneuver in the dark just as well. The question is, do the bass fishermen?
Maybe, if they just installed a rail system, they could go over the falls instead of around them. Make it one enormous slide. The weight of the descending freighter could help haul the weight of the ascending freighter up. But, just think, if it was a bass boat on the ascending track, we could be fishing for bass on the moon.

Will, my wife swears sailing works just fine til we get off the track. She says that is what the keel is really for, to keep the boat in the track!
Tell that to the railroad companies. "The heaviest trains in the world carry bulk traffic such as iron ore and coal. Loads can be 130 tonnes per wagon and tens of thousands of tonnes per train." https://en.m.wikipedia.org/wiki/Rail_freight_transport
We just need to beef the rails up a little. Then "WEEeeeee!"

No. Of course, it's on my list. My wife has talked about taking Dragonfly through the canals to the GoM. It took her parents 50 years of marriage before they could go.

Keel? What keel? We don’t need no steeenking keel!
Edit: PS - it’s the hard things that keep us in the track. See that reef in the upper left of my photo? Invisible at mid tide.
Haha! Yes, we tri-hull people like to run with the fast pack!Keel? What keel? We don’t need no steeenking keel!

Do the board and rudder kick up on that dragon fly?
Yes they do. Like “curb feelers” I know when it’s too shallow. 6.5’ draft centerboard down all the way. 3.5’ minimum draft. Centerboard and rudder are both buoyant and swing aft so they pop up easily and quickly when needed. They are cleated to a spring-release mechanism. The prop and shaft are protected by a skeg so the boat can dry out on mud or sand without damage, but point loads like debris or rocks are still a concern.

The video of the Whirlpool Rapids, only a couple of miles up river of my house. Have been up there in a ski boat numerous times, but I was a lot younger then, and wobbly pops were involved. Dangerous waters, but jetskis go there all the time.
Great steelhead fishing this time of year, Niagara river has good fishing all year.
Cheers

It's funny, but they don't really keep it in the middle. They run the ship along the wall to get into the locks. I used to work on a cruise ship that ran the length of the St. Lawrence river. Fun to watch the big lakers in the locks; amazing skill fitting a ship that size into a box only a few feet bigger than it.
I think it is a foot bridge for lock personnel to get from side to side.

the crane looking arm you ask of has a huge, 6/ 8 inch steel cable in it that is there so that a ship can never ever run into the lock doors.

What if a volume of water roughly 75 feet x 25 feet x 1000 feet was suddenly let loose?
I don't. know about the Welland Canal, however , on the Erie Canal the lock doors are configured so that water pressure pushes the closed.
Imagine the scene if those lock doors broke open. A 25 foot wall of water would enter the lock. And this lock is much smaller than the ones on the Welland.
