Ok, it's cold and snowing out there, so here's something you may find interesting:

Did you know the Welland Canal? It's a canal on the canadian side of the St. Lawrence seaway connecting the Lake Erie to the Lake Ontario with a series of locks that enable the ships to by-pass the Niagara Falls. LR%20Welland%20Canal%20Map.jpg

Here's a well-made FAQ page about the canal: frequently-asked-questions-about-welland-canal

The average transit time for ships is around 10 hours but here's a time-lapse video of the transit taken from the bridge of a ship which show it in 10 minutes:

Fascinating. thanks for posting all three things. the FAQ's are very well done- will save lost of questions being posted. I was curious about how it seemed the ship slid its bow along the concrete to get lined up. turns out it was true.

Re: about that procedure, which is called "sliding the wall".

Nowadays, the locks were made of concrete with pneumatic fenders but an old-timer who used to work at the St. Lambert lock (the first one when entering the St. Lawrence seaway, in the Montreal area) told me that when they were made of wood (treated with creosote like railroad ties), they had to constantly cool them with water or they would catch in fire from the friction of the metal...

The same recordist has also posted this time-lapse recording made in Lake Superior:

He has also shot this time-lapse recording of a transit of the St. Clair River:

I think I have mentioned both of these before, but they're still fun to watch.

We have transited some large locks like those found in the Welland Canal. Several years ago we transited the locks at the American Soo, descending in the giant MacArthur Lock from Lake Superior to the St. Mary's River. The descent was quite rapid and also surprisingly free of turbulence. We were tossed two lines to hang onto during the descent. There was no charge. The MacArthur lock is 800-feet long and 80-feet wide. Our Boston Whaler REVENGE 22 felt quite insignificant in that lock space.

Thanks for these fantastic time lapse vids. Loved them. Big locks are always intimidating for we pleasure boaters. I once went through the Noordersluis in a 46-foot sailboat. This lock is part of the lock system in IJmuiden The Netherlands and normally not open to pleasure boaters as there are smaller lock available. The Noordersluis (North Lock) is 1,320-feet long and 165-feet wide so big boats can go from the Northsea to Amsterdam. Even though the elevation difference is small you are still a small bobber in a big body of water like that.

One of the things I most enjoyed watching was the operation of the bow thrusters and the currents that resulted and were very visible in the water.

Fascinating - thank you. "Sliding the wall" must make quite a noise.
