Wayfarer, Dave, thank you for the terrific videos of ore ships on the Great Lakes and the Canals. Just goes to show how much we live in our own bubbles. I had no idea that there were as many canals and narrow waterways that were navigated by BIG ships.
Can’t thank you enough for the very interesting information.

Thanks for stroking my ego! lol.
You will find that most canals which handle LARGE boats have at the openings 'bumpers' which allows the boat to hit, with no damage to either, to help them line up on entry.
Once in the lock, if you look, you will see the marks on the walls of where some have hit.
While I know that a captain of a big boat must have nerves of steel, it is probably more often when a pilot steps aboard. The captain knows that if the pilot makes mistakes, he is still responsible.
I get to be my own pilot. It's usually my favorite part of the job, but is frequently the part that makes me want to crawl into bed and never get out again, lol.
Also, you might be surprised at how many docks and walls DONT have any kind of fendering. There are so many sharp 90 degree corners, so much jagged sheet piling, you'd think they were trying to sink me. Sometimes the angle iron that USED to hold some nice big friendly pieces of timber are all that's left, and Now it's just a rail of sharp steel... There's one dock we go to regularly that would be fine without fendering, but to be nice, they hung up some nice big fluffy tractor tires. I appreciate the sentiment, but the brackets that they hung them from were sharp steel angle iron chunks that stuck out about 90 degrees from the dock. I'd hit them way before I touched the tires. They're effectively can openers
I conned a destroyer through the Suez Canal, and we were advised that getting too close to either bank would cause a rapid increase in the size to the bow wave throwing us toward the center - a bad thing when encountering an oncoming vessel. Since we were escorting the first US Navy aircraft carrier to pass through there in many years, all other traffic was halted, and soldiers lined the entire 110 miles of the canal. I took that same destroyer through the Panama Canal the next year.
Years later after riding the battleship USS New Jersey through there, I conned the battleship Iowa through the Panama Canal where there was about zero clearance in the locks because the thicker rubber fender had been added many years after the design of the battle ships which were 108 feet wide while the original canal clearance was I think about 110. We played fire hoses over the side to prevent starting fires due to friction. I n one lock the pilot told me to go ahead for five knots after the gate opened - nothing. We then rang up 10 knots - nada. I heard the pilot call for a "flush" and soon realized that he was having the lock flooding valves opened behind us because our flat bottom and straight hull sides FILLED the lock which prevented the four big screws from pulling water aft around the hull. As soon as we began to move, I ordered us back to five knots so as not to run our 86,000 tons out of the lock yanking the diesel mules into the drink.
Several years later, I achieved the 3rd fasted transient to the Panama Canal in a 105-foot long crew boat. The pilot would have me slip in ahead of slowly moving ships just before their bows cleared the lock sills getting us into the front of the lock. Then as the doors began to open, quite contrary to shipping practices, he had me cast off from the side of the canal where we moored and head for the opening. I had all four Detroit 12V92TAs at full throttle just BEFORE to gate was open enough for our beam and roared out of there to the next lock. That pilot was a hot dog with a willing accomplice!
You've got some great sea stories, Rich
I have a similar situation happen somewhat regularly when coming into Manistee, MI. It's a skinny little channel, but it's mostly a straight shot, and there's loads of wind protection, so it looks harder than it is. When we come in with heavier loads, there's a point when we effectively take up the entire river. When we get about halfway through the Maple St. Bridge, there's only about 10 feet on either side, and about 4 feet under us in the middle of the channel, but at the turns of the bilge, she's inches off the banks. The effect is that there's really nowhere for the water to go, and we come to a stop. I'll slowly ramp up the engine speed, and even at full ahead, she'll just sit there. She's not aground, I can wiggle her around, but the hydraulic pressure just doesn't let her go ahead. It's like sticking your finger in the end of a garden hose. The harder you push, the harder it pushes back.
I've found that after running full ahead for a few minutes without going anywhere, if I just go all stop and allow the water to rush back in behind me, It'll help me surf through sometimes. Just like your lock flush. No friction burns though! lol.
