And when technically and financially possible the canals can get reworked so the size categories can be increased (e.g. the Panama canal's new locks leading to the neopanamax category), or so ships can travel both ways ("new suez canal"). Not unlike english house sizes, ship sizes are not randomly distributed and will be kept below the relevant category as much as possible.

We need a smaller boat

Hey, Shipping Analyst here The "finger trap" was spot on and something not mentioned in the Stirling Salvage lecture with Flexport. One extra thing of note: If you look at the bathymetric maps you can see that only the eastern half of the canal is deep enough to support cargo ship operations, the other half of the canal is for tenders and smaller vehicles. So the suction effect was very pronounced because the actual useable canal volume was much smaller. Overall 10/10, very simple and gets down to the heart of the issue. I'm glad to see people are paying attention to maritime infrastructure, despite the fact that it has a huge impact on our lives most people don't know all that much about it. Stuff like the container crunch and everything else influencing global shipping sorta goes unnoticed usually.

A massive block of ship is pushing water ahead causing a reduction in UKC or under keel clearance with water rushing past causes Squat Effect.. and the only way to counteract this is if by slowing down the speed.. that't if you have enough time. With Squat effect if it sets in no amount of counter helm will make a bit of difference. This is a very real thing.. speaking from experience and after 45 years at sea.

As a deck officer who works on these kinds of ships, thank you for explaining bank suction/cushion so intuitively and simply! It would be great if in the future you covered these forces, the forces between two ships passing in a narrow channel (look up playing Texas Chicken in the Houston Ship Channel ;) or bulbous bows like you said. Thanks Grady!

Sean, this is a very well known effect and has been for many years. Check out the Titanic New York innocent in Southampton. Similar effect.

Thank you for your brilliant explanation. You are a brilliant communicator! I'm often the one person that is thrilled by such detailed technical information, within a crowd of voices shouting "who cares, it's fixed." I'm thrilled to have the opportunity to hear your channel. I just subscribed. Thank you for sharing your brain.

Cargo ships and cruise ships also require a trained helms(wo)man to navigate on the St-Lawrance river. When I was working security at the port, I would sometimes catch radio communication between the port authorities and the ship as they made a pilot swap, or warned each other about work being done.

I'm no engineer or related to science studies but I'm a huge fan of this channel. Got to learn so much, literally answers a lot questions that my curious mind has. Thank you for making this videos. ❤

Wow. The Suez Canal is like a single track railroad with passing sidings, passing trains on schedule without stopping.

This is probably the best video I have seen from someone not in the industry. They are usually hopelessly clueless about the practices, responsibilities regarding pilots, engineering side or make some wild unfounded claim regards to why the ship got stuck. This was factual, to the point and without errors. Bravo.

The sizes and tonnages of these monsters defy imagination. The heaviest ships like the Ever Given weigh 400,000 metric tons or even more. That's 4 times the tonnage of the USS Nimitz class aircraft carriers. There were a couple of 70m yachts around, and even them were dwarves compared to monsters of the seas, the biggest yacht being around 1,100 metric ton.

Top notch explanation on the topic. I thoroughly enjoy your calm demeanor and science packed discussions.

Lies - if you want to really know why that ship crashed and what the cargo was, search for it on bitchute dot com.

My Uncle (Mack) was reported to have been the pilot for the first ship, a U S destroyer, to pass through the canal after its reopening long after the 67 war. Ships were at anchor all along the canal.

Finally a breakdown that actually made sense! Thanks for taking the time to make this video. Much appreciated!

Grady, this was wicked cool and extremely informative. You have a knack for making the complicated understandable. Thanks.

As someone who has zero knowledge of engineering, and not a whole lot more interest in it, I thank you - and commend you - for such a clear and understandable explanation of what happened.

Really liking the engineering perspective on select news coverage. Your clear way of presentation and eloquence of speech make the whole production an enjoyable experience.

When you mentioned geo technical, reminds me when someone said soils engineering is a combination of art and science. Getting a PE in civil engineering and doing CE work is one thing. But soils engineering is a whole level up. We've all seen unknown blunders that occurred when everything was "done right" but a year later after a new road is built, the surface becomes like a rollercoaster ride.
