------------------ABOUT THIS VIDEO------------------
In this video, we investigate the shipping manoeuvre used in the Houston Ship Channel, the Texas Chicken.
The Texas Chicken uses the interaction forces between two vessels and the banks of the channel to allow large ships to safely pass.

"Everstuck" lmaoooooo
0:59 almost because everstuck
Lmao
Lol
Yeaa....
Evergreen
Ah yes, the No Fucks and Ever Deeper.
0:18: “they will collide and annihilate each other” I think this specific outcome only happens if you have one car and one antimatter car.
well if you have some anti matter and some regular, pro matter surely you'd just get harmless regular matter!
Lol, when he used the term "annihilate", I thought of matter and anti-matter too.
Or if they go near the speed of light
@@Welv1987 To be fair at that point the plasma that is the leading edge of the vehicle mixed with the air ahead of it will be undergoing interesting interactions well before that. That is to say you just made a fusion car which is currently fusing itself with the air of the atmosphere. Suffice to say it will no longer be a car in very short order. As for exactly how these shenanigans look is an interesting thought as towards the front of the car it will most likely be predominantly atoms from the car actually fusing much of which are Iron or heavier so it would probably be a net loss of energy there. Probably wouldn't want to be viewing it from the outside for sure though the leading edges will mostly be the atmosphere participating which would give off plenty of high energy photons and such I think you would likely be very very dead if in line of sight of that turns out X-Rays and Gamma rays are bad for ones health in high doses.

There is some reason special channel pilots are required in places like the Kiel Kanal.
'Schland!
Because we are talking about Germany here, and in Germany, you can't just take your ship and move it past another one using physics. What are you, a captain?
@@Chrischi3TutorialLPs as far as I know Pilots are mandatory in a lot of other major shipping channels from a certain size of ship upwards.
@@netsailor The Kiel canal is the only canal that I know of though that not only requires a canal pilot but also a canal helmsman for ships above a certain size (and/or under certain wind conditions). Guess that's what it takes to be the most frequented artificial waterway in the world (the Kiel canal sees about as many ships each year as Suez and Panama canal combined!).
Same here in the Houston ship canal, pilots make seriously good pay too.
I've seen this first hand as a deck cadet on a container ship. It was scary first time I saw it, but then I learned its standard procedure.
546 likes and no comments? Lemme fix that..
On large modern ships, are these maneuvers carried out autonomously by computers (accurately monitoring positions, velocities, water pressures etc), or are they still done by experienced human crews?
@@fredbloggs8072experienced human (pilot) . Witness this effect as cadet too at savannah, usa the pilot giving order to the other vsl’s pilot 😊
The same thing can happen with narrowboats in canals (this is in the UK), and this would be an extremely useful tutorial for that. It was quite a shock the first time the bow started to pull out after passing another boat, and I wasn't expecting it 😄 Thankfully the stakes are a bit lower when your boat is "only" 60 feet long and moving dead slow, it's all part of the fun really
Theres a training for captains using the narrowboats as a simulator.
Due to the power to weight ratio being largely the same, both the narrow boat and the large cargo ship can behave the same way especially on canals.
If you watch the old working boats it’s how they pass. Don’t try doing it with most leisure boaters though as they do think it’s a game of chicken.
@@Tinhare It's not about playing chicken, it's about knowing the best time to head to the side, which is certainly later than I first assumed. It's never a bad idea to have some idea of how the physics works
@@mikeflowerdew7877 That was my point.
While a typical narrow boater won't wait until the last minute to move off the centre line of the canal as per the video (which is probably for the best), the last bit of it, the 'self centering' effect as the stern's pass each other is very noticeable...
It's funny to see this video title. I lived on St. Thomas for 11 years. Used to listen to my marine radio for fun. You would hear the same argument weekly between some Russian capitan and another say Philippineo. The Russian guy would start by being stupidly rude informing the other ship to move or else. The other ship would say I have the right of way. Then usually the Russian would go full speed while cusing in Russian screaming on the radio. Eventually the coast guard would chime in and inform them both to adjust course and to shut up. This was weekly if not more often.
I dont think it's spelt Philippineo
@@zacklp3844 Sorry. A boat capitan who is from a pacific island with a funny Asian Spanish accent. My bad.
@@tireballastserviceofflorid7771 As a Philippine national with Russian friends, I certainly could imagine the whole story vividly.
I believe it by the Russians being aggressive and Filipinos being reasonable and polite. I'm actually here in the Philippines as I type lol... nicest people ever.
Hey! Shut the fuck up! - Coast guard
I never knew that this was a maneuver that ships took. The more you know I guess.
Is this done by pilots from the local authorities who know the channel, or are individual ships expected to have personnel able to do this?
yes
Whoever is on the bridge. If there were pilots, there'd have to be additional boats for each vessel.
Pilot gives orders to the bridge crew , captain is ultimately responsible and can ignore the pilots local knowledge. It's required in most narrow channels to have a pilot, especially in places as narrow as in the video. In my river, we don't do this, we check in with traffic, monitor the ais for river traffic, and communicate via vhf. We have a few wide 'basins' to wait for opposing shipping traffic so we don't meet at the narrow part of the channel.
Yeah. I grew up on the houston ship channel. What they didn’t mention is the average depth of Galveston bay is about 2m (6ft) and the ship channel is something along the lines of 10-20 m deep.
They are required to have pilots on board ands the pilots are very familiar with having to do this. My dad wasn’t a port of houston pilot but he went to school with many of them and remained friends.
I seem to remember most of the groundings were caused by mechanical malfunctions or a ship interacting with barges.
@@jellef4704 yeah pilots are required except for barges (even though they have a “pilot”). I think there’s 2 turning basins in the houston ship channel. It’s a crazy place. I think there’s a ship entering/exiting every 6 minutes. And it intersects the intercostal waterway. As a kid I loved hearing the ship traffic at that intersection
I actually expected from the title for this video to mention the Halifax explosion in 1917 where two ships in halifax tried to use the narrow channel, one leaving the port, one entering, at the same time, which lead to both playing chicken and inevitably crashing into each other. One of the ships was packed full of explosive to be shipped to France for WW1 so when the ship crashed and exploded it leveled the city.
Just a little ping to let you know (in case you didn't) that Casual Navigation recently put out an excellent video about the Halifax incident!
@@Lowkeh Just checked it out, thanks
I never knew about this careful, coordinated dance but damn it is impressive to know that everyone involved in a Texas Chicken is participating in a calculated move.. now i can look and sound clever in front of my peers in thee vent we see 2 ships pulling this off
That's a good way to put it...
Instead of Texas choreographed ballerina dancing, it's called Texas chicken instead of "coordinated super advanced and skilled canal boating"
It's the same for going under Potter heigham Bridge. You gun the engine and water pressure keeps you straight. You can't steer because the stern needs to move in the opposite direction and would hit the bridge. In a cross wind speed is essential.
I love that a considerable amount of large ship piloting basically boils down to sheer brute force like a toddler would attempt.
I remember seeing this as a kid growing up along the Ship Channel. It’s only 550 feet wide and watching these tanks go at each other was amazing. One note how ever. They do screw up occasionally. It doesn’t happen often though. The Houston Pilots are very, very good. Especially those that take ships up The Buffalo Bayou past the Lynchburg Ferry and into the area of the Turning basin. It’s twenty miles of refineries and chemical plants, with a few car carriers thrown in for good luck. The majority of the container traffic goes to one of two large container facilities that are off the Trinity Bay and not so far up the channel.
"The trick to playing chicken, Mister Ryan, is knowing when to blink."
"Everstuck"
I just spit my coffee. Thanks!
I learned this stuff at the Great Lakes maritime academy, so it was interesting seeing a video talking about these hydrodynamic forces.
Night driving on unlit 1.5 way roads (barely enough for 2 cars to pass each other) kind of works the same. There is a force pulling the cars together - natural human tendency to steer toward a reference point if no other points are visible (related to tunnelvision). So making way "the last second" works out better.
Not advising playing chicken here, that's bad ofc. But if you make room too early it can make the other driver take more road, even if he did not intend it.
driver should stare at the road line and avoid staring at headlights because they will drive toward the headlights. (On unlit road the incoming headlights from the opposite lane will appear to move further sideways as it get closer, thus creating an illusion that the car the driver is in is moving off course.)
My wife's uncle was a pilot in NY harbor. He had told me about this maneuver and also stated that it would increase the depth of the canal enough for both ships to pass each other even if either side of the channel wasn't quite deep enough for them to get out of the channel.
Mmmm... texas chicken

This reminds me that one notable winner of a prize going to the oddest published book title of the year was 'How to Avoid Huge Ships'.
This is probably puzzling to this channel's creator, for whom it would seem a perfectly sensible subject and title.
I live about as far away as you can get from the ocean on a navigable shipping river so I find this all very interesting.
How far?
@@simonshotter8960 about 1200km and the Rockie mountain stand between me and the pacific. Also at about 700m in elevation so there is alot of rivers but there all small before they flow together to make bigger rivers
@@collinscody57 you’re in the 1%. Most of us live within 150km of a coast!
I was just saying today here in the UK, it’s blazing and was nice to only be 15 mins from the sea and thought then I wouldn’t want to be that far from the coast.
Kudos to you man. At least the Rocky’s are close ish. ⛷
@@collinscody57 make your mind up you using kms or miles? I'm confused? I can use both! But pick a measurement and stick with it mate :)
? Elevation is commonly measured in meters. Distance in kms.
So fluid dynamics...was my initial guess
But learning the specifics makes sense, vehicles traveling in water behave different than those on ground than those in air, as looking at high and low pressure areas reminds me of a planes wing and how it stays in flight, except it's using that concept flipped on its side, but in a non compressible medium
(like how hydraulic brakes or buffers work vs how they don't work when there's air bubbles since air is compressible....to a point)
Awesome video!
Cool that Texas chicken doesn't end how you'd assume Texas chicken to end(with a giant car crash and a gunfight... I'm kidding to all Texans out there of course)
Texan here, you’re pretty spot on.
@@Luke55827 I forgot fireworks... Tho that's American and maybe not uniquely texan... Unless they're big awesome fireworks, and after some Texas chicken the winner gets some Tex/Mex food
Or maybe Im thinking with my stomach...
Some Texas barbecue chicken tacos....
That's my second thought when I hear Texas chicken is some good Texas BBQ with some tortillas for bread
In Aviation you have Ground Effect, so if you´re close to touchdown you will be pushed away from the ground. Same concept, as with the bank here
@@markusp9569 interesting, it never occured to me that ground effect is similar to the bank effect in ships. And ground effect is pretty strong especially for high wing aircraft
Did you die?
the animations on this channel are just so good! I am amazed every single time! keep up the fantastic work, my man!
I performed the Texas Chicken once as the OOD on USS SAN JACINTO (CG 56) while visiting Houston. While we regularly deal with some of these effects during underway replenishments, it is not something naval vessels would normally practice. We did simulator training on the maneuver prior to the visit. Briefed the maneuver during the entering and exiting Nav Briefs and discussed with the pilots in both instances. On the outbound we did encounter another vessel in the channel and had to perform the Chicken. While a little unnerving for those new to it, it obviously worked as intended.
This is hands down my favorite video yet from you. I love Houston a little more now
"...this is a lighthouse mate, your call" :D
This is the best, most informative and easiest to understand explanation of "ships go turny turny in channels" I've ever had the pleasure of receiving.
Thank you so much for the vídeo! You've earned my subscription
"Everstuck", that got me so hard! 😂🤣🤣😂
I had to pause the video due to laughing so hard 😂
WOW, didn’t know any of this, thank you for explaining this fascinating topic.🐳
Do all ships swerve to the right in such maneuver? It would be a disaster if some ships have different swerve conventions...
Ships (and aeroplanes) on a head-on collision course, both ALWAYS alter course to the right. They pass "red on red"
@@RoBert-ix6ev Thank you! 😁
Yes, boats pass 'port to port' so they always turn starboard, meaning that their port side will pass on the port side of the other ship
@@RoBert-ix6ev Aeroplanes might do, unless TCAS tells them not to. Then TCAS (having communicated (!) with the other airplane's TCAS) is to be followed. Or you go boom. en.wikipedia.org/wiki/2002_%C3%9Cberlingen_mid-air_collision
@@ChrisBigBad I think TCAS only provides vertical resolutions, so it won't tell you to turn left or right, just climb or descend.
Really neat to find out about a maneuver named for the Ship Channel I work.
Thanks for the vid, and the suggestion to see this vid.
You are my ASMR King! When I can’t sleep, I put on one of your videos and they work like magic! They are also very interesting and informative, as well, even though I have no connection to shipping or navigation whatsoever.
I kind of had an idea of what was going on from the thumbnail, but the explanation helped put things into perspective! Great video!
Really interesting, I have not heard of this but it makes perfect sense. Be great to see drone footage of this actually happening.
"You play chicken long enough... you fry"

Wow that is really amazing ! I had no idea ! Great video. Very interesting.
Does it make a significant difference if one ship is particularly longer than the other?
In that case the vessel is likely smaller across all dimensions, and thus it may be possible for the larger ship to travel much closer to the middle since less of a gap is needed for the smaller ship (which experiences less bank effect due to its size)
yeah the longer one gets stuck while turning a bend and runs aground
i would assume, the longer one stays closer to the middle(but still swerves), and is going an bit slower then the smaller one. this is just an guess.
On the French canals ,we frequently encountered commercial bargesin narrow canals . These were at least 280 ton to our 20. We would be pushed by the current all over the place . We never bumped but it was more by luck than judgement. The worst bit was just as we were nearly clear and we were sucked out from near the bank.. Exactly as described in this excellent vid.
This has to be one of the most stressful maneuvers to attempt
If it’s stressful don’t do it.
Me, a Houstonian seeing CasNav talk about our ship channel. "YEEHAAWWW!!!"
You just answered a question I've had since I was younger and saw it in person. Thanks
Super cool breakdown of the physics involved... I love learning how and why things happen, the whole world just working everyday is a combination of miracles on a global level!!!
Cool, learned something new. There is a similar effect when boats are alongside each other. I think this channel has covered this. Thanks. I'll watch to see if this is used in the shipping channel I sail out of.
I loved learning about this, thank you!
When I was a kid I went paddleboarding and got sucked into a little spot between two piers. I think I just found out why.
No, that will have been water currents around the piers. Bank effect is only significant when a vessel is close to the bank relative to the size of the vessel itself. To get bank effect on something as small as a paddleboard, you'd have to be within a few centimetres of the bank and, on something as small and slow as that, the effect would be so small that it would have almost no effect.
@@beeble2003 Awesome, thx
Everytime I watch your content, I’m flooded with new knowledge
Great video! So interesting!
I just found your channel. Superbly made content. I would love you to do longer documentaries too!
I wish you hadnt found his channel because us long term watchers love short form content
This world is rapidly passing away and I hope that you repent and take time to change before all out disaster occurs! Belief in messiah alone is not enough to grant you salvation - Matthew 7:21-23, John 3:3, John 3:36 (ESV is the best translation for John 3:36) if you believed in Messiah you would be following His commands as best as you could. If you are not a follower of Messiah I would highly recommend becoming one. Call on the name of Jesus and pray for Him to intervene in your life - Revelation 3:20.
Contemplate how the Roman Empire fulfilled the role of the beast from the sea in Revelation 13 over the course of 1260+ years. Revelation 17 confirms that the beast is in fact Rome. From this we can conclude that A) Jesus is the Son of God and can predict the future or make it happen, B) The world leaders/nations/governments etc have been conspiring together for the last 3000+ years going back to Babylon and before, C) History as we know it is fake. You don't really need to speculate once you start a relationship with God.
Can't get a response from God? Fasting can help increase your perception and prayer can help initiate events. God will ignore you if your prayer does not align with His purpose (James 4:3) or if you are approaching Him when "unclean" (Isaiah 1:15, Isaiah 59:2, Micah 3:4). Stop eating food sacrificed to idols (McDonald's, Wendy's etc) stop glorifying yourself on social media or making other images of yourself (Second Commandment), stop gossiping about other people, stop watching obscene content etc. Have a blessed day!
This is really nicely explained. Brilliant video.
Learn sometime new every day, thanks for the informative video
My father told me about this maneuver decades ago. He retired in 1970 so at least 52 years ago. This maneuver was done in the Welland Canal.
LMAO "Everstuck" You made me laugh IRL
Really enjoyed this video and all others
Great video! We experience this in the Newcastle AU when the river is in fresh water conditions. The passing ship can pull a vessel away from the berth.
Just awesome info, physics are really the star in the navigation profession. Awesome video 👌
This I did not know. Thank you for teaching us something quite interesting.
This is something really interesting to learn.
Wonderful! Thanks for the good explanation and the everstuck!
Good Stuff,Great Tips😃👍🏿
Fascinating stuff!
Great Video! Thank you
Great post my friend.
This is so amazing wow! Learned something new!
I love this, it’s based in scientific understanding of forces, and cooperation being the best strategy
The Texas chicken and this video 10/10
I fly airplanes in Houston and have seen this many times. Its an incredible view to see Texas Chicken in real-life.
Very interesting ! I would have never known
The "Everstuck" made my laugh out loud lol
Every time I watch a Casual Navigation video I end up binge watching the topic of the video in the real world, so I’ll be off looking up Texas Chicken for 20 minutes 👋
i learned something new today! never knew this happens with ships. cool stuff!

This is amazing!
This is so fascinating
I wish you uploaded more, I’ve binged all these videos, they are relaxing for me
Why do MASSIVE ships play Chicken?
Me: “It’s NOT what you think”
His mother and father were pixelated. I'm glad he's overcome the odds
I had no idea that boats made those little plusses and minuses in the water like that. Kool!
remarkable, fascinating and beautiful.....great video!
I do not live anywhere near salt water but I love this channel.
Crazy you mention this because I noticed a small wake wave about 8-10 feet in front of the boat as I navigate. Never made sense to me.
I don't even like the ocean in person and I'm here learning about bank effect at midnight on a Saturday. How did I get here? No one will ever know, but I can't leave now!
It's really cool to me that even though we're talking about ships and water, we still see Bernoullis principle in action!
Well there's my 'learn something new every day' day for today. I suppose I might've worked it out for myself if I'd ever even known ships did that... Which I didn't. Then again I might not 😄
I'm so impressed I subscribed even though I have only a passing interest in ships and have been known to get sea-sick on the Isle of Wight ferry.
Imagine it's your fist time to do this manouver and the other ship is closing in. Gives "working under pressure" a whole new meaning.
Id say both of the ships have bragging rights after this, maneuvering a massive ship like these is not easy. Let alone with all these changing outside forces trying to crash the ship. Hat's off to the hardworking crews that make modern life possible.
that was surprisingly interesting
thank you for the video
I've heard about this before, but it's SO cool! And SO Texas.
EDIT: "Everstuck"... LOL!
Hey there, I was wondering why there is no video of sailing speed and techniques. Maybe an idea for a future video ;) ?
Wow. Very interesting
while i might not sail a ship myself i find all this stuff interesting
Great video! Since we're discussing vessel vessel interactions, how about a video explaining underway replenishment?
It is amazing that this works.
From a game with potential winners and losers, to a dance where everybody is happy!
Life is better on the water!
My cousin's husband worked on an oil rig, the amount of near misses at night at this Chilean one by boats without lights on was terrifying. Usually the night work is indoors.
We do the same thing on oilfield roads that are generally 1.5 trucks wide you drive straight towards the other guy and then pull off within a reasonable distance and then go back to the middle of the road. If you’re bigger then you stay centre or smaller you pull off. Size matters 🤣
Can you explain Sheer line. I always learn new things on your channel keep on making more video. Thank you
this is dangerously fun
I live on clear lake right on Galveston bay I see that happen all the time sailing, or even from shore. It's most on the icw
"Everstuck" Too good xD
I cant believe you made a "chicken chart" 🤣
I know nothing about boats, I'm a physics student and I love listening to passionate discussions of classical mechanics
I know not every invention is an accident, but I like to think that the captains who discovered this technique both wanted to win the bragging rights and didn’t swerve their ships until the very last minute in the Houston Ship Channel. Both captains stared at each other as they barely got through. Then the ships went on with their own paths with their captains wondering how their ships were still in one piece and without a scratch. They told their tale to other captains and soon many adopted this technique. And before you know it, it’s now a professional manoeuvre called the “Texas Chicken”
Interesting video
