How Did She Rip Her Bottom On This Rock?

✩ABOUT THIS VIDEO✩
In this video, we investigate the effect of squat and see how it can mean that ships hit rocks deeper than their own draft. We use the example of the QE2, which struck an uncharted shoal after experiencing squat.

Imagine having the balls to floor a newly built ship under a bridge that it doesn't fit under.

[andylane]

Holy crap, just built a 1 billion $ boat, put the last touch of paint on it then drive it at full speed toward a bridge with a physicist telling you not to worry, it will sink down in the water due to Bernoulli’s principle. Thats a butt clenching moment if ever I heard of one.

[CaptainAndreas]

Being a Captain and active in the Maritime Industry for more than 20 years, all I can say is that your videos should be teaching material. Congratulations!

I lived here during that event. I LOVED the anecdotal interviews following:

Nervous passenger to the Captain, "Captain, should we abandon the ship?"
Captain, "My dear, we are already on the bottom! Go back and have another glass of Champaign!"

[GiovanniRuffinengo]

"Captain, there is a bridge ahead and we are too tall! "
"Faster goddamnit! I said FASTER"

[welbhloud]

As a seaman on a small ferry, I can see that every time we are about to land. As we slow down, the bow comes up from the water.

A tiny correction is that Oasis of the Seas didn't squat under a bridge over a river, but rather over the Great Belt strait in Denmark. She has telescoping funnels, and would have cleared the bridge by about a foot, but she barrelled at it at 23 knots, and thus gained another foot from squat. Still, 2 feet of clearance at 23 knots in a brand new ship, biggest in the world, under one of the most heavily trafficked car + train bridges in Europe, that must be a proper pucker event..

[FluppiLP]

you have no idea how happy your correct explanation of Bernoulli's principle at 2:49 made me :D
The fact that you said it occurs simultaneously and not one casues the other made me very happy indeed :D

[LocoCoyote]

I don't care what anyone may say...these videos are some of the best on YT. I always learn interesting facts and the reasons behind them. Bravo!

[sethtothemax]

Ships have ground effect. Fascinating.ships and planes have so much in common

[Grandmaster-G]

There's so much important information in this one (again), i hope every skipper cruising through a canal knows this stuff... I can picture many situations where people overreact or simply react wrong due to not knowing the physics behind what's happening... oh boy. Thanks !

[loosegoose]

As a pilot (air, not sea) these sorts of videos are incredibly interesting to see the similarities in air versus water behavior. Thank you for such great content.

[bigdmac]

Two things : The QE2 for me will always be one of the most beautiful ship designs ever created, and, this was a superb presentation.

[Runnifier]

As a sailor solo cruising on a sailboat, these videos help me navigate more intelligently and more safely. Thank you. I love your videos!

[Nintendo]

Its so cool to see Bernoulli’s principle in use here sucking a ship downward, and also seeing it used in almost the same way to suck race cars closer to the ground to get more grip with ground effects. I love this stuff!

[Openbaarmaker]

Ah, man, finally a video i can REALLY relate to! I've been working as a 1st mate on the shallow seas north of The Netherlands and we really had to work with this phenomenon. Excellent video!

[aezravito]

You can't always be too sure or careful.
It's amazing just how things can be explained.

[Tinhare]

We experience exactly the same thing on our deep drafted narrowboat. Some of the UK canals are quite shallow in places you can be flat out and only be doing half the speed. also you can see the squat as the boat noticably sits lower in the water. we also experience bank effect and have also practiced the Texas chicken, works a treat if the other boater knows about it also, most don't though.
Great explanation. I'm surprised the captain chose to go over such a shallow area when deep water was closeby.

[avramnovorra]

The more i watch these kinds of videos, the more i realize i do not know much about ships.. and i love it

[yankeexpress]

I was Mate this day on a nearby Sea-Land containership as we transited offshore from Boston to New York harbor and heard the VHF traffic on the air. Next day after we docked in Port Elizabeth NJ saw the story and interviews with passengers on TV.
