This is actually my first time seeing a cruise ship this big on a beach shore tbh

We used to belly board on the Columbia River off the container ships wakes.

I go sailing off a Dike on a beach by a major ship channel it’s always funny watching people scramble after a container ship goes by

Could someone explain because the ship appears to be displacing a bunch of water (which makes it float) so wouldn’t the water be pushed out while it is nearby, and then recede when it departs?

I’ve been on that ship, and yes, it does displace a huge amount of water I a smaller port!

I’m no cruise ship expert but isn’t that absurdly close to shore?
Oh wait nevermind

This is exactly how tsunamis kill a lot of people.
“Look, the water went away. I’m walking out to look!”
then WOOSH

Imagine the captain “I’m just going to casually pilot this 23 story tall, 111 story long floating seascraper between the sandbar and the beach”

This is why we don’t want cruise ships in Venice -.-

Not much harmony with the sea

Explanation:
This is Bernoulli’s principle in action. As the ship moves through the narrow gap between its hull and the shallow bottom/shore, water is forced to squeeze through a restricted space and speeds up. Faster-moving water has lower pressure — and lower pressure pulls the surface down, creating a depression rather than a wave.
This effect is actually stronger at slow speeds. A fast ship would push a dominant bow wave, but at typical canal speeds the suction effect takes over. The shallower the water and the closer the shore, the more constricted the flow, and the more pronounced the drawdown.
It’s a well-documented phenomenon in maritime navigation — it contributes to what’s called squat, where the ship itself sinks slightly lower due to the same pressure drop under its hull. Moored boats nearby get pulled toward the passing vessel for the same reason, and water at a low dock will visibly recede before the ship has even passed.

I don’t see the attraction in cruises.

It’s crazy how those kids can darn near walk up to the thing.

Bernoulli’s principle. The ship is moving through the water, the ship’s side is curved like a wing, the water is forced to go around the ship, the beach and side of the ship create a narrow neck for the water to go through, the water moves faster past the ship’s sides than at its front or back, fast fluid is at lower pressure if it conserve energy due to Bernoulli’s principle, low pressure water is pushed aside by constant pressure atmosphere.

It’s honestly insane how big some ships are
A Disney cruise ships in about 3 times bigger than the titanic.
The biggest cruise ship today is about 5.5 times bigger than the titanic

It’s over a hundred feet longer than the Mauretania…….. and far more luxurious!

Saw this same effect once on the Minnesota River, relatively small river but still channelized for barge traffic. The barges would come through and displace enough water to draw the river down like ~2ft and then rush back up afterwards. Pretty cool

That’s just how these ships move. They compress space-time in front of the ship and expand space-time behind the ship, allowing it to “fall forward” and ignore the normal laws of physics. At full power it should allow the ship to travel faster than light, but we don’t have the technology there yet.

I was like that channel looks very shallow how is it enough for it to sail through… then the water returned

There’s no replacement for displacement.

You know, after December 26th, 2004, the one thing that you would think the entire world would have learned about tides is: If the water is receding on the beach, get the fuck out of there.

When will folks learn that the ocean randomly rapidly receding is always a bad thing?
