Why can some ships stop immediately?

Define ship, in this case.
To stop a 300 meter tanker takes more or less work depending upon what's in its holds. I don't think a full tanker can stop in less than a mile.

It is my understanding that commercial ship's are required to be able to stop within 15 times their length.

when they hit an immovable object and break up?

Reverse jet bucket shot? Or POD drives ?

This design should be able to stop quickly!
Docking port side like a champ.

It costs extra so not every ship can use the Hyde Ship Brakes.

They don't

Thanks for your response!

I think this ability is quite important. It might be more applicable to small boats.

I need to carefully study the technology you mentioned. Thank you!

I don't know how fast a reverse-pitch reaction can be without damaging the propeller. It probably depends on the propeller's scale and the type of reversing mechanism.

Nothing stops immediately. In theory, a theoretically rigid body could impact another theoretically rigid object of infinite mass and stop immediately. In the physical world there is always a delay.

What I saw was that a submarine model could come to a stop. I'm also now questioning whether this video was generated by AI.

Everything can come to a stop. It takes different lengths of time though.

Found from Google and Gemini:

Here's a video on some techniques for stopping a ship.

It discusses high frequency rudder cycling and low frequency rudder cycling; about 5 to 7 ship lengths.

Crash stopping on two anchors usually rips the winlass out of the deck, but 1.5 ship lengths.
