looks nothing like titanic + i can see you know ships only because of titanic

It's really best to shut off steam first, but with a smaller engine it's less of a jolt than with the 4-story tall monsters in the Titanic, so you can get away with it. In this context it's what's called a "crash stop" so you need to reverse as quickly as possible.

@@Shipwright1918 Wow okay, makes sense now. Thank you for replying and answering my question that I’ve had in the back of my head for ages now. :)

@@ryantimm9748 Crash stops were possible on the Olympic Class liners but were only done in an absolute emergency since that’s a lot of wear on your engines and running gear. It also puts wear on the propellers since suddenly going from full ahead to full astern causes a lot of water cavitation around the props which translates to a lot of vibration. Olympic apparently performed a crash stop during the incident where she accidentally rammed and sank the Nantucket light ship. Titanic performed a crash stop test during her sea trials and I assume the other two Olympic Class liners did the same. It’s also worth noting that when Titanic was leaving Southampton, her wake broke the moorings of the liner SS New York. Captain Smith had the engines on Titanic quickly thrown into reverse to prevent the New York from being sucked into Titanic’s side, narrowly avoiding an early end to the voyage. I assume that would have been done as a crash stop type maneuver.
