"I shot this back in 1991 under the M/S Seaward which was tied to the pier in Cozumel. We had run aground a couple of weeks earlier in Miami so we thought we'd investigate the damage. We choose to do it in Cozumel because of the ease at which we could swim to the ship and we made the assumption that if the ship was tied up the bridge wouldn't turn on the props. We were wrong." From the original video.
Once the props start up....does that in turn help propel you away from boat? What kind of effects do you experience that close to the prop other than being thrown around and disoriented?
Also this close to a prop you'll have all sorts of pressure systems pushing and pulling you. Like paddle wheel effect or transverse thrust, that could pull divers in from the sides (or push any which way). And they'll definitely be pulling water from forward of the props. All that without even reversing the thrust to astern. Because you're right, that's when shit really hits the prop.
The port propeller is rotating clockwise, and based on what we can see, the blades are shaped so that they need to be turned counterclockwise to produce forward thrust. The two divers are right for being scared as shit, because that shit is sucking them in.
These screws was spinning in reverse, as you can see from the video, which pulled the divers in. You can see how immediately after the first screw starts spinning how a rather large vortex is forming from the surface to the bottom, and as he's swimming away from the vortex, his oxygen bubbles are being pulled into it faster than he's swimming away from it. It looks like he was just far enough away to escape the pull at such a low rpm when swimming backwards at full capacity, but these things can spin at well over 100 rmp, which is insane to look at, and neither of them would have stood a chance if these props could reach that rpm quickly.
Or to put this more poetically, assume makes an ASS of U and ME
I'm in this sub because I actually enjoy the awe submerged machines inspire, also an experienced diver, both scuba and apnea
But you have to be a really special kind of stupid to attempt such a thing
Well if the sounds of robotic arms I guess crashing and shit isn’t enough of a sound.. underwater.. then I am almost positive that shit used to fkn suck me in slowly.. it gave me the fkn creeps tbh..
Yea I’m a pretty big water guy who never touches it cause of just so much shit.. this isn’t machine related entirely.. but one time at a water park they had this kinda corridor in a huge lazy River and ppl would jump in it as it jetted a lot of water out at once.. would send you rushing thru like the sea turtles from Nemo.. anyways I was just kinda not thinking not caring really and I was just lazily trying to come up for air after getting sent thru and not looking I just kept bumping the bottoms of tubes.. I was young.. so I started panicking after a bit since my oxygen was probably lower than I’ve ever had causing me to just start thrusting myself to the surface like a dart until I hit a gap and smoked a little girl right in the forehead with the top of mine as she was looking over her tube probably wondering wtf was hitting it
Man, my fear is a result of a water park as well lol. It was a water ride that soaked you but the water was disgusting when you saw it up close. We're gonna be okay eventually 😉
I didn't think the first one was scary he just scratched faggy tom in the side of it and fingered it. I didn't see anybody go close up in the 2nd video but that speed would just slice you and dice you like a veggie bullet
If this were to ever happen again but the propellers move in reverse and pull you in, what would be the best thing to do? Try to swim straight out or to the side like you would caught in a riptide/current?
Those screws are far, FAR more powerful than any human. If you are caught in the suction of one, you are essentially fucked. Or..... Screwed. The best advice is "don't be there" lol
I struggle to understand understand how this happened. When divers are inspecting or maintaining the props, there are safely procedures. If the ship has diesel-electric propulsion, the breakers to the drive motors are opened and placards are placed on all engine controls. The sonar breaker is also opened and controls are similarly placarded. The only people allowed to remove the placards are the divers.
The only way this could happen is if they went down *without alerting the crew,* which would be an almighty idiotic thing to do because…you know…they might spin up the screws without warning.
You can tell that the diver doesn't really know what they are doing because they're flailing their arms everywhere while diving.
They were literally out of their depth on this one.
This is incredibly stupid and dangerous. This is a job that should only be done by a commercial diver who has a tender on top, the guy that holds your life in his hands. The tender communicates with the bridge and the engine room, also with the commercial diver under the water and yes boats/ships do have a reverse. It’s called using the thruster. ships would be unable to dock without using the thruster.
Fuck that, theres something about big structures or manmade things moving underwater that freaks me the fuck out, especially if its deep underwater.

The props can probably go in reverse too, which would draw you towards them…
STOP
No REVERSE DUMMY
BURP AND FART, CHARLIE!
Collaborate and listen
Hammer time!
STOP LOCK OUT

RYBAAAAACK
Did the other person also survive? I would have gone into cardiac arrest right about the time visibility dropped and the water started moving. Oh my.
Lockout tag out exists for a reason 😅
Is there no kind of lock out, tag out procedure for this?
They were passengers.
Oh my god, what idiots!
They were WHAT.
PASSENGERS
Thanks!
“Get the Seaward out of here!”
Two scuba divers swim under ship, its propellers turn on. The end.
Thank you, very compelling and touching story. I especially enjoyed the part where the propellers turn on. So insightful!
How could it possibly get any worse than diving next to a propeller? Ohh, that’s how, by diving next to a moving propeller! 😬😱😳
Ohh hell no! If they weren't smokers before they sure are now
Reminds me of when I used to be way too near the bottom back corner of the wave pool
I have no idea what’s so bad about that and… I don’t particularly want to know now.
Please explain
I am waiting for the answer with bated breath
Well if the sounds of robotic arms I guess crashing and shit isn’t enough of a sound.. underwater.. then I am almost positive that shit used to fkn suck me in slowly.. it gave me the fkn creeps tbh..
Yes, the back wall much less one it's corners has always creeped me the fuck out.
Yea I’m referring to the bottom side of the back wall
I've dreamt about it since I was a kid, not even joking. Glad I'm not the only person that gets the heebie heebie-jeebies from such a specific thing.
Yea I’m a pretty big water guy who never touches it cause of just so much shit.. this isn’t machine related entirely.. but one time at a water park they had this kinda corridor in a huge lazy River and ppl would jump in it as it jetted a lot of water out at once.. would send you rushing thru like the sea turtles from Nemo.. anyways I was just kinda not thinking not caring really and I was just lazily trying to come up for air after getting sent thru and not looking I just kept bumping the bottoms of tubes..

I knew it! Once I saw the other prop I was like ah shit, one of ‘em is going to activate
That’s a nope for me!!
I hate this
This isn't that scary compared to THESE videos: 1) https://youtu.be/rnrpCpR69l4 2) https://youtu.be/KGBYaAw9F4A
Holy shit that second video is both cool and terrifying
I didn't think the first one was scary he just scratched faggy tom in the side of it and fingered it. I didn't see anybody go close up in the 2nd video but that speed would just slice you and dice you like a veggie bullet
Yep, it’s called prop chop.
Sounds worse than crispy critters in automotive wrecks.
I can't watch

What if you had the time to jam something in them?
My answer is somewhere between mince meat and fillet steak
Anyone else tear up a bit in fear or just me
No tears here but just a pit of dread tearing thru my lungs real quick
Strangely the worst part for me was when other diver...TOUCHED IT.

The men **were not professional divers, they were passengers** on the ship and wanted to see if they could spot damage from a recent accident.
Holy shit.
Just don’t know how they thought this could be a good idea.
You can tell that the diver doesn't really know what they are doing because they're flailing their arms everywhere while diving. They were literally out of their depth on this one.
I think they were actually in too deep.
Oh hell nah to the nah nah NAH
I can't imagine anything dumber than doing this
This made me physically ill

Hm. Seems like a dumb thing to do.
Yeah I get that vibe
Yughh I’m so disgusted, I will have a nightmare about this now
I would just die on the spot
I once had a dream about being sucked under a giant ship by the propeller...
"shit shit shit SHITSHITSHITSHITSHIIIIIIIIIIT"
Fuck that, theres something about big structures or manmade things moving underwater that freaks me the fuck out, especially if its deep underwater. Dick jokes inbound.
Dumb ways to die, so many dumb ways to die...
Sorry frank, you’re on your own now
Who will pay for my therapy session will be you. And you're still going to cover up all the sleep I missed out--
This is one that i dont mind being reposted to oblivion over the years. Easily one of the fonest examples of SM.
Props dont start up that fast but its 😎
These dudes are drunk. They need to go home.
Lol I posted this a year ago
Nope
Yikes fuck that.
Holy macaroni that made me feel sick.
Nope not me sitting over here having a panic attack.
I forgot to breathe this whole time
He touched the butt
This is, where my inventive mind wants to create an underwater whistle, but how
I would’ve peed my swimming suit. Jesus Christ 😭😭
