"She's made of iron, sir. I assure you, she can sink." - Victor Garber as Thomas Andrews in "Titanic" (1997).

So, English is not my first language, I never understood why you say "she" when talking about ships (?) Like, is there a specific reason or is it just way to say?

@@anttibjorklund1869 Man it would have been bad ass if he remembered to pull the line from the film... Still, he handled it well for an engineer being put on the spot.

@@C.Fecteau-AU-MJ13 I'm not disagreeing there 😄

It's not exactly a trick, just like a bad karma - calling ships "unsinkable" or "unstoppable" tends to end up badly both for ships and their crew. If I would build a ship, I would specifically call it "barely floating" so crew won't get too confident in their ship.

Loose fingers work just as good, sometimes. My mom found some naughty drawings and pictures I did during my high school years and she almost sank my ship.

Just after the US joined in WW2 it wasn't loose lips but that is what the military blamed. The real story is that the lights were left on at night in places like New York. A german U boat could sit out in the water and see all that was going on with the ships about to set off nicely backlit.

that is cause the lips do not do damage to the ship. they enable something else to do the damage and those things were listed sufficiently well.

Ya mum

​@kensmith5694 Congressman Andrew J. May is a perfect example of loose lips

You have no clue of Physics. If you punch a hole In a wooden ship hull, it sinks. Hundreds of thousands of wooden ships from ancient Greeks and Egyptians until today. Natural buoyancy is a 5 year old kid "explanation".

This was the case with an aluminum rowboat my dad had when I was a kid: he tried to sink it, just to see if he could, but there were big chunks of styrofoam under the seats that kept it afloat.

Yeah that works until the wood becomes waterlogged.

Using the water as ballast.

Even wooden ships sank, of course because they had a ballast of rocks.

It can also happen from an unplanned positioning orientation of the vessel

Spoken like a true engineer!!

Not the only possibility. Hull could remain intact but get smushed.

Please tell us more. I knew of a U.S submariner who told me his Ohio class SSBN, an 18,000 ton boat, rocked like a swing even while at 400 feet depth during a storm like you described.

TELL TELL! C’mon, we’re all ship nerds here.

Ok. You asked for it, and I promise it’s 100% true. Well after that third night, the swells and wind had subsided a great deal, and the Captain wanted to try flying. Mind you the sea was still quite rough and it was drizzling rain, but we could manage to walk on the flight deck with a good deal of caution. So around noon the brass decided to try and launch 3 planes. One Phantom, one A6 E, and one TomCat. We got the pilots and crew up on deck, but they weren’t too keen on the idea, but we were close enough for them to land in Italy at our Airbase at Aviano if they couldn’t make it back on board. I was a flight deck PO in charge of V1 ( bow director) so I had to be out there. Keep in mind all of those on that deck including the pilots crew and the Air Boss didn’t think this a great idea. We got the birds started, untied them from the deck ( making ready to throw the chains in at a moments notice and taxied them in position to load the Port side bow cat, and tied them back down on the deck. The captain gave the order to turn the ship windward to make ready for launch. And as the ship began its starboard turn into the wind, the deck began to rise ( as we were riding up in a huge swell) and continued to list harder than I’ve ever experienced before or since. The planes were actually vibrating against the chains, and the TomCat I was holding and directly now above me was tight against its chains to the deck, and the pilots were reading to punch out! It was about that time I saw the flight deck Crain ( a huge machine that stayed parked in front of the island structure broke free from its chains and was rolling towards us, while the air boss was screaming in my headset for navigation to turn hard to right the ship. I was literally holding 2 pad eyes on the deck ( chain attachment points) yet seemed to be standing vertical, and slowly the ship began to right itself and settled back to a somewhat even deck. I swear I thought we were going to capsize that thing! Our Air-boss ordered to secure the planes right where they were, get the crews out and off the deck NOW! Within 10 minutes, I learned that we had over 200 injured below decks when cabinets and other heavy items broke free and slid out of position and many thrown across the space they were in. And that big Crain that broke loose? It rolled about midship before the deck leveled back out. In 3 days we made it back to Italy, and there was no mention of flight ops again until those 2 weeks in port were complete. The fear level for all on board was maxed out during those days, I think we were all just thankful to have survived the ordeal. I went to our Division reunion in Pensacola Florida a few years ago, and brought this up within the group by the fireside one night. And I can tell you that there wasn’t a one of those guys who didn’t forget that incident in great detail back in 1979. In fact a couple of the guys said they had suffered nightmares from it.

@@mikehenson819 Wow! Thank you for the great true story! I have so much respect and admiration for our military personnel.

Ditto, thx for story, and service. B-but WHY did captain want to launch planes?? Wish I could buy you a beverage for that tale.

Don't forget the USS Maine in Havana and that one was likely just due to bad ship design.

@@flyingmonkeydeathsquadronc968 And IJN Mutsu.

Paddling a kayak in whitewater rivers, white foamy water is a lot of air and your paddle blade gets little grip in it. Most places there's solid moving water underneath to get a grip on. You look for holes -a lot of turbulence & foam - and surf it although yeah, some big holes can swallow you.

Top heavy. Blown over when one of the crew members cut one.

@@lesliecarr312 well it was top heavy, and it was almost too heavy in general; but the issue was the wind catching the sails at an angle (as tends to happen when you try to get a sailship moving) and the list allowed water to flood in through open gunports on the lower gun deck, which sat right above the waterline in calm seas. Sank before even getting out of the harbor.

I, too, love our friend Mike Brady from Oceanliner Designs

Thank you!

I see what ya did there 😂😂😂

I am amazed by your wisdom.

That's how grounding works

You need gravity too

Damn, I thought we were friends, Mike Brady from Oceanliner Designs. Just @ me next time.

He's (Mike) getting wise to us I see

Because they don't weight the same as a duck.

Dammit. I was JUST about to do it.

I would actually love to know the answer to this. Normally, I would go looking, but I'm under the weather, and I know there's no way it would compute for me. I'll say this, while these current monster sized cruise ships are fascinating in pretty much all that they do, to me, they're also terrifying. I remember seeing 3 pictures of whatever the current largest cruise ship was, like, a year ago. They were all pictures taken at night, and, She was admittedly lit up brilliantly. Just every color of the rainbow. But I swear, zero histrionics here, I was legitimately repulsed by it. As in, I could not look at it without feeling both anxiety and, weirdly, nausea. All I could think was that thing has 9,000+ people on it. Imagine how long the lifeboat process would take. No, thank you. And to be clear, no shade to anyone that likes said kind of travel. It just freaks me out a bit.

@@grayhatjen5924 I agree-imagine a cruise in a cheesy shopping mall . No comparison with the old liners

There 2, 500 people on Titanic.

​@@gordonayres2609 Exactly. I mean, from a business sense I get it. They're trying to provide enjoyment for every type of passenger. The more passenger types you can accommodate, the more bookings you'll have, the more cash you'll net by the end, yadda yadda yadda. But there has got to be a limit. Vegas has limits and it's not floating in the middle of the ocean. Which takes us right back to what happens in the event of an emergency?

@@gagalover2k10 I think OP is referring to Titanic's potential capacity. Passenger accommodations totaled 2,511 or something like that. Then you'd need close to 1,000, give or take, to cover the crew in total (whether White Star Line, Marconi, what-have-you). Those are hypothetical numbers, assuming the ship hadn't sank Her first time out. Best place to get numbers like that would be the inquiry testimonies.

Sounds like medieval dunking theory. If she sinks, she a witch! 🧙‍♀️

I’m with you!

I'd love to hear that story. It's not the typical disaster story you often get when talking about ships but incredible nevertheless.

Never heard of it. Which is a good reason for Mike to make a video so that I'll learn. :D

That would be cool I’ve never heard of it

The 1913 White Hurricane left a whole lot of ships in a lot of bad, and some downright strange situations!

@@thing_under_the_stairs indeed and it was not just the Price that was flipped turtle.

A ship doesn’t a ship doesn’t sink because it Capsizes. It sinks because the capsizing lets in more water which causes her to sink. In the end it’s all about the water getting in.

I think Mike Brady should do a video on Oceanos. It would be fascinating.

Great lakes car ferries come to mind for shifting cargo.

_Sewol_ also capsized because they'd added more cabins high on her hull, shifting her center-of-gravity higher, without being properly recertified (a certification that would likely have been withheld, possibly why the owners skipped that step.)

Excessive humidity within the hull.

@@Darilon12 Yeah... damned condensation lmao

The number one rule of shipping: Keep the water on the outside. (Number two: The pointy end goes first.)

@@svgalene465 The round ships have entered the chat...😁

@@svgalene465 "Number two: The pointy end goes first." So that's what I've been doing wrong all these years...

Yes, and his answers really hold water, too.

And incompressible

Most of the ships' volume is actually filled with air. Modern ships in essence are pretty big air bubbles with tiny film of steel coating.

One of the most frightening sinkings by storm had to be the MV Derbyshire in Typhoon Orchid.

Fun fact. One ton of water weighs as much as one ton of lead.

Magic smoke is another way of saying MADE IN CHINA.

​@@lesliecarr312Nah, magic smoke is an essential ingredient in all electronics, Chinese or no. The issue is when too many angry pixies are crammed into a device. The angry pixies have a tendency to break out of the circuit and take the magic smoke with them out of spite.

Glad you enjoyed!

Oceanos

Keep in mind the bit about a burst waste water pipe is just a theory, they don't actually know what happened to cause the flooding. What they do know is that one of the hull compartments was breached and taking on water, causing the engine room to flood which eventually blew out the engines. There was a loud bang, the ship went dark and started drifting and taking on more and more water from high waves in the storm. Also, the guy who ended up coordinating much of that rescue was part of the crew, though he was a musician. A guitarist, and he relayed as much to the Coast Guard. The captain had ordered the ship abandoned but had not sent out a distress call, he also gave no clear instructions about how the evacuation was to be done; leaving junior crew and passengers to sort it out amongst themselves. It seemed he'd panicked and gone into shock, as he'd been observed just sitting at the rear of the ship, in the dark, chain-smoking. Didn't really do much until the rescue helicopters came the next morning, where he demanded to be the first one off to "coordinate the rescue". Which apparently meant sitting on shore and occasionally asking passing rescuers how things were coming along.

@@user-es4iu7ls2oYup, I was about to say that. 😂😂

​@@redshirt49 The ship shouldn't have been taking on any water from high seas - the waves would have to have been swamping the ship's decks in order to get access to the air intakes and ventilation shafts. Aside from a hull breach (extremely unlikely, as there were no reefs in the area) a failure in the ship's plumbing was almost certainly the culprit. To this degree, it has been pointed out by naval architects that the Oceanos' plumbing system did not have a backflow prevention gasket, so it would not have been able to halt incoming water, nor did it have shutoff valves at the cutouts of bulkheads, allowing the water to transfer from compartment to compartment as the ship flooded. Given eyewitness testimony about backflooding toilets and sinks before the ship lost power, it's pretty safe to conclude that's exactly what put her down. Following the sinking, the plumbing systems of ships at sea were fitted with shutoff valves at every bulkhead cutout and backflow gaskets to prevent water from outside flooding into the ship.

I don't think gravity pushes down. It sucks. Especially if you're 31,000 feet up in the air. The secret of keeping a leaking ship afloat is to pump more water out than is coming in.

Not wrong, exactly, but it's hardly ever how it gets described. Not least because you can design a ship that has no air in it that will still float.

Basically right. Air has extremely little weight, while the water's much higher weight adds to the buoyancy equation. And when the ship's total weight including the water gets too high, down goes the ship. Replace it with air again, and up comes the submarine.

Thats awesome!

Sometime, people "helping" is worse than people doing nothing.

@@Kr0noZ well to be honest this is the same personal who saw the torpedo coming and just.........stared at it. Im not sure if they had time to get out the way, but of I recall correctly that all they did.

So the crew turned the ship into a thermobaric bomb?

@@user-xu2pi6vx7o pretty much

As memory serves, it was more that _Taiho's_ complement had put out the initial fires, and then turned on the blowers to clear the fumes. Extremely combustible fumes. With extremely combustible results.

Dona Paz. Spanish for "DO NOT PASS". Roll your dice and take your chances. And take theirs while you're at it.

ABSOLUETLY...this happens with car ferries all too often. The cars aren't secure (Parking brake is not enough if the ship starts rocking). and they start rolling.

Hard to prove that it happened because a) it would happen so quickly that there would no time for the crew to get off a mayday b) unlikely to be any survivors or witnesses, they would also sink, and c) the wreck may show no underwater damage, but absolutely no indication of what had sunk it, which could also be explained by other causes.

There has been speculation that enormous bursts of methane from the ocean floor may have been what caused mysterious disappearances of ships and planes in the Bermuda Triangle. Methane vents and crystals have been documented in such places.

Yes - someone also in the comments here refers to a fishing vessel in the North Sea that it is believed was sunk this way.

it wouldnt happen, it would have to lower the density of water significantly over a very large area and volume.

Then why do wooden ships sink?

​@@patparkhurst9689Cargo and ballast. Ships that are too buoyant don't sail well, so they would fill a lower section with rocks as ballast to get an optimal buoyancy. And even when ballast isn't required, the cargo often is heavy and dense enough to sink a water filled ship. Ships that can't sink are called "neutrally buoyant" and you often see that with lifeboats and small tour boats like the newer replacements to duck boats.

@@patparkhurst9689 because of all the other items on board that are not made of wood, I'd think.

When it starts pooling on the floor you’ve had it.

Thank you!
