Could you imagine 11 days of that.....what a risky move....one slip and you float away and die in the middle of the ocean....how do you sleep?

What a nightmare

Yeah, youre not floating away if you fall off the rudder of a ship under way. You're getting drawn into the props and chopped up into fine fish food.

Lol no, the rudder is behind the prop, which propels the ship with enormous force. That force would thrust you much further away from the prop and the ship in general, likely tossing you about like a rag doll for a good while. There may be circulating back currents, but I doubt they’d be strong enough to overcome the thrust of the prop. There are few engines on the planet more powerful than these.

Your for sure drown in the prop wash, right? All that massive turbulent water half mixed with air wouldn’t be something even the best swimmer could stay afloat in I’d imagine.

Actually it's not as bad as you'd think... Turbulence in a situation like that a trivial factor, the tendency is to either stay in the flow (where your relative velocity is low) or get kicked out of it. Unless you're trying you're pretty much guaranteed not to stay at the interface of the prop wash.

And aeration from a point source like that is very much a function of water velocity, and the air bubbles tend to rise pretty quickly. So if you look behind a motor boat you might see a long trail of bubbles but the length is mostly because they get pushed far out, not that they take a long time to rise

With a pfd, if you had the foresight to hold your breath, I'd say it's pretty much a guarantee that you'd survive. So in context is just a question of whether they got caught off guard and got unlucky with their breath, or of they got disoriented.

I see. Thanks for the well thought out response! Think I’ll still steer clear of rudder sitting though. :)

Would think individual would float as past the props and ship moving forward. Not sure on fluid dynamics of props and if they suck water from behind them but would think that would be inefficient and engineers would have found a better design.

Im wondering if they had a bag of supplies. Mainly water because I can't imagine lasting in that condition for long without any

MerryGoWrong t1_iy7zccv wrote

They would have had to, there's no way they could survive that long without water.

As a rough rule of thumb, a human needs about 1 liter a day at an absolute minimum, assuming you aren't sweating or exerting yourself. That just replaces what you lose through normal metabolic processes.

You could probably do with even less temporarily, but at that point you're just delaying your death because you're still experiencing a net loss of water.

An average human undertaking average activity levels needs 3-4 liters a day to stay healthy, not just alive.

And how long can you go without sleep?

neryen t1_iy8hr6q wrote

The longest recorded time is 11 days, however there is no known fatal limit.

We become severely impaired and begin microsleeping after 48 hours.

They could take turns sleeping while the others keep them safe. 4 hours of sleep, 8 hours awake to watch your buddy. Not saying it would be a very comfortable sleep, but they obviously survived (some how)!

i don't think i drink a litre of water each day... what happens if you don't?

Sometimes_Stutters t1_iy7z8nu wrote

That’s a tough call honestly. The cold and lack of oxygen would be a serious issue, but you only need to last a couple hours. I think I’d take my chances on landing gear before 11 days on a rudder.

You 100% die there.

Sometimes_Stutters t1_iy80ohs wrote

I had to look it up, and it appears there’s about a 25% estimated survival rate (though not entirely verified).

> Counting the California teen, 25 made it alive, for a survival rate of about 1 in 4. The FAA notes that the rate may be lower, because people could have stowed away and fallen out of the wheel well without anyone knowing.

So the 25% is more of a ceiling though how much so is unknown.

With the most high end, Mount Everest quality gear, supplemental oxygen, and having a fairly upbeat attitude during your 10 hours of pure hell, you could survive.

You’re basically ascending to a bit higher than Mount Everest within less than an hour. So the ambient air pressure (‘thin’ air) will be equivalent to absorbing 1/3 the oxygen you’re used to (iirc), so you’d obviously pass out. I’d tether myself, just in case.

Having the oxygen concentrator would help with that but I’m not sure how the battery would be able to handle the cold. You’d have to keep it close to your body in a heavily insulated bag.

So I’d say, someone with a good amount of cash and technical know how should be able to survive, but someone very poor with some ill-fitting gear has a much lower chance of survival. That’s if they have even the slightest clue about what they’re about to go through.

So basically what you're saying is, if you can afford appropriate gear for stowing away, you can afford the ticket.

NextTrillion t1_iya5umm wrote

Well, yeah, I was trying to say that it’s not likely anyone that could survive would need to do it in the first place.

Don’t know, maybe a really thick sleeping bag and loads of those hot shots things, tie yourself down so you don’t fall out, and then you slip into a little coma and maybe you can thaw out and survive. People have survived really nasty snowstorms on Everest I believe for days. All of their extremities have died off due to frostbite, but their system kept on ticking.

I just like to think about all the various factors and I’m bored at work right now.

Is this cheaper than coach? Asking for a friend.

While you'd be in the air for much less time, the time in which you'd go without the thing you'd be missing (air, water) relative to the amount of time needed to kill you for missing it is much greater.

Just bring a piping hot mug of air and some super warm jammy-jams.
