Why don't (some) ships capsize?

longdog

What is it you can't face?
I was looking at this picture and wondering how the fuck the thing manages to stay upright?

It must be 90% above water, pointy at the bottom and very top heavy.

Why doesn't it fall over?
 
Well about a third of the hull is below water, and that's where all the heavy bits are like engines, boilers, fuel and ammunition. Plus there's ballast down there.
The top third of the hull is hangars, with plenty of empty space and planes which are light compared to engines.

Sounds like my girlfriend in her high heels.:D
 
Same reason these don't capsize:

Quite a lot of hull below water (the part of the ship, not the city), which contains all the heaviest bits, including a large amount of ballast.
 
look you boobs...if the weight of the water that is displaced by the hull is greater than the weight of the entire ship then it will float. Water is very heavy.
 
1 ton per cubic yard, or 1 metric tonne per cubic metre...

Don't forget it is the Ark Royal so God holds it steady too... :)

You are the weakest link. Goodbye. :p

Water is not heavy, water is dense. Like you.

That doesn't look wrong, tho, like the first ship :)
 
Lot of bilge action going on with that aircraft carrier...








I suspect there's a secret submarine bolted on underneath.

Well, it's the old Ark Royal which currently doesn't go anywhere. It used to be in India, where, on delivery they pranged it into the harbour. Don't think it moved after that.

I want to know who was shelling it at the time, notice the splash just above and to the right of the ship?

I think that's an anti-submarine weapon (depth charge) it's just dropped...
 
I understand the theory but it just looks wrong. I find it much harder to get my head around than why planes do not fall out of the sky
 
it looks a bit rusty. you'd think with it being the ark royal and with kanda's dad just sitting about he could have got the paint roller out. perhaps a mural of her maj with a bazooka or something.

its majic aint it, there are in the ship, em seamen, thinking "fuck me i hope it dont sink cus i will fecking get wet" its the power of dont sink.

its the same way of how a plane flys, will power, its majical aint it govner :)
 
Of course some ships don't - Bad design & loading has created ships that might be OK in the calm or a light swell but become unwieldy & even dangerously unstable in bad weather etc. Hence the retro-fitting of sponsons (big bouyancy tanks along the sides) to ferries & so many other ships in the years after Zebrugge.

i thought zebrugge sank because they left the bow doors open, allowing water to enter, making it role more violently and that eventualy caused it to capsize.

Yeah -- they used to always leave the doors open -- shutting them as the ferry was already on its way :(
 
Leaving port with the bow doors part-open was a time-saving measure that Townsend Thoresen used to use on the Zeebrugge run - which came back to bite them on the arse with the Herald of Free Enterprise. Exacerbating the problem is the fact that Roll on-Roll off ferries need to have open decks with no subdivisions, meaning that once a large amount of water gets in it can slosh aorund and affect the ship's stability. Result:

It was in fact the worst peacetime accident to a British ship since the Titanic.

There've been other nasty accidents with Ro-Ros, mainly due to doors coming adrift in bad weather, but none as easily attributable to sheer negligence as Herald of Free Enterprise.

Wasn't she scrapped?
