Ships don't need air/oxygen...Drowning does not mean you have to sink...It just means your lungs has filled with water so it can't get air...Generally ships don't sink because they're hollow but fill 'em with water...

Oh BTW dead bodies usually float that's why the mob gives you "cement shoes" to "sleep with the fishes" ;)

Boyancy! About 1/2-1/3 of ship floats above the water (and is filled with air and cargo) The air increases the weight very little,but the cargo "loads the ship" and makes it sink proportionatly to the weight! If the weight is too much, -the ship is too low in the water, and it doesn't take all that much to sink it. When the water goes in, the air ( including oxygen) goes out, and the ship sinks (it doesn't rise again either)!

Humans on the other hand have very little bouyancy, and they require a certian amount of "power" exerted to keep the head above the water! There are ways to maintain bouyancy by certian floating positions, and kicking of the feet, - but for some reason the back of the body "floats" better than the front! Since the mouth is on the wrong side of the head, it is hard to breathe that way! When all the air goes out and is displaced by water, the body sinks for a period of time, -- but it still has some air inside the body, also nitrogen and a few other gases (all trapped in the blood). End result is tht the body "bloats" and becomes more bouyant again and rises to the surface . Unfortunately it is way to late to do the person any good because he is long dead by then!!

I guess technically the "ship drowns" too, since it looses all it's air (which contains oxygen). the engines won't run without air and oxygen, and if the engines die, and the ship sinks-- it is "dead too".

A ship floats because of bouyancy. When that is discontinued a ship will sink. We just spoke with a sailor whose sailboat hit a container that had fallen off a container ship and it sunk in 10 minutes because it was holed and no longer was displacing an amount of water greater than its weight. Fortunately he carried a life raft and an EPIRB which signaled where he was and he was picked up in a day. Everyone should wear a life jacket while boating, but there are still many reasons why they might drown.

Your body is mostly solid a ship is mostly hollow.A ship that fills itself up will start to sink deeper and deeper in the water until until the water floods into the ship. A body has only the lungs and some of its intestinal tract that is full of air. This is too small a percentage of your body mass to float. However if the water gets dense enough like in salt lakes bodies float quite well.

Hypothermia degrades one's ability to stay active in the water. The cold affects reasoning. Much like falling asleep in the snow, water as hot as 90 F can easily kill the best swimmer, with or without a life jacket.

b/c they don't breathe therefore they can't die. Duh!
