If a boater falls overboard, will he/she float or sink if unconcious?

Without a lifejacket, the boater will still most likely continue breathing, even if unconscience.  The body is trying to sink, but lungs filled with air will keep the body afloat.  If the person breathes in and his or her lungs fill with water, the person will definitely sink. However, after drowning, the gases in the blood stream accumulate, allowing the dead body to rise to the surface of the water.

you will probably fall over.

Not if the water is a couple of feet above your chest.

They don't sink.  They float.  Even if you tie them to a weight, the gasses that form in them make them float.  Better to chop them up in tiny pieces...

No, unless they are at the water surface at the point of impact or a few feet away. The reason is that electrical charge weakens, (dissipates),  dramatically fast with distance, in the water.\nDan.

Nobody seems to have figured this out yet. The rock in the canoe displaces a volume of water equal to its mass, as part of the total displacement of the canoe. When you drop the rock overboard, it displaces a volume of water equal to the volume of the rock. Since rock is denser than water (assuming we're not dealing with pumice here) the rock now displaces less water than it did in the canoe. So the water level in the pool will fall.\n\nIn the case of pumice or other floating rock, it displaces its mass in water in either case and the water level is unchanged.

Assuming that the cardboard is water tight:\n\nBuoyancy force = Weight of water displaced\n\n(mass of boat)*g = (desity of water) * 4ft*5ft * height * g\n\n81820g = 1g/cm^3 * 18581 cm^2 * height\n\nheight = 4.4 cm, which is the waterline when the boat weighs 180 pounds.\n\nYeah, it sounds quite unbelievable, but most boats that large with a height of 1 foot can hold over 1100 pounds of weight before completely sinking.

Funny you asked...one time, my younger sister and I were on a wave runner chasing this boat full of really cute guys. Granted, I was about 17, and she was 14.Anyways, the boat was making some killer wake and I throttled it and we ended up hitting this HUGE WALL OF WATER and my sister literally FLEW off! I felt really bad, and to this day, she has a dent in her ankle from where she smacked it when she flew off. Hehe.

No, wind wont bother a Kayak, but once that storm kicks up a massive swell and your tryin to paddle through 25ft + surf with white wash that would de-rail a train and youre stuck in the middle of that, its only a matter of time untill you get swallowed up by hell and pushed 20 foot under water doing backflips and sommersaults uncontrollably like youre in a high powered washing machine. \n\nAnd the whole time this is happening you know that youre probably about to die, and that you only have a few seconds of air left in your lungs all the while youre trying to get back to the surface to draw a breath but the power of the water is just pushing you down deeper and deeper and you cant fight it, you just have to accept youre as lifeless as a ragdoll as your body is dragged hundreds of metres underwater. \n\nBy the time this monster has lost its power and you can get back to the surface for air, hopefully you are still alive.

your body will float, but with sufficient wave action you still might drown since you cannot breathe water.

The question is...Can anyone walk on water???? NOT!!!!!!

If the water is full of air bubbles, its density is reduced. You loose buoyancy and sink.\n\nWhen there is a natural gas blow out under floating oil platforms, they have been known to go down almost instantly.

He'll get banged around by inertial forces. Every time the ship moves left, he gets thrown to the right, etc. Also, whichever direction the ship accelerates in will seem like up. I imagine he'd be bruised, disoriented, and maybe nauseated.

your body is accelerating at the same rate of the car so no matter what you do, you will impact the water at 9.8 meters per second squared. that should kill you. the same happens in falling elevators. if you jump before it hits the bottom, you will break your legs or die.

they float because their density is actually less than water.  don't believe me?  catch a duck, weigh it, then submerge it in water and calculate its density.  then look up the density of water.  the duck will have less, i assure you.  (and good luck with dealing with a seriously angry duck!)\n\nsomething can only float if its total density is less than that of water.  what about a steel ship, you might ask?  well, the inside of the ship is filled with air, and the total density of the ship considering the steel AND the air, is less than that of water.  water is actually quite heavy.

depends where if falls.

If you don't, some of the water will evaporate into the air, so it will seem like you "lost" some water.
