read up on Archimedes' Principle he describes buoyancy mathematically

Good old Archimedes figured this one out about 2500 years ago. Ships float because they weigh less than the water they displace. A bar of iron sinks. Take the same bar, flatten it out and make a bathtub shape out of it so that the water it pushes away weighs more than it does. Voila! It floats.

It's called displacement. The weight of the water surrounding the ship is actually heavier than the ship itself. The hull is designed to displace the water so that the ship can move through the water and keep the majority of the hull on top of the surface .

This question that seems to repeat itself. You might want to search previous answers for more information, but here is my 2-points worth.
The total weight of any object is the sum total of all the downward forces of gravity. For an object ot float it must displace, or push aside, an amount of water equal to the weight of the object. This is called displacement and is defined in Archimedes' principle. For more information check out this link: http://education.yahoo.com/reference/encyclopedia/entry/Archimprin

The weight of the water it displaces outweighs the ship itself. This creates bouyancy. :)

Because the buoyant forces holding it up are greater than the force of gravity pulling it down.
