On the same principle that little ships float. They simply weigh less than the water they displace.

Anything will float if it meets the following conditions:
1. It must be smaller than the ocean.
2. It must displace an amount of fluid greater than its own weight.
If you mean air ships, you can ignore Condition 1.

to add to the previous answer, water weighs roughly 60lbs per cubic ft. so the aircraft carrier Nimitz, with about 100,000 ton displacement has to displace about (100,000x2000)/60 = 3,333,333 cubic feet. it's about 1000 ft long, 134 ft wide at the waterline and has a max draft of 37ft. if it was a simple box under the water those numbers would give 4958000 cubic ft.
so can you imagine the hollow space under the water?

As everyone else has stated, displacement is why it floats.
An example of this would be trying to push an empty glass or container into water. As you push the container in, the water is moved, due to the empty space of the container. If you push too far, it sinks when water "takes" the space back.

Their hulls displace as much weight of water as they weigh.
