How does a heavy boat float? ... A boat, or any other object designed to float, is based on a theory by a very old guy, even older than Capt. Matt. Though he is old and, by the way, dead, he was really a cool guy and his name was Archimedes (Ark-i'-meed-eez). ... Find out why some boats ride through the water and some ride on top.

The principle of buoyancy is called Archimedes' Principle, ... Steel boats float, however, because they are hollow and shaped to displace a volume of water that weighs more than the boat's weight. Ships are often rated by their displacement. Displacement is measured in units called tons, which are the weight of the...

"Buoyancy" is the upward force of water that works against an object's mass -- ... Ballast- Heavy material that provides wieght and stability. In boats, ballast is usually water. Ballast is reduced by introducing air. That's exactly how a submarine is able to float or sink! ... Buoyancy and Boats - Terms:

The boats will then be tested by floating them in a pool or sink of water, and then adding mass until they sink. While students may not be able to articulate it, they will intuitively begin to understand the scientific laws required for the design of the boat, i.e. buoyancy and Archimedes Principle.
