Who said I wasn't.

How does a concrete boat float at all.........amazing!!!

Displacement hull. As long as the volume of air buoyancy inside the hull is greater than the weight of the hull, it floats. Get enough water inside the hull and it sinks regardless of water depth. Think of all of the ships made of steel plate. Without a displacement hull shape, steel sinks like well....an anchor. ;-)

A displacement hull means it is non-planing,also the reason it floats has nothing to do with air bouyancy.Things float because their weight is less than the weight of the water the object displaces.Our lesson today is concluded,morons

Granted for simplicity I was using the word displacement liberally, but by your definition 'Things float because their weight is less than the weight of the water the object displaces.', steel and concrete weigh less than water.

Lesson for you, 'No one is above common courtesy'. ;-) LOL

Chill,only screwing around

Gravity.

Aliens!!

Archimedes' principle states that an object fully or partly immersed in a liquid is buoyed upward by a force equal to the weight of the liquid displaced by that object.
Interior volume cu.ft.> Weight of hull and occupants. 1 cu. ft. of water= 62lbs. Salt water is heavier 62.4lbs

GREAT answer! As Ensign Parker used to say on McHale's Navy, "Gee I love that kind of talk!"
