Buoyancy
bouyancy
Nothing "floats in gravity." Floating in a result of the buoyancy force provided by a fluid. Balloons float because of the buoyancy force from air. Boats float because of the buoyancy force from water. Objects that appear to float in space are usually in orbit, which is actually a state of freefall.
A ship can float on water because of buoyancy. The shape of the ship and the displacement of the water it pushes aside when it enters the water create an upward force that counteracts the downward force of gravity. This buoyant force allows the ship to float and support its own weight.
Provided the boats and the ships displace their weight in water without the water coming inboard, they will float and not sink. A boat made of wood is likely to float even when full of water because wood tends to float. It is all to do with displacement and freeboard.
no design matters. it is the force of water resistance and upthrust that are level that allows any boat to float

If boats didn't float, they wouldn't be boats, they'd be anchors.

The boats displace water in such a way that they remain afloat. Hence why most boats have a V hull shape. This allows them to displace the water and remain afloat, if on the other hand you put to much in a boat it will eventually sink.
