Ships float because they displace enough water to create an upward force called buoyancy that is greater than their weight. Coins sink because they are denser than water and therefore displace less water than their own weight.
A pencil floats, a human no float, a feather floats, paper floats, ice floats, keys do not float, rocks do not float, coins do not, flip flops float. Second answer: I think you meant to ask, 'What floats and then some time later starts to sink. If that is what you meant, the answer is: There are absorbent substances which float when dry, then after absorbing water while they are floating, they increase in density and then sink.
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.
Materials float or sink depending on their density. If an object is less dense than the liquid it is placed in, it will float. If it is more dense, it will sink. The buoyant force acting on the object helps determine whether it will float or sink.
Density is the property that causes a ball to sink and a boat to float. If an object is denser than the liquid it is placed in, it will sink, while if the object is less dense than the liquid, it will float.
Big metal ships are designed with a specific shape and structure that displaces enough water to generate buoyancy, which allows them to float. The weight of the ship is spread out over a large enough area, preventing it from sinking. The principle of buoyancy, based on Archimedes' principle, explains why objects float or sink in a fluid.
Ships don't sink because they are more boant then the water they float on. Ships don't sink because they are more boant then the water they float on.
Because they don't sink.

The general rule is that an object will sink if it has a greater density than the liquid in which it is placed.
It floats, but after a while silk will sink.

No. Cruise ships and aircraft carriers float very nicely.
Yes, it would actually float. While less liquids sink right to the bottom
Submarines are designed with enough ballast and control systems to allow them to submerge and surface as needed.Surface ships are designed only with enough ballast and control systems to keep them on the surface. While they can sink just as well as submarines can, their ability to re-surface without a salvage operation is non-existent.
