An object will float on water if it has less density than the water.
An object will float on water if it has less density than the water.
It displaces an equal or greater amount of water than its own weight.

Ultraoversimplifying it, the coin is solid metal all the way through and weighs more than its volume of water, the ship has a large space filled with air inside it resulting in the weight of the ship and cargo being less than the weight of the volume of water it occupies.This is called buoyancy: the coin has negative buoyancy and sinks, the ship has positive buoyancy and floats.
a ship
The basic reason that a ship floats is that the enclosed volume in the ship's hull is greater than the volume of water which has the same mass as the ship.
Weight of ship = weight of (displaced) water.
can you take abottle of water with you when you get off the cruise ship at the bahamas
Because the weight of the water that they displace is greater than the weight of the ship.
a ship floats on the water and a submarine can go underwater and on top of the water
A stone has a greater density than water; a ship, less.
