A boat will float sideways if the water is too shallow and it touches bottom. Boats will float higher in water with greater salt content. If you fill a boat with water it begins to sink deeper. It all depends on whether you are talking about water outside the boat or water inside the boat.
The water density is higher than the boat's therefore it floats on the water.
Wood floats in water.
If it floats on the water.
The same way anything floats, by displacing an amount of water that weighs as much as it does. Airplanes that are meant to float on water typically either have boat-like hulls or floats whose purpose is to displace enough water to allow the airplane to float.
When the boat is first lowered gently onto the surface of the water, the surface level rises slightly, regardless of the boat's size, shape, or weight, or what it has on board. The boat floats because it has displaced an amount of water that weighs exactly as much as the boat does. That means it has pushed some water out of some volume that the boat now occupies. The water it pushed aside has to go somewhere, and the surface level in the pool must rise.
Simply put, the displacement of any boat is the amount of water the hull displaces when it floats. The weight of the water being displaced will be equal to the weight of the boat...assuming it's still floating, that is.
A boat floats by keeping water outside, regardless of any material
raft, boat
"You look fit to be tide." "Going my way?" "Whatever floats your boat."
An aluminum foil boat floats because it is more dense than water, therefore the surface tension of the water is able to hold the boat up.
If your boat capsizes and floats away, there are various things that you can do. The most important thing is to try and float and shout for help. If you are not very far from the shore, you can swim out of the water.
As per Archimedes principle for floating the weight of the displaced water has to be equal to the weight of the boat. Hence for more water to get displaced the boat has to sink more.
