Resistance. Water has a lot of resistance.
resistance is useful when a plane is flying in the air, air resistance. it is also useful when a boat is floating on water, water resistance.
By overcoming the resistance of the water by some means of propultion.
Water resistance on boats can be reduced by ensuring the boat is as streamlined as possible. This will allow the water to flow past it much more easily, thus reducing resistance.
