Yes and no. In order to go faster, a ship must reduce its air and water friction as much as possible, as friction force acts in the opposite direction as motion, ie slows the object down. However, it is friction that allows the propulsion system to 'push' the ship forward. This deals more with viscosity, which is *like* the friction of a liquid. In sailboats, it is the friction with the air that propels the ship.
Because friction is related to the area of contact and the vector of the velocity, it is ideal to have the least amount of surface area facing to the direction of motion, which is why most ships have a Vshape in the front.
how does friction help car tyres?
Friction is useful when you are trying to stop a car, but not useful in the pistons of a car's engine (It makes them less efficient).
It's useful
The friction is useful on a bike when you push it.
Friction is very useful but it has its own disadvantages. Friction causes wear and tear. Friction spoils the soles of our shoes. friction reduces speed This is all wrong some not useful types of friction are are when airplanes fly the friction causes heat that materials that will withstand which are costly.
Yes, friction is useful to ships because it helps them maintain control and stability as they move through water. Friction between the ship's hull and the water creates resistance, which allows the ship to steer and stop effectively. Additionally, friction helps prevent the ship from sliding or skidding on the water's surface.
Brakes are meant to have a lot of friction and it's useful.
No Friction Runes Computers
False
the friction from pushing the hull through the water is not useful as long as you're travelling.
It can be useful when a ball is catching

Sandpaper is high in friction but is not considered useful in terms of being helpful in a general sense.

The brakes! And the tires (no friction = no traction).
