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.
no
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.
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.

Brakes are meant to have a lot of friction and it's useful.
yes friction is very useful because it help objects not to slide or slip
stopping cars Friction is useful to start a fire with sticks.
No Friction Runes Computers
the friction from pushing the hull through the water is not useful as long as you're travelling.
friction is useful for: you to walk It is needed for braking Can be used to produce heat
It can be useful when a ball is catching

High friction is useful for lots of things, like a goalkeeper's glove. The more friction there is between the glove and the ball, the easier it is to get a hold of it.
