the friction from pushing the hull through the water is not useful as long as you're travelling.
Rowing a boat increases friction. The oars create resistance against the water, which generates friction that helps propel the boat forward.
Brakes are meant to have a lot of friction and it's useful.

how does friction help car tyres?
stopping cars Friction is useful to start a fire with sticks.
Sandpaper is high in friction but is not considered useful in terms of being helpful in a general sense.
No, it is not. Rolling friction occurs when a round object rolls across a surface. A boat on the ocean is not in contact with any solid surface. Instead of rolling friction the boat is subject to drag.
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 is useful
The force used when you step from a boat creates an equal reaction on the boat, which has very little friction with the water. If the boat were on the beach, friction with the sand would prevent it from moving very much.
The primary type of friction involved while rowing a boat in a lake is fluid friction, also known as drag. This occurs between the boat and the water, as the boat moves through the water, creating resistance. Additionally, there is also static friction between the oars and the water, which helps propel the boat forward as the oars push against the water. Both types of friction are crucial for effective rowing.
