What keeps a boat from floating away?

A boat stays in place and doesn't float away primarily due to the anchoring system, which typically consists of an anchor that is dropped to the seabed, creating friction with the ground and holding the boat in position. Additionally, mooring lines attached to docks or buoys provide stability by securing the boat in place. The buoyancy of the boat allows it to float, but these anchoring methods prevent it from drifting with the current or wind.
