ship propeller
Vessel's spinning blades
A ship propeller is the rotating blade assembly that drives a vessel through water.
The angled blades spin on a shaft connected to the engine, pushing water backward to create forward thrust.
Most modern ships use propellers with three to six blades: The ship's propeller churned the water into white foam.
Also called a screw or ship's screw.
