Rudders

A rudder is a flat piece attached to the back of a boat or aircraft's tail that acts like a steering wheel. When the rudder twists to one side, it pushes water or air in a way that turns the vessel in that direction. It helps you control the direction you're going by changing the flow around the craft's rear, allowing precise navigation. Rudders are essential for steering, providing balance and maneuverability in both ships and aircraft.
