Rudder Meaning in Sailing

The rudder consists of a flat blade located underwater at the stern of the boat, used for steering. It is connected to a tiller or a steering wheel; when the rudder is turned, the flowing water creates pressure that pushes the stern sideways, changing the boat’s heading. One specific example involves a sailor pushing the tiller to the left to move the rudder, which causes the boat to turn to the right (starboard). The size and shape of the rudder affect how responsive the boat is to the helm. If the boat leans too far (overheels), the rudder can sometimes lift out of the water, causing a loss of control known as a ‘spin-out’ or ‘broach.’ It is the primary control surface for the navigator.
