Which of the following is NOT a rudder type?

Explanation:
Understanding rudder types comes from how much of the rudder sits in front of the hinge line. A balanced rudder has a portion forward of the hinge, which helps counteract the forces and makes the helm lighter. A semi-balanced rudder has some forward portion, but less than a fully balanced one. An unbalanced rudder has the entire surface behind the hinge, so more effort is needed to steer. A propeller, on the other hand, is a propulsion device that creates thrust to move the boat, not a steering surface. It affects motion and can influence steering indirectly through wake or thrust changes, but it isn’t a rudder type. So, the item that is NOT a rudder type is the propeller.
