Which term describes the structure that holds the rudder in place by providing a pivot located on the stern post?

Pintles and gudgeons form the hinge that lets the rudder move from the stern post. The pintles are projections on the rudder, and the gudgeons are the matching sockets or bearings on the stern post. As the rudder turns, the pintles slide within the gudgeons, creating the pivot axis that holds the rudder in place while allowing it to swing under steering loads. This setup is what provides a stable, rotating connection needed for effective steering. Toggle pin isn’t the hinge for the rudder; it’s a type of fastener used in other assemblies. Seine float is a buoy used in fishing gear, and a Kort nozzle is a propeller duct for thrust and efficiency, not the rudder pivot.
