Gudgeon Meaning in Sailing

A gudgeon consists of a sturdy metal fitting with a hole, attached to the stern (transom) of a boat to support the rudder. It works in conjunction with a ‘pintle’ (a vertical pin) on the rudder to create a hinge that allows the rudder to swing from side to side for steering. This hardware must be incredibly strong and perfectly aligned to handle the constant pressure of the moving water. One example involves a sailor checking the gudgeon bolts for signs of looseness or corrosion during a seasonal inspection. If a gudgeon breaks, the boat loses its ability to steer, which can be catastrophic in a narrow channel. Most modern gudgeons are made of stainless steel or bronze for maximum durability in the marine environment. It is a critical, though often overlooked, part of the boat’s primary control system.
