a vertical metal pin attached to the leading edge of the rudder; it is fitted into the metal ring or 'gudgeon' bolted to the sternpost of a vessel. This provides the means for hinging the rudder on the sternpost and allows a rudder to be swung or turned as desired (by use of the tiller); where necessary ( ie. when the rudder needs to be removed or repaired) the pintles can be unshipped quickly and the rudder detached.
A type of hitch that uses a round ring called a lunette on the trailer end. Sometimes referred to as a "GI" or military type hitch. Pintles have closing jaws, locking the lunette in . These are also available in pintle/ball combinations.
