stirt
Stirt is a term that can refer to several different concepts, primarily in the context of sailing and mechanical stirring. In sailing, a "stirt" or "stirrup" is a piece of rope or webbing that is attached to a spar, such as a boom or a gaff, and looped at the bottom to form a stirrup-shaped opening. This opening is used to attach a sail or other rigging. The term can also refer to the foot strap used by windsurfers and kitesurfers to secure their feet to the board.
In a mechanical context, "stirt" can be a misspelling or colloquialism for "stirrer" or "stirring rod." This
