In a binnacle, you would typically find a compass. A binnacle is a housing or stand that holds the ship's compass on a vessel. It is typically located on the bridge or helm of a ship. The compass in the binnacle provides essential navigational information to the ship's crew, allowing them to determine the vessel's heading and navigate the desired course. The binnacle helps to protect the compass from the elements and provides a stable and visible location for the compass to be read by the helmsman or navigator.
