The term 'steering apparatus' refers to the HELM, which is a four-letter word. The HELM is a device used to control the direction of a ship or other watercraft. It is typically located at the stern of the vessel and is operated by a wheel or tiller. The HELM is connected to the rudder, which is a large fin-like structure that is used to steer the vessel. The HELM is an essential part of any watercraft, as it allows the captain to control the direction of the vessel.
