Rudder Stock Assembly

Rudder Stock Assembly refers to the complete set of components that make up the rudder stock, which is a vital part of a ship's steering system. It is classified under the supply class Marine Hardware And Hull Items in the supply group Ship And Marine Equipment.

The rudder stock assembly typically includes the following components:

1. Rudder Stock: This is the main shaft or rod that connects the rudder blade to the steering mechanism. It provides the necessary strength and stability to control the movement of the rudder.

2. Rudder Blade: This is the flat, vertical surface that is attached to the rudder stock. It is responsible for changing the direction of the ship by deflecting the water flow.

3. Rudder Bearings: These are the bearings or bushings that support the rudder stock and allow it to rotate smoothly. They are usually made of materials such as bronze or synthetic materials that can withstand the marine environment.

4. Rudder Carrier: This is the housing or bracket that holds the rudder stock in place and provides additional support. It is typically attached to the ship's hull or stern structure.

5. Rudder Trunk: This is the enclosed space or compartment in the ship's hull where the rudder stock assembly is housed. It protects the assembly from external elements and provides a streamlined flow of water around the rudder blade.

6. Rudder Stock Seals: These are the seals or gaskets that prevent water from entering the rudder trunk and ensure a watertight seal around the rudder stock.

The Rudder Stock Assembly is an essential component of a ship's steering system, allowing the captain or helmsman to control the direction of the vessel. It is designed to withstand the forces and stresses encountered during navigation and maneuvering at sea.
