Reference Answer
### (a) How the Weight of the Rudder is Carried
The entire static weight of the rudder, rudder stock, and tiller assembly is a significant vertical load that must be transmitted to the ship's hull structure. This is primarily achieved by a specialized thrust bearing known as the **Rudder Carrier Bearing**.
#### 1. Rudder Carrier Bearing
This is the principal component responsible for supporting the rudder's weight, especially in modern spade or semi-balanced rudders where lower pintle support is minimal or non-existent.
