What statement is true concerning the purpose of an independent main thrust bearing where used?

Correct Answer: Option C — The main purpose of the main thrust bearing is to absorb axial thrust and to transmit the axial thrust developed by the propeller to the ship's hull.

The main thrust bearing is a critical component designed to transfer the axial force generated by the propeller to the ship's hull structure. By absorbing this thrust, it prevents the shaft from moving forward or aft, maintaining the propeller's position relative to the stern tube and hull.
