Which officer is responsible for directly controlling the engine and rudder angles of the ship?

The Conning Officer is responsible for directly controlling the engine and rudder angles of the ship. This role involves the coordination of navigation and the execution of maneuvering commands, ensuring that the vessel moves safely and efficiently according to the plan or during emergencies. The Conning Officer is typically tasked with directing the helmsman and engineering personnel to adjust the ship's speed and direction, making real-time decisions that affect the ship's movement.

In this role, the Conning Officer must maintain a clear understanding of the vessel's handling characteristics and respond appropriately to environmental and operational conditions. This requires good communication skills and situational awareness to ensure the safe navigation of the ship while directing the crew effectively.

The other roles mentioned have different functions: the Quartermaster of the Watch assists in navigation and maintains the ship's course information, the Boatswain's Mate of the Watch manages the deck crew and supervises deck operations, while the Junior Officer of the Deck supports the Officer of the Deck in maintaining situational awareness and assisting with watchstanding duties. However, none of these positions are primarily responsible for directly controlling engine and rudder angles, which is the main duty of the Conning Officer.
