With respect to a "pusher" type azimuthing thruster, what statement is true?

Correct Answer: Option D — With an azimuthing angle of 0o, the azimuthing thruster's propeller is directly abaft of and in the wake of the gear unit.

In a pusher-type azimuthing thruster, the propeller is located aft of the gear housing. Consequently, at a zero-degree azimuth angle, the propeller operates in the wake of the gear unit, which can affect inflow velocity and cavitation characteristics compared to a tractor-type configuration.
