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

AWith an azimuthing angle of 0o, the azimuthing thruster's propeller is directly abaft of the gear unit, but the gear unit is in the wake of the azimuthing thruster's propeller.

BWith an azimuthing angle of 0o, the gear unit is directly abaft of and in the wake of the azimuthing thruster's propeller.

CWith an azimuthing angle of 0o, the gear unit is directly abaft of the azimuthing thruster's propeller, but the azimuthing thruster's propeller is in the wake of the gear unit.

DWith an azimuthing angle of 0o, the azimuthing thruster's propeller is directly abaft of and in the wake of the gear unit.

AI Explanation

The correct answer is D) With an azimuthing angle of 0o, the azimuthing thruster's propeller is directly abaft of and in the wake of the gear unit. This is correct because in a "pusher" type azimuthing thruster, the propeller is located behind the gear unit, which means that with an azimuthing angle of 0 degrees, the propeller will be directly behind and in the wake of the gear unit. The other options are incorrect because they do not accurately describe the relative positioning of the propeller and gear unit in a "pusher" type azimuthing thruster with a 0 degree azimuthing angle.
