Question 161General Subjects - 1st Asst/Chief
70% to passWith respect to a "tractor" type azimuthing thruster, what statement is true?
AWith 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.
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 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.
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 B) With an azimuthing angle of 0o, the gear unit is directly abaft of and in the wake of the azimuthing thruster's propeller. This is because in a "tractor" type azimuthing thruster, the propeller is positioned forward of the gear unit. When the azimuthing angle is 0 degrees, the gear unit is directly behind the propeller and within its wake, which can impact the gear unit's performance and efficiency. The other options are incorrect because they do not accurately describe the relative positioning of the propeller and gear unit in a "tractor" type azimuthing thruster with a 0-degree azimuthing angle.
