Which of the following propulsor types represents the proper terminology for a Z- drive?

Correct Answer: Option A — Azimuthing propulsor

A Z-drive configuration employs a vertical shaft from the prime mover to a horizontal propeller shaft via two sets of bevel gears, forming a 'Z' shape. Because the entire unit can rotate 360 degrees, it is categorized as an azimuthing propulsor, providing superior vessel handling and station-keeping capabilities.
