PMI Develops Z-Drive Tug Handling Program

The Pacific Maritime Institute, in partnership with Captain Jeff Slesinger, has developed and implemented a three-phase Z-drive Tug Handling Program. The program is oriented towards Captains and Mates that are experienced Tug Operators, but have little or no experience driving Z-drive tugs. Utilizing the Pacific Maritime Institute’s state-of-the-art Tug Simulator, the Program guides operators through a series of “at sea” situations that are specifically designed to focus on and hone the specific skill sets required to operate a Z-drive tug. At the end of the nine day course of instruction, operators come away with a fundamental understanding of, and an ability to perform, the unique boat handling skills required to maneuver Z-drive tugs in light tug, barge, and ship assist work.
