Had one of the big thrills of my life yesterday. Got to ride on a brand new tug boat here in Savannah. A 5100 HP, twin Z drive (the entire drive unit pivots 360 degrees and consists of two hydraulically driven power nozzles). This thing was awesome. Twin 2550 hp EMD engines. The generator was a CAT 3406. Spent six hours on this bad girl turning and parking container ships and tankers. The control system consists of two small joysticks. Rotation of the joysticks rotates the individual thrust nozzles so a clutch isn't necessary. Individual throttles are located integral to the joystick and are controlled by the thumb. The tug can come alongside a ship running slow ahead, adjust nozzles so the the tug is running sideways, makeup lines to the ship, and then adjust nozzles so it is actually running backwards without ever stopping or "clutching" the drive units.
