(NORTHPORT, Ala.) — Parker Towing Co. has added the Super Tiger-class Chipper Rabbit to its fleet as a newly constructed workboat built by Serodino Inc. in Chattanooga, Tenn.
The 1,368-horsepower vessel measures 60 feet by 24 feet by 8 feet and is configured with a twin-screw propulsion system powered by two Mitsubishi S6R-Y3 Tier 3 engines, each rated at 684 horsepower at 1,800 rpm. The propulsion package was selected to support the vessel’s operating profile while providing a dependable platform for day-to-day operations.
Chipper Rabbit is one of two Super Tiger-class vessels built by Serodino for Parker Towing. For the propulsion package, Parker selected Mitsubishi’s fully mechanical S6R platform, a proven engine design known for its straightforward operation and ease of maintenance.

“The fully mechanical propulsion package was a strong fit for what we were looking for in a vessel,” said Chas Haun, executive vice president at Parker Towing. “Serodino delivered a vessel that aligned well with our operational needs, and the combination of that vessel with the support available through Laborde Products gave us confidence in the package and its long-term operation.”
Laborde Products supplied the propulsion package and worked alongside Parker Towing and Serodino throughout the project. The engine selection aligns with the vessel’s intended application while supporting long-term operational requirements.
“The S6R continues to be a dependable platform for inland applications,” said Dan Walsh, sales representative at Laborde Products. “For a vessel like the Chipper Rabbit, it provides a straightforward package that supports reliable operation and long-term serviceability.”
