This "ring" is one of the reasons. This 16-foot "ring" is called a Kort nozzle...and it adds literally 25 to 40% more thrust than the con-ventional open-propeller can deliver.

McAllister is adding four more of these high powered Kort nozzle type tugs in the multimillion-Moy 15, 1969 dollar expansion of its fleet. McAllister has the power to get your job done right.
