ABSTRACT:
This invention is a tug type vessel which can be operated in shallow as well as deep water, is relatively powerful compared to its overall length, and is versatile in that additional drive units can be added as required to form an integral propulsion system. This is accomplished through the use of a plurality of floats interconnected with pivotable power units supported therebetween.
