74,000 pounds or 37 tons  (fuel tanks not totally full)

*Note:  These are a measure of the cargo capacity of a ship’s hull below the decks, based on volume (cubic feet).  They are not particularly meaningful for a tug boat which does not carry cargo on board.  The gross tonnage includes all area below deck, while the net tonnage excludes space for engines/machinery, fuel tanks, crew’s quarters, etc.  
Neither measure has any direct relationship to the actual weight of the vessel.
