How about a Cat Detroit hybrid? It's a steal at just over 1 mil. 1994 Halter Marine 128 ft Tug Boat in Chesapeake, Virginia, United States (IronPlanet Item #5608046)
A week's fuel would cost as much as that boat!
A 3306 Cat bow thruster! He must be shoving around aircraft carriers at the shipyards?
Fuel filters been there awhile.
