USS Cairo


Vessel Details

Designed by the noted naval architect firm of Townsend Marine Designs in South Portland, Maine there are more than the Z-drives to catch the attention of the industry. The octagonal wheelhouse, with its 360-degree windows, is also reminiscent of a harbor tug. The wheelhouse sits atop a deck cabin with sloped sidewalls to provide optimum visibility to the working deck fore and aft. Unlike other fleet boats, the new vessel will have push knees both fore and aft. On deck there will be two Win-Tech 65-ton winches for face wires and a single Win-Tech Capstan. A Palfinger PK-12000 crane will be mounted forward on the first deck level.

Main propulsion will be provided by a pair of Tier III compliant Cummins QSK19-M engines each delivering 750 HP through Twin Disc HPTO366 gears to the Z-drives. These drives will be Thrustmaster 750 Azimuth Thruster- TH750 MZ. A pair of Cummins QSB-7-powered 150 kW generators will provide auxiliary power. In anticipation of the new Subchapter M regulations for inland towboats, Carline and their design team have worked to approximate the, as yet unconfirmed, guidelines.

As with most fleet towboats this will be a day boat with a galley but no need for overnight accommodation. Tankage will include 16,000 gallons of fuel, 3,000 gallons of water and 400 gallons of lube oil.
