Mid-Coast Marine Yard Delivers

Its First Twin-Screw Tugboat

Mid-Coast Marine, Inc. (for- merly Nelson Log Bronc) of Coos

Bay, Ore., recently delivered its first 65-foot, twin-screw tugboat, the Andy Head (shown right), to Alaska Timber Corporation.

The new vessel will perform tow- ing and ship-handling jobs for the

ATC plant in Klawock, Alaska.

Designed by Jack Wilskey to meet American Bureau of Ship- ping and U.S. Coast Guard stand- ards for structural strength and stability, the tug has a beam of 23 feet 10 inches and draft of 9 feet. The entire vessel is pro- tected by extruded rubber "D" section fenders, plus extra pro- tection on the bow to assist in the ship-docking process.

Main propulsion is provided by two Cummins KT2300M V-12 die- sel engines equipped with air starting, driving 68-inch-diame- ter, four-bladed Coolidge propel- lers in Mid-Coast Marine nozzles through Twin Disc MG530, 6:1 reverse/reduction gears. Keel cooling for the main engines is provided by Fernstrum units.

Free-running speed on trials was 11 knots. The vessel has fuel ca- pacity of 12,400 gallons and car- ries 3,000 gallons of fresh water.

Power and maneuverability in a small package are the prime char- acteristics of this heavy-duty workboat.

Engine and steering controls are provided at three locations.

Full follow-up hydraulic steering is installed, in association with a

Sperry MK8 autopilot system.

Mathers air-operated engine con- trols are provided at the same lo- cations — port and starboard in the pilothouse and at the aft tow winch station.

Electric power for the various engine room pumps and heating system is provided by two Lima 30-kw ac generators, driven at 1,200 rpm by GM Detroit Diesel

Allison model 3-71 engines. A 12- volt battery starting system is provided for the auxiliaries, as well as for emergency lighting and radio power.

Staterooms for four crew mem- bers are located in the forecastle;
