Mid-Coast Marine Delivers Second Trawler And Tugboat

Mid-Coast Marine, Inc. of Coos Bay, Oregon, recently delivered the second 94-foot trawler Centurion to Continental Marine.

She is designed to participate in the North Pacific trawl fishing industry, with capabilities of switching quickly from bottom trawling to mid-water trawling. The vessel is equipped with four fish holds totaling 5,100 cubic feet and chilled by two Wescold 24-ton R-22 Port-A-Chillers with Carrier compressors.

Overall length is 94 feet, molded beam 26 feet, and depth 11 feet.

The Centurion is powered by two Cummins KTA 1150 diesel engines, with Twin Disc 5:1 reduction gears driving two stainless- steel propellers in Kort nozzles. The main engine room is located aft, minimizing shaft length and reducing noise and vibration in the living quarters. The aft engine room also houses two 135-kw, Cummins auxiliary generator sets and one 30-kw, Detroit Diesel Allison emergency generator.

A passageway between the fish holds permits easy access between the forward and aft engine rooms; the forward engine room contains all the smaller auxiliary machinery for the electrical, bilge, hydraulic, fresh water, and steering systems. To round out the efficiency of the vessel, a complete package of electronics and communications equipment was provided by Whatcom Marine Electronics of Seattle.

Shortly after the Centurion was completed, Amak Towing Company of Ketchikan, Alaska, took delivery of their second 55-foot tugboat from Mid-Coast, the Ardie. Her overall length is 55 feet 6 inches, with a beam of 19 feet, depth of 8 feet 9 inches, and draft of 7 feet 6 inches.

The twin-screw tug is powered by two Caterpillar 3408TA diesel engines driving 54-inch, stainless-steel propellers in fixed nozzles through Twin Disc MG514, 4.5:1 reduction gears.

Two Perkins 4-236, 30-kw auxiliary diesel generator sets provide ac power. All engines are cooled by Fernstrum grid coolers. Aurora Communications of Ketchikan provided the electronics and communications package. The vessel is equipped with Mathers controls, Argus Auto-Watch alarm systems, and a Microphor sanitation system.
