The boom boat’s larger yard-mate, the Jennie B., was named for the five-year old daughter of Bob Berto who, with his brothers-in-law Chiff and Jim Taro, is a principal in Southeastern Stevedore in Ketchikan. The tug will be operated by Revillia Towing Company, which is managed by Jim Taro. He said that the tug will be used for barging, towing log booms, and ship handling, particularly the tour ships that call on Ketchikan. Swanson called the Jennie B. “ one powerful boat” with its two KTA-2300 Cummins diesels developing 950 hp at 1,800 rpm. Engines and supporting equipment were supplied by Cummins Oregon Diesel, Inc., Portland, in association with Alaska Leasing Sales & Service which will provide support in Ketchikan. Engines drive two 70-inch, four-bladed props in 71-inch Kort nozzles through Twin Disc 530 6.06:1 reduction gears. Mathers equipment-with air supplied by Quincy compressors-is used for engine controls. Engines are cooled by Fernstrum keel systems A Worthington positive displacement fuel transfer system, with Racor 800 fuel filter, provides fuel from tanks with a total capacity of 15,000 gallons. The Hough-Wagner steering system utilizes both standard wheel and jog levers at the two wheelhouse stations and the deck station aft. The Almon-Johnson towing winch originally came off a minesweeper. Surplus winch and windlass/capstan were brought from William Drury, Seattle. Fitted with a high-speed, high-torque hydraulic Hagglund motor, the winch has a bare drum pull of over 60,000 pounds. The anchor windlass provides a capstan for” working on the head rope” in ship handling as well. Two Vickers fixed-displacement pumps are driven directly off the starboard engine. Swanson said that the two pumps-with electrically operated dump valves-can be operated separately or combined to run the capstan and towing winch. The system has enough capacity for later installation of a knuckle boom crane, Swanson said. The system he explained features a short flow pattern to avoid undue system heat, with dump valves returning fluid directly to the 300-gallon hydraulic fluid tank. Cascade Machinery supplied the Flow-Max bilge and main water system pumps. Two Isuzu engines with Lima 30-kw generators feel the ship’s service system/ Apollo Marine, Portland, built electrical boards and control panels to Mid-Coast specifications defined by Mid-Boast electrical engineer Jim Stephens. Jennie B. characteristics encompass a 65-foot one-inch LOA, 23-feet 11-inch width, nine-foot six-inch depth to the main deck, and a nine-foot draft. The longitudinally stiffened hull provides tankage for 300 gallons of lube oil and 1,500 gallons of water. Hull hydrostatics and stability were analyzed by computer. Accommodations include a single stateroom for the skipper, a three-man bunkroom in the forecastle, and dinette with seating for six, and a galley equipped with Jenn-Air range and Kenmore microware. Taro said that while the boat at times will have to provide crew living space at construction sites, the boat will usually operate with a two-man crew-a boat operator and an engineer deckhand. Wheelhouse windows of ½ -inch Lexan are fitted with Speich clear view screens. The electronics suite, from Puget Sound Instruments, Seattle, features Furuno radar and recording fathometer, Sperry 8T autopilot, Apelco 360 sounder and Trident 11 loud hailer: Raytheon 720 sounder and 55 VHF radio-telephone: Data Marine 2300 speed log; Cobra 40-channel CB; AiPhone intercom: and Hull 922 SSB. Swanson pointed out that the boat was well equipped with bottom sounders since “Alaska towboat operators have to navigate by the bottom as bottoms can change drastically when running near shore or up rivers.” Lee said that Mid-Coast can build a boat like the Jennie B. in about four months from contract signing and he has undertaken a vigorous effort to keep up the flow of work for what he calls a “young dedicated work force”.
