UPSCO Launches Hull Number 001 —A 120-Foot Tug For An ITB Participants in the Hawaii Section meeting were (left to right): Capt. Thomas Marnane, Commander of the Pearl Harbor Naval Shipyard, Rudy Choy, president of Aikane Corporation, who delivered a paper on hydrofoil catamarans, and Dr. Frederick Munchmeyer, who was honored as immediate past chairman. SNAME-Hawaii Discusses High-Speed Catamaran Hydrofoils The Upper Peninsula Shipbuild- ing Co. (UPSCO) in Ontonagon, Mich., recently launched its first vessel to be built under contract. Hull No. 001—a 1,053-ton tug for an integrated tug-barge (ITB) system—is being built, along with four barges, for the State of Michigan. It was the first com- mercial launching at the 16- month-old yard. UPSCO used its 2,167-LT float- ing drydock for the launch. The drydock, which is equipped with removable wing walls for side transfers, was designed and built by the yard — its first newbuild- ing. The 120-foot-long tug, designed by the naval architectural firm of Breit & Garcia, New Orleans, La., is undergoing outfitting and completion of its superstructure while moored at UPSCO's dock. Four rail ferry barges for the ITB system are also being built by the yard, with the first barge scheduled for completion six months ahead of schedule. The tug has an automated en- gine room and is powered by two MAK 6M551, 4,000-hp turbo- charged diesel engines which drive Liaaen controllable-pitch propellers. The tug will propel one of the four 436-foot-long rail ferry barges in turn across Lake Michigan, while the remaining three barges are loaded and un- loaded in port. The tug and barges, ice-strengthened to per- mit year-round operation on the Great Lakes, will utilize a con- necting system and hydraulic pads manufactured under license from Bretagne ACB. The State of Michigan selected the ITB system to increase utili- zation of this cross-lake service and to eliminate a state rail sub- sidy which exceeds five million dollars annually. The state felt the versatility of the ITB would attract a variety of cargoes as would the unique shuttle sched- ule. The Hawaii Section of The So- ciety of Naval Architects and Marine Engineers held its first meeting of the 1981-82 season recently at the Cannon Club, on the Lanai, Fort Ruger, under the chairmanship of Dr. Manley St. Denis. A paper entitled "High-Speed Catamaran Hydrofoils" was de- livered by Rudy Choy, president of Aikane Corporation, one of Hawaii's largest commercial sail- ing operations. A member of the SNAME since 1964, he has been involved with catamaran con- struction and design since 1947. One of his major designs is the voyaging canoe Hokulea. Mr. Choy discussed the concept, design, and model testing of a proposed catamaran hydrofoil that was tested at the General Dynamics Convair tank in San Diego, Calif. It achieved a scale speed of 70 knots on the final day of testing, which was the desired goal. This design shows promise and warrants additional research and development. Other officers elected for the year include: vice chairman, Capt. Thomas Marnane; secretary- treasurer, John Biddulph; mem- bers, Executive Committee, Capt. Alfred Gallant, James Hollen- herg, Brian Trenhaile, and Dr. Frederick Munchmeyer. Southwest Marine Expands San Diego Offices Southwest Marine, Inc. has re- cently expanded its San Diego administrative offices. This is the beginning phase of plans to ren- ovate and add to the entire yard. "Our plans are to not only ex- pand with yards all along the West Coast, but to have the finest, most up-to-date yards in the country," stated Arthur Engel, president of Southwest Marine. The new addition includes com- puter and accounting facilities on the first floor. Management offices are located on the second floor, with a huge conference and meet- ing room on the third floor. Besides San Diego, Southwest Marine has ship repair yards in San Pedro and San Francisco. Oil-free Cutless® rubber bearings stop water pollution, conserve oil. In these days of fuel scarcity, leaky oil lubricated bearings waste energy and pollute our waterways. With Cutless water lubricated rubber bearings designed by Lucian Q. Moffitt, Inc., there's no oil seal to fail. No lube oil to leak out and pollute the waterways. Any water will lubricate the Cutless bearing ... fresh water, salt or sand-filled. Exclusive "Water Wedge" channels molded into a tough BFGoodrich rubber liner keeps plenty of lubricating water flowing through the Cutless bearing. Cutless bearings are available world- wide from yards and marine stores in a full range of shaft diameters and load capacities. Write us for engineering data. LUCIAN MOFFITT, INC.
