Canada, a member of the GenStar Limited group of companies, formerly Soge-mines Limited of Montreal, has an-nounced that it will build another barge of the same type capable of carrying almost twice the 11.000-ton load of its present log carrier. It will be named Island Forester. The new barge will carry more than 20.000 tons of logs, equivalent to over 4 million board feet. The announcement of its construction heralds a new $7-millioti tug and barge construction program, fol-lowing hard on the heels of a $4-million program launched in 1965.

South San Fran-cisco. Calif. 94080. Capt. Reese To Head Eastern Operations For Pacific Maritime William A. Keefe III, managing director and chief engineer of Pa-cific Maritime Consultants, Inc.. has announced the appointment of Capt. John D. Reese Jr., USN (ret.) as director. Eastern Operations, for the firm. PACMARC, 4976 Marlborough Drive, San Diego, Calif., is a con-sulting firm specializing in marine engineering, naval architecture and naval design projects. The firm also performs hull and machinery surveys and plans marine salvage operations. The Eastern Operations, which will be headed by Captain Reese, has its offices at 240 Glen Avenue SAY., Vienna, Va. The entire power requirements for the Robin Rose were designed and supplied by Stewart Stevenson. The boat can push three 200-foot light barges at 10V4 miles per hour and 8 miles per hour loaded. A unique towboat powered by a new GM Detroit Diesel engine that combines power with versatility has been placed in Gulf Coast Intra-coastal Canal service by Par-ker Brothers Company in coopera-tion with Stewart & Stevenson Services. Inc. The craft, officially named Robin Rose, was built at the Parker Brothers Shipyard, Houston. The entire power requirements were de-signed and supplied by Stewart & Stevenson, the world's largest dis-tributors of diesel engines. A spokesman for Parker Broth-ers reported the boat has performed "extremely well" since it was put in service earlv last November. The new 12Y-149 GM Detroit Diesel engines which power the boat com-bine compact durability, minimum weight and maximum economy and still meet the increasing demand for higher horsepower. The Robin Rose engines are rated up to 800 hp. I he boat can push three 200-foot light barges at 10y2 miles per hour and eight miles per hour load-ed. Robin Rose is operating be-tween Houston and Corpus Christi and makes a round trip between these two cities in approximately 50 hours. The GM Detroit Diesel engines in the boat turn four-bladed pro-pellers that are 72 inches in diam-eter and have a 48-inch pitch. The boat is also equipped with a Lufkin ROS 1612 marine reverse reduction gear with a 5.4:1 ratio. For her auxiliary power needs, the boat has Stewart & Stevenson 36 D 40 generator sets. These sets are powered by 371 GM Detroit Diesel engines complete with Stew-art & Stevenson switch gears. The Robin Rose is 75 feet long. 26 feet wide and 8 feet deep. She is also equipped with four flanking rudders, two for each wheel. These rudders allow for positive control of the vessel and make it possible for the boat to turn sharply and maintain control of its barges in rough weather. 58 Maritime Reporter/Engineering News
