Rados-Designed 2,000-Ton Capacity Seiner To Be Constructed For Tuna Fleet By Peterson Artist's conception of the 3,500-ton tuna seiner Margaret L. which displays a yacht- like profile. The crow's nest, 92 feet above the waterline, will be reached by an elevator installed in the hollow mainmast rising from the bridge structure. The world's largest super seiner, the Margaret L., displacing 3,500 tons and with a load capacity of 2,000 tons, has been designed by Rados Western Corporation of San Pedro, Calif., and will be built for a California group by Peterson Builders, Inc., of Sturgeon Bay, Wis. The yach't-like vessel, capable of fishing for tuna anywhere in the world, will have a cruising range of about 4,000 miles at a fully-load- ed speed of 17 knots. Of all-steel construction, the hull length is 262 feet with a waterline of 240 feet at design draft of nearly 19 feet. To help assure continuation of fishing operations despite difficult weather conditions at sea, a special stabilizer system designed by Flume Stabilization Systems, Inc., will be installed. The system was first incorporated in previous Ra- dos Western vessel designs. Robert Rados, president of Ra- dos Western, a wholly owned sub- sidiary of Western Gear Corpora- tion, Lynwood, Calif., said main propulsion machinery of the Mar- garet L. includes two Colt Indus- tries Fairbanks Morse diesel en- gines, each developing 3,000 bhp at 750 rpm, coupled to two 125- inch diameter propellers through Western Gear 360 PCMR seamaster reverse reduction gear assemblies. Two Caterpillar 400-kw main generator sets and one Caterpillar 250-kw standby set will provide electrical power for the extensive array of shipboard equipment. Messing, berthing and galley ac- commodations, planned for long sea cruises, are provided for a com- plement of 18 crewmen. The crowds nest, 92 feet above the waterline, will be reached by an elevator installed in the hollow mainmast rising from the bridge structure. Extensive refrigeration equip- ment will be provided by the Vilter Manufacturing Corporation; the huge seine winch and other deck machinery will be provided by the Marine Construction Company; and the radar installation will be Sperry Rand Corporation equip- ment. The Margaret L., home porting in Puerto Rico, will stream a one- mile-long purse seine to fill its 20 brine wells with a capacity of 86,000 cubic feet. At the recently quoted price of $420 a ton for yel- low-fin tuna, a full load catch would be valued at about $840,000. The new seiner, owned by An- drew J. Lococo and Associates, of Hawthorne, Calif., and bearing the name of Mr. Lococo's wife, is en- gineered to meet demands for fast unloading and turnaround sched- ules by equipment which permits simultaneous discharge of frozen fish from port and starboard wells to the upper deck, both forward and aft, using a heavy brine solu- tion with increased "flow and pres- sure" systems. From the deck, the catch is routed overboard on chutes to cannery shore facilities. Expected to be completed in Oc- tober 1972, the Margaret L. will join sister vessels of the far-roving San Pedro tuna fleet, many of which now fish along the West African coast and off-load at can- neries in Puerto Rico. Big seiners of the fleet which have been de- signed and engineered by Rados Western and built by the San Di- ego Marine Construction Company include the Quo Vadis, Jacquelina A., Sea Quest, City of Lisbon, An- tonia C., Mary S., Francis Ann, and Adventurous. Pickands, Mather Signs First Construction Pact In New MarAd Program The Maritime Administration has disclosed that Pickands, Mather & Co. has become the first operator to sign an interim capital construction fund agreement with MarAd under the new program to rebuild the mer- chant marine. The agreement, which will ulti- mately be replaced by a permanent one once the Treasury completes its regulations, will enable the Great Lakes bulk carrier operator to set aside funds tax free for new ship construction. That privilege has just been open- ed to nonsubsidized liner operators by the administration's new long- range maritime promotional program. Direct Control of Engines From The Bridge Throttle Control and Engine Order Telegraph are now combined in one compact Henschel unit to simplify their use and to save console space. Less expensive than two separate units the new control is also easier to install and to maintain. Designed for easy reading from any angle, its smart appearance is matched only by the convenience of its single-control utility. Also adaptable to pedestal mounting.
