With 4,989 kilometers of Atlantic coastline, Argentina looks to commercial fishing as an important contributor to the Argentinian economy. The promotion of the maritime resources is dependent on quality boats capable of delivering quality product.    This spring just such a vessel joined the Argentine trawler fleet. The 20.8 by 6.6-meter FV Don Franco was designed and built by the Contessi Shipyard at Mar del Plata, Argentina’s largest fishing port 400 kilometers south of Buenos Aires. Owned by the Galeano family, the new vessel is classed by RINA and will replace their older boat the Galme I. The new trawler will make just under 10 knots with a 600 HP, six-cyliner Cummins KTA19-M main engine. At 1,800 RPM the engine will turn a propeller in a nozzle through a ZF 1800 marine geat with a 6:1 ratio. The nozzle will assure good power for towing a midwater trawl. The boat is also capable of being rigged for purse seining. The two gear types will allow for the catching of a wide variety of species including, besugo (sea bream), merluza (hake), bonito and anchovita.   Tankage in the 3.2-meter deep hull includes 20,500 liters of fuel and 4,000 liters of water. The vessel’s hold is a healthy 87 cubic meters. Accommodation is provided for up to ten fishermen. Auxiliaries for powering generators and hydraulics include a Cummins 6 CTA8.3G and a 4BT3.9-iiter Cummins.   


Long Lines for a Purse Seiner

Purse seining is well known as one of the most effective technologies for demersal fisheries. Today many nations support extensive fleets of 20 to 30-meter wood, steel, fiberglass or aluminum vessels working with nets that range of 500 to 1000 meters in length. Throughout Malaysia and Thailand, even in the wooden boat fleet, these vessels are typically equipped with sonar and Puretic-style hydraulic power-blocks for hauling back the nets.


Box: Generations on An Alaskan Limit Seiner

Petersburg, Alaska has been known since its founding as the home of good fishermen and fine boats. One of the earliest limitations on the commercial salmon fishery was the limiting of Alaskan seine boats to 58 ft. Over time, the Alaska limit seiner evolved to one of the truly classic fishboats of the world. With its high bulwarks over a plum bow stem and a full body flowing with a clean shear aft to a broad timbered stern

For many years Alaskan salmon purse seiners have been limited to a length of 58 ft. This led to the development of some beautiful and relatively beamy wooden boats in the 1950s. In the intervening decades designers have fine-tuned the 58 ft design to add beam and depth. An example of this is being built at Westman Marine in Blaine Washington to a design by Hockema & Whalen Associates Inc. of Seattle and Bellingham Washington
