The high level of sophistication on the Leonard J. Cowley will be of significant benefit for the detection and prosecution of foreign vessels illegally fishing within Canada's 200 mile zone in the Northwest Atlantic. West Coast Manly Shipyards Delivers Fisheries Patrol Vessel Leonard J. Cowley A section of the bridge. The latest addition to the Canadi- an Department of Fisheries and Oceans' fisheries patrol fleet, the Leonard J. Cowley, is the largest and most sophisticated vessel of her type in Canada. Operating out of St. John's, Newfoundland, her major function will be the surveillance of the offshore fishing fleet within the Canadian 200-mile exclusive fisher- ies zone as far as 75° N and within Northwest Atlantic Fisheries Or- ganization waters outside the zone. This activity requires precise nav- igation, excellent boarding facilities and superior communications as well as seakindliness in all weathers, substantial capability in ice and he- licopter facilities. All of these re- quirements are fully met. The vessel is also well equipped for search and rescue response. Built by West Coast Manly Ship- yards of Vancouver, B.C., a division of Rivtow Industries Limited, the ship's principal particulars are: gross tonnage, 2,244; displacement, 2,086 tons; overall length, 72 meters (about 236 feet); maximum beam, 14 meters (about 46 feet); and mean draft, 4.5 meters (about 14% feet). Main engines are two 12-cylinder Polar Nohab F312A diesels, and propulsion is 3,120 kw, single-screw, variable pitch. She is classified Lloyd's 100 A.I., Ice Class 1*, LMC. Designed by Cleaver and Wal- kingshaw of Vancouver, the Leon- ard J. Cowley has numerous innova- tive features, representing the lead- ing edge of technology in navigation systems, communications, machin- ery, electrical monitoring and con- trol, accommodation, helicopter fa- cilities, maneuvering, wheelhouse design and boarding facilities. The navigation system consists of two Sperry true motion MK-340 ra- dars, one X Band (with a C-P anten- na) and one S Band, that are fully interswitchable, combined with a CAS II ARPA, with the Channel Navigation Option. This system in turn is linked to a Sperry/TRAC IVB Qubit fully integrated naviga- tion computer that is capable of fil- tering sensor information for maxi- mum probability computations, us- ing the INSQUA technique. This system includes high resolution color graphics, twin disc drives, a plotter, printer and a remote dis- play. The sensors include twin Sper- ry Gyros (MK227 and MK37), Mag- navox 1107 RS dual channel SATNAV, INTERNAV LC 720 Lo- ran C receiver, and a Raytheon DSN 450 dual axis doppler log.
