Burton Shipyard, Inc. of Port Arthur, Texas, recently delivered the 224-foot tuna vessel Lady Marion. The steel-hulled tuna purse seiner is the sixth of a seven-vessel contract awarded to Burton by Van Camp Sea Food Co., a division of Ralston Purina Co. The purse seiner will operate primarily with the Pacific fleet, docked in San Diego, Calif., and will fish for skipjack and yellowfin tuna.

The Lady Marion measures 42 feet wide, with an 18-foot draft, and cruises at 16 knots. The vessel is designed to operate with a crew of 21, and is capable of carrying a 1,200-short-ton payload of frozen tuna.

The vessel will travel through the Panama Canal to San Diego, fishing the eastern Pacific waters after being introduced to the San Diego tuna fishing community. The new tuna seiner is propelled by a turbocharged EMD marine diesel engine developing 3,600 shp at 900 rpm. The 20- cy'iinder engine drives a 132-inchdiameter, f i v e - b l a d e stainlesssteel propeller, built by Avondale, through a Falk 5.033 :i reduction reversing gear. Shaft speed development is rated at 179 rpm.

Auxiliary power is provided by three Caterpillar D-353 TA dieseis with 300-kw Kato brushless generators. The ship's bow thruster is a Bird-Johnson model 10 ' 35 FP with direct Caterpillar drive.

A passive stabilizer has been incorporated into the hull structure and was engineered by John J. McMuIlen Associates. Fishing gear and hydraulic equipment are by Marco and include a model WS444 pur.se seine winch and the Puretic power block model B56-61990-185. A Whaley model B-102-K hydraulic ring stripper is also provided.

The ammonia systems utilize Vilter components which were subcontracted by Refrigeration Systems of New Orleans, La.

Navigational aid and communications equipment, provided and installed by Marine Electric of San Diego, consists of a Magnavox 1102 SatNav receiver, Furuno FRJ-100 and DRA-1064 radars, FE812 depth sounder, FDK-245 ADF and scanning sonar. Other nav com gear includes Sperry MK 37 gyrocompasses, gyropilot, Furuno weather recorder model FAX 143, and a broad assortment of radio communications equipment. A helicopter rides on the pad located on the wheelhouse top. A private stateroom is provided for the pilot and his mechanic, who also have a workroom on the boat deck.

Five outboard chase boats are stored on both the boat deck and the upper deck. The diesel-powered skiffs were purchased from Mauricio & Sons of San Diego. The Lady Marion is also fitted with a Red Fox model 750M biological treatment sanitation system. The vessel is equipped to stay at sea for as long as three months before bringing her payload of tuna back to San Diego.

Burton expects delivery of the seventh tuna vessel, the Judith Carol, to be in early 1983. The purse seiner was designed by Rados International of San Pedro.
