Burton Delivers 224-Ft. Seiner,

Second Of Seven For Van Camp

Burton Shipyard, Inc., Port Arthur, Texas, recently delivered the 224-foot tuna vessel

Patrician. The steel-hulled tuna purse seiner is the second of a seven-vessel contract awarded to Burton by Van Camp Sea Food

Co., a division of Ralston Purina Co., and is jointly owned by Van Camp and Capt.

Manuel Vargas. The purse seiner will oper- ate primarily with the Pacific fleet, docked in San Diego, Calif., and will fish the Pacific

Ocean for skipjack and yellowfin tuna.

The Patrician 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 Patrician will travel through the Pan- ama Canal and into the Pacific, fishing the eastern Pacific waters before being intro- duced to the San Diego tuna fishing com- munity.

The new tuna seiner is propelled by a turbocharged EMD marine diesel engine de- veloping 3,600 shp at 900 rpm. The 20- cylinder engine drives a 132-inch-diameter, five-blade stainless-steel propeller, built by

Avondale, through a Falk 5.033:1 reduction/ reversing gear. Shaft speed development is rated at 179 rpm. Auxiliary power for the vessel is provided by three Caterpillar D-353

TA diesels with 300-kw Kato brushless gen- erators. The ship's bow thruster is a Bird

Johnson model 10/35/FP with direct Cater- pillar drive.

A passive stabilizer has been incorporated into the hull structure and was engineered by John J. McMullen Associates. Fishing gear and hydraulic equipment are by Marco and include a model WS444 purse seine winch and the Puretic power block model

B56-61990-185. A Whaley model B-102-H hydraulic ring stripper is also provided.

The ammonia systems utilize Vilter com- ponents which were subcontracted by Re- frigeration Systems of New Orleans, La.

Navigational aid and communications equipment, provided and installed by Marine

Electric of San Diego, Calif., 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 assort- ment 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 Patrician 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 at a time before bringing her payload of tuna back to San

Diego.

Burton expects delivery of the third tuna vessel, the Deolinda, to be in early 1982.

Delivery of the seventh boat will be accom- plished in 1983.

Second Wind-Assisted Diesel

Propelled Ship Building In Japan

A second coastal tanker designed for wind- assisted diesel propulsion will be delivered soon by Imamura Shipbuilding, Kure, Japan, to Aitoku Co., owner of the first such com- mercial sailing vessel.

The second ship, the Aitoku Maru, will take Japanese sail research one stage fur- ther and differs in one crucial respect from her predecessor. The first ship, Shin Aitoku

Maru, was built with her two masts and sails in place, and performance results could not be compared with any reference data for that ship.

The Aitoku Maru has been built initially as a normal power-driven vessel so that full data on the bare vessel can be obtained be- fore the sails are fitted later.

In hull design, the Aitoku Maru is sim- ilar to Shin Aitoku Maru. Propulsion ma- chinery, hower, will be a Daihatsu medium- speed 60SMA-32F diesel with reduction gear rather than the earlier ship's derated and slow-speed Hanshin diesel engine.

Other changes are a different arrange- ment of internal hull divisions and a slightly smaller area for the sails when these are eventually fitted.

Those are two major advantages to consider about the

Levco 360° 5-ton revolving crane. In addition, it's easy to ser- vice by your own mechanics and most parts are galvanized or inorganic zinc coated for complete protection against corrosion.

The Levco crane is also available with several options: 2 air powered models (manual or power swing) and 2 hydraulic models (diesel or electric). And although the standard boom is 30', booms up to 50' can be ordered.

As if that weren't enough, our starting price is only $35,000.^
