The South Australian Fisheries Department’s decision to extend the allowable length for Spencer Gulf prawn trawlers from 19.8 to 22.0 metres has brought additional work to Adelaide Ship Construction International Pty Ltd at Port Adelaide.
Taking advantage of the new rule, marine architect Peter James designed a trawler for Adelaide Ship construction International and two were ordered from the drawing board.
The first, ‘Kali II’, was launched in the late June by the owner’s wife, Mrs Aka Gobin and is operating out of Port Lincoln, the vessel’s home port. The second is due to be launched around the end of the year.
‘Kali II’ was designed to the requirements of the owners, AJKA Pty Ltd of Port Lincoln.
Propulsion is by a single Caterpillar diesel Type 3408B with a nominal rating of 272kW at 1,800rpm driving a 1,800mm Veem propeller through a Twin Disc MG 516 gearbox of 6:1 reduction.
Design speed of the vessel is 10 knots but the builders say this was exceeded in trials, which also showed her good handling qualities.
Auxiliary power is provided by a Caterpillar 3304B driving an 85kW alternator with a six-cylinder Perkins and 15kW alternator as stand-by. Another Perkins diesel drives the hydraulic power pack and pumping systems. All engines are keel cooled.
The well-equipped wheelhouse is situated on the forcastle deck immediately ahead of the control station for the trawl winches, and the twin funnels.
In the forecastle, ahead of the enclosed processing room, are spacious crew quarters. Below the main deck are the holding room which can hold 30 tons of prawns at -40ºC and the snap freezer to hold 100@10kg cartons.
Aft of the engine room two brine tanks with a combined capacity of 17 tonnes are separated by a tunnel leading to the steering gear.
More than 40 tonnes of fuel are carried in tanks under the holding room and wing tanks in the engine room and the after peak, while 13 tonnes of fresh water is held in a tank forward of the holding room.
