Lunar Sea

After looking around for a replacement ‘Lunar Sea’s owners Wayne and Jack Davies finally settled on ASCI because of the quality of the workmanship, and the style and reputation of her Peter James designed predecessors in the Gulf fishery, combined with a very attractive price package. The also liked the flexibility to add their own personal touch to the vessel, customising her for their own specific requirements.

A 50 horsepower hydraulic bow thruster from Wesmar. The trawler’s sea keeping qualities and economy are all enhanced by the now trademark bulbous bow, and her lines are clean, simple and workmanlike in every way.

‘Lunar Sea’ returned to Port Lincoln for some final finishing touches including the installation of the Haldan grading machine and hopper. This machine allows the prawns to be sorted in up to seven sizes, and sits forward of the two sorting tables allowing adequate deck space for the working crew.

Loaded, she carries 20 tonnes of frozen product with the air blast snap freezer taking the 180 ten kilogram cartons down to -40ºC, well within DPI standards.

The refrigeration is by C.M. Heithersay Industries, and has two Bitzer rotary screw compressors with oil coolant on R507 refrigerant.

These compressors are said to operate more favourably than the reciprocating type at low temperatures and are returning excellent performance. The pipe work is all steel, and the low temperature evaporators are fitted with Danfos Electronic TX valves.

The engine room layout is well thought out, brightly lit and appearing more roomy than is traditional in the usual trawler.

A single Caterpillar 3408B marine diesel engine provides the propulsion. The 365hp, eight cylinder engine powers the vessel via a 6:1 reduction Twin Disc MG 516 gearbox to the 1.8metre diameter Veem propeller which is housed in a nozzle for greater efficiency. On sea trials she easily achieved 10 knots.

The main engine and Caterpillar-badged Perkins auxiliaries, (two 108kVA gensets) and the 114kW hydraulic drive, are all provided by Caterpillar.

Her tanks hold 50 tonnes of fuel to give adequate range for the intended fishery.

The roomy wheelhouse has excellent all-round visibility, and easy access to the single console located on the deck directly behind it. The console is designed for single-handed operation of all the deck machinery.

Once again, the winches and hydraulic installations are all from EBM Engineering. Fully air conditioned, her accommodation is bright and attractively detailed with high quality Naytah woodwork.

The crew of four are comfortably housed in three two-berth cabins forward of the mess which is fully equipped with a VCR and television and superior sound system as well as a comfortable seating area.
