Winches for a new fishing vessel Karearea
PURPOSE-BUILT SCAMPI CATCHER
When Whangarei company Penwarden Holdings was looking to build a modern trawler to fish for scampi, they went to Oceantech, a ship designer with bases in both Australia and New Zealand.
The result is the Whangarei-registered Karearea, the latest Oceantech fishing vessel design and the only purpose-designed scampi trawler fishing in New Zealand waters. Many of the design cues were taken from Penwarden’s existing vessel Bilyara which has served the company well, keeping the overall arrangement, but with a need to incorporate modern features and greater capacity.
Particular attention was paid to optimising fuel capacity, at 110,140 litres, to provide greater endurance, giving Karearea a very full hull. While the majority of Oceantech’s recent fishing vessel designs have featured a plumb bow, this time the option was taken to go instead for a bulbous bow hull form.
A further feature is that Karearea has articulated stabilisers to aid seakeeping, and these are becoming a common feature in Oceantech’s trawler designs.
Karearea was built in Australia, where after a gap of a decade in building fishing vessels, MG Engineering in Adelaide took on the construction of the steel-hulled trawler which has an overall length of 25 metres with an 8 metre beam and a 3.50 metre draught.
The aft engine room is home to a set of Caterpillars, with a C7.1 gensets and a 1000hp C32 main engine driving a VP10 propeller via a CPGD50 reduction gearbox, both of which are from Hundested, providing a top speed on trials of 10.50 knots, a respectable cruising speed of 9.50 knots and a 16-tonne bollard pull. The 55 cubic metre refrigerated fish room is located forward of the engine space.
The Neumann Equipment trawl winch is located aft of the wheelhouse, overlooked by the trawl control position, with the trawl winch flanked by a pair of codend winches below a substantial gantry behind the wheelhouse. An additional swinging gantry is fitted at deck level, over the large-capacity reception hopper.
The wheelhouse is fitted with a range of hardware supplied by Dunedin company Navcom Electronics, including a WASSP F3i multibeam sounder and a Furuno FCV 1900 as the main fishfinders. There’s plenty of Furuno kit on board, including a FAR 1515B 12kW radar, GPS receiver, weatherfax, NavPilot 700 autopilot, satellite compass and AIS set.
Communications are handled by the pair of Icom SSB sets, Saylor satcom and Iridium Extream. Plotter are SeaPlot and MaxSea Time Zero sets, and Marport supplied the trawl monitoring sensors.
Catches are dropped into the reception hopper at the stern and are carried forward to the processing area via a sorting belt.
Accommodation for the crew of eight is located forward at main deck level, with a pair of two-berth cabins and a four-berth cabin grouped around the spacious galley and mess area.
