Golden Shore’s new rig of six-aside scallop dredges was manufactured by Kirkcudbright specialists Deeside Marine Ltd.
The scallop gear is towed by 100 fathoms of 20mm-diameter compact steel core wire supplied by Jim Hamilton of Kilkeel.
Michael Watt of Gamrie Bay Trawls supplied Golden Shore’s 12-fathom queenie net. Rigged on 12in discs, the queenie trawl is effectively towed directly from a set of 6ft 3in doors manufactured by Kilkeel Steel Products. 150 fathoms of 16mm-diameter wires, usually spooled on top of the heavier scallop dredge wire, are used for queenie trawling.
Arranging the accommodation cabin on the main deck created more space below it. This has been fully utilised by the designer and boatbuilder to create a spacious and extremely well laid out forward engineroom, in which all machinery is easily accessible for all levels of service in years to come. The main access down to the engine room is just off the main deck on the starboard side. Secondary access is from inside the accommodation space.

Golden Shore is powered by a Cummins QSM11 engine that develops 220kW @ 1800rpm and is coupled to a ZF W350 5.99:1 reduction gearbox to turn a 1600mm-diameter 4-bladed Teinbridge propeller in a matching fixed nozzle. This centreline combination returned a top speed of nine knots when Golden Shore ran engine trials of the coast of Co Donegal, since when the main engine has delivered a highly economical fuel consumption of around 30 litres per hour when running at 1500rpm and steaming at eight knots. This impressive level of fuel economy means that together with the two auxiliary engines, one of which runs continuously, Golden Shore uses no more fuel than her single-engined predecessor Lynn Marie.
Mooney Boats machined the 110mm stainless steel propeller shaft and stern tube in-house. The intermediate shaft is also stainless steel, and is joined to the tail shaft with a coupling which is accessed through a hatch in the fish room. A Cooper bearing is fitted just forward of the coupling to take up the weight and another at the engine room bulkhead to carry the weight of the shaft.
Two Jabsco 1½ inch 24-volt clutched fire and bilge pumps are driven off the front end of the main engine. Each pump has been piped so either one can be used for bilge suction or deck wash duties, or the two pumps can also be run simultaneously to get extra water flow when required.
The main auxiliary engine is a Mitsubishi 6D16-TE2 (106kW @1500rpm), supplied by DR Diesel of Kilkeel. This unit drives twin pumps for the vessel’s main hydraulic system through a Twin Disc clutch, mounted on the bellhousing, together with a 40kW generator at the front end.

A similarly-rated electrical generator is driven continually by a Mitsubishi SQ4 auxiliary, supplied by Ashvale Engineering, positioned on the port side of the engineroom. The main and two auxiliary engines are box cooled by Blockland coolers supplied by the yard.
Rapp Marine supplied Golden Shore’s hydraulic system, which was installed and piped by the boatyards before being commissioned by Rapp Marine, together with the deck machinery.
A hydraulic pump retrieve system is driven from a PTO on the gearbox. This pump is fitted with an air ram and electric solenoid, enabling the skipper to operate it from the wheelhouse. The retrieval pump is also used to drive either the twin catch conveyors when the crew are sorting the contents of the scallop dredges, or the queenie riddle, thereby eliminating the need to run the hydraulic engine after the gear has been shot back.
Twin deep wing tanks positioned against the engineroom aft bulkhead enable Golden Shore to carry up to 11,400 litres of fuel. A 3,700 litre capacity freshwater tank is located in the bulbous bow. All the wiring on Golden Shore was completed to an extremely high standard by Mooney Boats’ own electricians.
Five bunks are arranged in the accommodation cabin on the portside of the deck casing.
All external wiring is run on stainless steel cable trays and clipped neatly. The main distribution boards are fitted in the engine room port side, with subdistribution boards fitted in the wheelhouse.
The main electric system is a 3-phase/220-volt system which can be powered from either of the auxiliary engines. A 24-volt system is also fitted for emergency lighting and navigational equipment. LED lighting is used throughout to reduce energy consumption. Two banks of service and emergency batteries are fitted, backed up by a Victor Skyla-I 24/100 main and TG 24/50 backup chargers.
Wills Ridley steering gear is fitted.
On completion of all structural work on the vessel, Corrosive Solutions and Inspection Services Ltd (CSIS) painted the Golden Shore with a Jotun paint system supplied by the yard’s chandlery store.
