A repeat order is always the sign of a satisfied customer and the fact that twin-rig trawler Jacqueline Anne FR-243 is the fourth new vessel in only twelve years for Adam Tait and his sons Adam and Johnny speaks for itself, reports Dave Moore.
Jacqueline Anne is expected to work six-day trips on North Sea grounds, landing catches in Fraserburgh, with nephrops catches processed by the Scottish Fishermen’s Organisation. Adam Tait and his sons sail as skippers on a rotational basis across Jacqueline Anne and their other trawler, Rebecca FR-143, which was delivered by the same builder in 2016.
An all-Macduff build, Jacqueline Anne has a 24.50 metre overall length with a 7.60 metre beam and a moulded depth of 4.30 metres. During the design process CFD technology was used at an early stage to measure the resistance of the new hull against previous designs and to identify areas where further improvements could be made. The hull form was finalised and faired virtually by Macduff Ship Design who then produced a detailed set of kit construction plans. The steel kit was cut in house by Macduff Profilers, and the build was split between the yard’s two sites, with steel modules being fabricated in Macduff and shipped to Buckie for assembly, engineering and fitting out.
Jacqueline Anne’s layout is largely similar to the yard’s other recent new deliveries, with cabins, engine room, fish hold and a large freshwater tank forward of the collision bulkhead be. Above deck are the aft shelter, galley, mess and side passage area, catch-handling area and the winch room in the forward section.
The working deck has been customised to suit the owner’s requirements with a dry locker, hold unloading hatch, fishroom access stairwell and refrigeration plant room all to the port side, creating a large hatch-free fish processing area on the centreline and the standard hopper and tray sorting arrangement on the starboard side. The galley and mess area extend the full length of the deckhouse, which also includes a shower and washroom placed centrally.
The first new Scottish twin-rigger to be fitted with a variable pitch propulsion system, Jacqueline Anne has a 2700mm diameter controllable pitch propeller, supplied by Helseth A/S, driven by a Kumera K-CPP-450 two-step gearbox with 12.3:1 reduction.Propulsion power is provided by a 559kW Caterpillar C32 main engine supplied by Finning Power Systems, and freshwater cooled via a Blokland box cooler. The flexibility of the C32 main engine which allows for full power to be developed between 1600-1800 rpm along with unlimited control of pitch inherent with CPP systems provides a high level of control. This was demonstrated by Jacqueline Anne’s excellent performance during low-speed operations such as manoeuvring in the harbour, while also being able to optimise the engine speed and propeller pitch combinations for both trawling and steaming to achieve maximum efficiency.
Having had experience of the advantages of a triple rudder on the previous Jacqueline Anne and Rebecca, the owners wanted the same installation for the newbuild. Positioned behind the nozzle, the triple rudder means that relatively small helm adjustments are needed to steer, with the effects particularly noticeable when towing across the tide, and there is minimal power loss when turning.
Primary hydraulic power is provided by two Danfoss load sensing hydraulic pumps driven from the Kumera gearbox. A back-up hydraulic net-retrieve system is powered by two 45kW electrically driven pump sets, and capable of running simultaneously when both Caterpiller gensets are in use.
Electrical power comes from the two 118ekW Caterpillar C7.1 generator sets which are set up to be run simultaneously if required to power both the general systems and both the electrically driven hydraulic pumps sets. The harbour set is a 33kVa Beta Marine unit contained within a silenced acoustic housing to keep noise to a minimum when alongside.
Macduff Shipyards delivered Jacqueline Anne’s deck machinery and load-sensing hydraulic system, with three split trawl winches located in the forward winch room, placed in a triangular configuration. With a 15-tonne core pull, the winches are fitted with two-speed Hägglunds Drives motors for faster hauling and shooting. The middle wire runs under the wheelhouse floor before leading upwards to a hanging block mounted on the underside of the base on which the powerblock crane is mounted, directly above a secure track for the safe storage of the middle roller.
All of the deck machinery aft is operated from a control panel built into the fishing console in the wheelhouse, placed to offer a clear view of the trawl doors and clump coming up to the blocks.
Two 2×12-tonne split net drums are arranged side by side on the non-watertight wooden-decked quarter, in line with the transom shooting and hauling hatches, the lower edges of which are fitted with free-turning large-diameter rollers. Two sets of 2×8-tonne split sweep line winches are mounted on the shelterdeck in line with openings across the transom that extend down to the shelterdeck.
Thistle Marine Ltd. supplied the MKB13 kinked boom crane fitted with a slew ring base and 24 inch powerblock, mounted on the centre of the trawl gantry.
Adam Tait went to local netmaker Faithlie Trawls for two complete sets of gear for Jacqueline Anne. These are a set of triple mouth letterbox style 200ft trawls rigged on 6-, 8- and 10-inch discs, while for hard ground 180ft Off-Roader” prawn scraper nets rigged on 8- and 10-inch discs are used. Jacqueline Anne uses 50 fathoms of 34mm diameter 4-strand combination warp and 10 fathoms of 20mm diameter wire rubber legs to connect the twin rig trawls to a 1200kg roller clump and a set of Thyborøn Type 11 doors. Caley Fisheries supplied all Jacqueline Anne’s trawl chandlery, including three sets of 300 fathoms of 22mm diameter fibre core trawl wire.
A set of Simrad PX twin rig double distance net monitoring system monitors the doors and clump, providing a rolling update of the clump’s position in relation to the trawl doors, while also providing twin net spread and pitch/roll measurement, while the clump sensor provides depth and water temperature measurement.
Woodsons supplied the electronics in Jacqueline Anne’s wheelhouse, focused around the central console and including a quad view video wall of three 55-inch 4K bridge monitors arranged across the front of the wheelhouse, on which all modes of fishing and navigation operations are shown in customised screen displays. Five Neovo X24 wide screen displays are also fitted. An iPad app enables the skippers to select the preferred screen arrangement.
The sounder is a JRC JFC-180BB digital broadband colour unit operating a combination of four user set frequencies between 38kHz and 200kHz as well as providing ground discrimination data output interfaced to the Olex plotter. Positioning data from the GP39 GPS receivers is interfaced to an Olex 3D seabed mapping system and a Sodena Easywin plotting system, which support tidal data, AIS and ARPA tracking. Woodsons also installed a comprehensive CCTV system deploying 25 HD cameras.
