MFV ‘COPIOUS’ LK 985 – 24.9m Demersal Trawler for 60 North Fishing


Macduff Ship Design are pleased to announce the completion and handover of MFV ‘Copious’ LK 985, a new 24.9 m fishing vessel for 60 North Fishing company of Shetland.  The vessel is the first of a pair of sister vessels for the company and was built in Croatia by Tehnomont shipyard to a full design package supplied by Macduff Ship Design.  The vessel completed her delivery trip to Shetland, through the Mediterranean, up the west coast of Portugal, Spain and Ireland, arriving in Shetland on the morning of the 14th January just in time for the islands fire festival Up Helly Aa.  The second vessel to be named ‘Prolific’ is set to be delivered later in the year.

Macduff Ship design were first contacted by Mark Anderson, who heads 60 North Fishing with partners, Andrew White, Ryan Arthur and fish selling agent LHD, 5 years ago to develop a bespoke new design. Mark had a clear idea of what he wanted the vessel to achieve and some of the key design factors that needed to be considered. In close co-operation with Mark a General Arrangement plan and Specification were produced. These were sent to a number of yards for a tendering process. Macduff Ship Design assisted Mark and his 60 North Fishing partners during this process through to final yard selection.

Once Tehnomont Shipyard were selected as builder in 2020, Macduff Ship Design set about developing hull form, detailed construction and outfitting plans. One of the first key decisions was sizing the propeller. Larger CP propellers can have notable efficiency savings hence the largest propeller that could fit was to be selected. The aft end of the hull was developed to ensure this was possible with a 3.0m Finnoy propeller chosen. This was fitted inside a Kort nozzle with triple rudder arrangement for improved manoeuvrability.

In recent years Macduff Ship Design have been involved in tank and CFD testing of several vessels, and have developed an advanced understanding on how the hull form can influence both vessel resistance and seakeeping. This knowledge was applied to the hull of the Copious to ensure the crew would have a vessel that could handle the unpredictable and often times rough seas in their fishing area but would also have optimum efficiency to minimise fuel consumption.

The amount of, and layout of, deck machinery, fishing gear and fish processing equipment was of high importance to Mark. The vessel needed to readily be able to swap between single net trawling, twin rigging and pair trawling with all equipment needed for these three operations to be carried onboard. The arrangement of the deck machinery was developed collaboratively with Mark, with a number of innovative ideas integrated into the design. This was both to improve the safety, and efficiency of the vessels fishing operations.

Catch quality and value was a high priority on the vessel and although designed with the ability for 10 day trips it is expected that the vessel is likely to focus on shorter trips.  In order to maximise the quality of the landed fish there has been a high importance placed on the way the fish is handled once caught, with care taken in the design of all of the systems, with particular attention being paid to the processing equipment supplied by JJ measuring systems.  Once the fish is landed through the aft cod end hatch into the hopper it is immediately cooled with a water spraying and slush ice system.  After passing through the gutting area the fish are sorted into one of two 6 compartment cylindrical, selector/coolers supplied by Danish firm Carsoe to a design from Jim Johnson of JJ measuring systems.  Each segment can be emptied individually in any order to suit the optimal fish cooling. Once cooled the fish are transported by conveyor to the fish access hatch and into the hold to a portable table with 4 workstations.  The fish are graded, weighed and boxed with freshwater and flake ice before being stored in the 1100 box capacity hold.  The hold also contains 2 x 2.5 T capacity Buus slush ice tanks which work in conjunction with the 2 x 4.5 T per day ice machines on main deck.  The water for the system is supplied from the onboard fresh water tanks and a 2 T per day Alfa Laval freshwater desalinator fitted in the engine room.

The vessel is fitted with a Mitsubishi V12 S12R main engine rated 588Kw at 1400rpm and this is coupled to a Finnoy FK50 11.3:1 gearbox.  This drives a Finnoy 3000mm diameter controllable pitch propeller fitted in a nozzle supplied by Kort Propulsion.  The vessel is fitted with a triple rudder and bow thruster also supplied by Kort propulsion, which give the vessel excellent manoeuvrability for fishing day to day operations.

The deck machinery package supplied by Rapp MacGregor is driven by 3 hydraulic pumps driven from power take offs on the Finnoy gearbox and electric towing pumps.  The fishing equipment consists of 3 x 14 T trawl winches arranged under the focsle forward.  They can carry 1100 fathoms of 22mm wire but are set up with 700 fathoms of Brunton Shaw warps supplied by LHD.  The winches are linked to a scantrol autotrawl system with a 3-speed arrangement of 100%, 80% and 60%.  Aft of the wheelhouse are three 20 T split net drums which are also linked to the scantrol system.  Rapp Macgregor also supplied a pair of hinged pins which are arranged just forward of the stern openings and can be raised or lowered remotely, depending on the fishing method and nets being used.

The winches tow a pair of Thyboron type 32 semi pelagic trawl doors and 2 T roller clump.  The gear is monitored by a Marport system with sensors on the trawl doors and clump measuring depth, height, distance, pitch and roll with a further sounder measuring the distance each door is off the seabed.  There are a further 2 symmetry sensors mounted on the headline of the net.  Nordso Trawl supplied the twin rig nets along with a single net and high lift pair trawl net with Scot trawl supplying the codends and extensions and Jackson Trawl the combi line sweeplines.

The crew accommodation is arranged entirely on the main deck and comprises a changing area with deck WC and shower forward to port accessible from the processing area.  Once into the main living quarters 2 x 4 berth cabins, 2 x 2 berth cabins and WC facilities are positioned from midships forward.  Aft of the cabins there is a dedicated lounge area and then a combined galley mess. 

The wheelhouse is arranged with a forward control area and an aft raised control area for fishing operations.  H Williamson and Sons supplied the wheelhouse electronics detailed below.

Venture IV

Venture IV


Macduff Ship Design are delighted to announce the completion and delivery of the, ‘VENTURE IV’, to Mark Lovie of the Venture II Fishing Company Limited.

The vessel is the fourth boat built by Macduff Shipyards for the owner and skipper Mark Lovie. The first ‘VENTURE’ was built by the yard in 1993 as the ‘ENDEAVOUR II’ and was a wooden hull fishing vessel. ‘VENTURE II’ was built by the yard in 2001, this time of steel hull construction and was the largest vessel built by the yard to that date. ‘VENTURE III’ followed suit, handed over in 2017, again being the largest vessel built by the yard at the time. And finally, ‘VENTURE IV’ continues the trend, carrying the distinction of being the largest vessel ever delivered by the yard, both in terms of physical size and gross tonnage.

The project began early in 2020 when the owner expressed an interest to build a new fishing vessel to replace the existing <24m registered vessel. Improving on the fuel efficiency, speed, sea keeping, and crew comfort. Based on their recent experience it was known that to meet these goals that a longer ship would likely be required, free from the constraints of registered length and gross tonnage. As well as increased length, it was decided that it would be advantageous to study the performance of various bow designs in relation to speed and sea keeping, to enable the hull to be optimised to its full potential. At this time we worked closely with Macduff Shipyards and the Wolfson unit at Southampton University. The Wolfson Unit suggested that a program of tank testing be carried out, comparing two hulls of similar overall length. The first featuring a conventional hull with bulbous bow and flared stem, and the second featuring a hybrid bow with an inverted bow for the majority of the stem but still retaining a small flared portion at the top to keep the fore deck dry. Following from this, two scale models were manufactured and then trialled in the Solent University Towing Tank at a range of different speeds, in both calm water and simulated waves representative of the areas which the owner operates. The results from the trial showed a decrease in hull resistance in calm water, mainly due to the increase in waterline length of the new bow. However, more notably the modern bow should a significant reduction in both resistance and motion when being towed into a head sea with waves, particular at higher speeds above 8 knots.

With the research complete the yard and Macduff Ship Design began on the design work, with the hull lines finalised, faired and stability assessed by Macduff Ship Design the construction plans were then drawn up and submitted to Bureau Veritas classification for approval along with the outfitting and engineering drawings. These were then supplied to Finomar Shipyard based in Szczecin, Poland who were sub-contracted to fabricate the hull and wheelhouse which upon completion was towed to Macduff in the late summer of 2021. The full outfitting was completed in Macduff to MCA and BV regulations with the vessel departing Macduff just over a year after arriving to go to Fraserburgh where it docked for a final paint. Sea and fishing trials were conducted in the Moray Firth before the vessel was signed over to the new owners just before Christmas 2022 with enough time for two short maiden trips, fishing off the west coast of Scotland. Early indications are that the hull is performing as anticipated with increased speed, reduced fuel consumption, and improved sea keeping evident.

The hull is of round bilge form with a streamlined inverted bow, flared upper stem, beam carried full length to the transom and possesses two complete decks, as well as a partial shelter and bridge deck above this. A ballast box keel is fitted along with deep ‘V’ bilge keels to dampen roll motion.

‘VENTURE IV’ features four deck levels which apart from the bridge deck all run the full length of the ship. The arrangement of the ship is based closely on the successful predecessors, ‘ENDEAVOUR IV’, ‘VENTURE III’, ‘ENDEAVOUR V’, which have proven themselves over the years. The longer vessel makes use of the additional space to increase crew comfort and working areas, with large generous cabins and mess areas provided along with a fish hold which can comfortably carry 2000 fish boxes without the need to stack high.

Below main deck is separated into four compartments: aft peak, engine room, fish hold and fore peak.

The aft peak features numerous tanks used to house both fresh water and ships services such a lubrication and hydraulic oil.

Forward of this the engine room houses the main propulsion machinery which is provided by a YANMAR 6EY26W engine rated at 1110 kW at 750 rpm coupled to a free-standing Mekanord 650HS gearbox with a reduction ratio of 5.44:1 which drives the large 3.3 m diameter controllable pitch propeller. A low drag high thrust nozzle is fitted in way of the propeller and incorporates a triple rudder system to provide high turning force. Two YANMAR 6NY16L generator sets are fitted within the engine room, each delivering 280 ekW of power. The main engine and generators are cooled via freshwater plate coolers. The hydraulic towing pumps along with stern thruster are also fitted withing the engine room along with the main electrical switchboard, refrigeration and the ships pumping systems.

A large fish room is fitted forward of the engine room with capacity for up to 2,000 stacking fish boxes. Refrigeration plant and chilling pipes for the fish hold was provided and fitted by Premier Refrigeration along with two 2.5 t Geneglace ice making machines, each feeding into large ice lockers which can house up to 10 t of flake ice.

At the stem of the vessel the fore peak is divided into four compartments with three large freshwater tanks which are used for ice making along with a bow thruster access compartment on the centreline where grey and black water tanks are situated.

Above the main deck the vessel is generally divided along the centreline with working areas to port and accommodation to starboard.  To the port side there is a steering gear compartment combined with engineer’s workshop aft, fish handling area amidships and dry locker forward. To the starboard side there is a laundry/pantry/galley aft, followed by a large mess/lounge amidships and four two-man cabins forward. A large 20 m3 hopper is fitted on the centreline.

A deck up features the trawl deck where most of the deck machinery is fitted, and fishing takes place. The deck features twin ramps aft with hydraulic stern gates fitted to the top of each ramp for crew protection. Forward of these are two flush mounted hopper hatches where the catch is taken onboard. The deck is then open all the way to the stem where three split sweep winches are fitted to allow maximum deck length for storing and mending nets. Fitted amidships immediately above the net tracks are three separate bagging winches. Three split winches are fitted amidships, two to starboard and the third to port and lead directly aft to large trawl blocks which are capable of sliding forward up to 1.2m from the transom to reduce the pressure on the steering gear when towing an edge in deep water. Numerous casings are fitted either side of the tracks and serve various functions such as a gear store, air handling unit room, two-man cabin and unloading trunk.

The shelter deck runs from stern to stem. Aft it is mainly open and provides a walkway around the perimeter of the vessel as well as shelter for those working on the trawl deck. Amidships features a full breadth casing where a skipper’s cabin with en-suite is fitted, along with two two-man cabins, a general WC and electronics room. Forward is arranged for mooring and anchoring and features a three-barrel winch fitted within a weathertight compartment which is used to stow the two anchor warps along with a spare barrel for mooring rope.

At bridge deck level a large wheelhouse is situated which is nearly the full breadth of the vessel to provide great visibility when manoeuvring in restricted areas. Large windows are fitted all around for good visibility with full height windows fitted aft on the centreline, providing a commanding view of the trawl deck to enhance crew safety.

Euroclydon MSY 698

Euroclydon MSY 698

Crab Fishing Vessel ‘EUROCLYDON’ delivery

Macduff Ship Design is delighted to announce the recent completion and delivery to its owners of the MFV EUROCLYDON, GY77.

EUROCLYDON is the second crab fishing vessel built for Stuart MacDougall of fishing company Euroclydon Ltd in the space of only three years. Both vessels were designed by Macduff Ship Design and built by Macduff Shipyards Ltd.

The vessel is built to a full new design of vivier crabber fishing vessel. It features many similarities to the first vessel, MFV LEVANTER, with a similar arrangement throughout. However, with increased length, breadth, and depth, the EUROCLYDON provides noticeably more space all around to enhance crew comfort, sea keeping and fishing activity.

The design work began in the summer of 2020 with consultation between the yard and owner to finalise the general arrangement to their exact needs. With the initial design complete, the construction plans were drawn up by Macduff Ship Design and submitted to the MCA for plan approval under their newly adopted construction standard, inherited from Seafish.

The hull of EUROCLYDON up to the main deck along with the aft accommodation casing and the forward section of the shelter is built from Lloyds grade A shipbuilding plate. The mid part of the shelter where fishing activities take place, along with the wheelhouse and mast is built from marine grade aluminium to help reduce the vessels’ displacement. The hull form features a double chine hull form, transom stern and a modern bow designed to cut cleanly through the sea with less energy leading to a reduction in fuel consumption and emissions along with increased crew comfort.

The layout of the EUROCLYDON below the main deck features two three-man cabins aft, followed by a large engine room which extends forward over the top of the vivier tank. The vivier tank is positioned amidships with its trunk up to the main deck fitted through the engine room. Forward of the engine room, a bait store is situated and finally a water tank is fitted forward of the collision bulkhead in the bow.

Above the deck features the accommodation area aft with galley/mess to starboard, WC aft and a two berth skippers’ cabin and dry locker/laundry to port. Forward of this is the large fully sheltered working deck where the pots are brought onboard, catch emptied into the vivier tank, and pots stacked up until ready to shoot again. The shelter is protected by a large hydraulically powered hatch. The hauler is mounted forward and leads to a block which is fitted at the end of a telescopic boom which extends outboard of the hull to keep the pots clear of the side when hauling up. Forward at the main deck a weather-tight bulkhead is fitted, and a store space is arranged with shelving for storage and the anchor chain locker.

Above the shelter deck, a large open deck space provides for generous stowage of pots when moving gear to the grounds.

EUROCLYDON features some safety features built into the hull such as recessed foot/hand holds beneath the port and starboard fixed side ladders extending below the waterline and permanent guard rails around the wheelhouse perimeter. In addition, the owner’s preference for a raised shooting table is arranged in place of a low deck-level side opening to keep the crew safe within the shelter.

EUROCLYDON is fitted with a large vivier tank with a capacity of over 40,000 litres of seawater. The tank is subdivided with fibreglass grating partitions so the catch can be separated into different species/grades. The tank is serviced by two large electrically powered circulation pumps supplied by Bombas Azcue with the intention of one pump being used in service and one on standby. Overflow pipes are arranged port and starboard, above the waterline, so the crew and skipper can visibly see when the pumps are in operation.

The propulsion setup of EUROCLYDON is based around an innovative, large 2000 mm diameter four-bladed propeller designed and supplied by Wartsila. During the creation of the specification, the yard put forth to the owners a Mitsubishi S6B3 with 320 kW output as the proposed main engine due to its success and fuel economy on other projects in the past. Wartsila was then asked to investigate the optimal propeller diameter and design for the vessel given the engine particulars and a range of gear reductions available. Upon their conclusion, the 2m propeller was selected along with a Masson Marine W6000 gearbox with a large ratio of 8.705:1 which was calculated to provide optimal free steaming thrust per kW of power available. It was witnessed during trials that the vessel achieved a good speed for her length and the propulsion package performed smoothly with little vibration.

A hydraulic system was designed by Macduff Shipyards and features a 1.5 t hauler provided by Britannia Engineering, a telescopic boom for the hauling block and a large hauling hatch supplied by the yard, a KT120 bow thruster with 800 kg of thrust supplied by Kort Propulsion, and a MFB6 landing crane provided by Thistle Marine. Hydraulic power is provided by two large 37.5 kW motors which can be powered separately, or simultaneously, by either of the vessel’s generator sets providing complete redundancy.
