VESSEL BUILD, REPAIR & MAINTENANCE Fishing Vessel ‘ENDEAVOUR V’
Macduff Ship Design are pleased to announce the delivery of the Stern Trawler MFV ‘ENDEAVOUR V’. The vessel completed by Macduff Shipyards was the fifth to be built by the yard for skipper Peter Lovie of Knockhead LLP of Whitehills, compounding a working relationship of over thirty-five years culminating in the largest vessel ever delivered by the yard.
The project began in the summer of 2017 when the owner expressed an interest to build a new fishing vessel with a desire to improve fuel efficiency, service speed and sea keeping from their existing vessel. An early study between the yard and Macduff Ship Design concluded that to achieve this a longer ship, free from the constraints of registered length, would likely be required. It was at this point that the Wolfson Unit based in Southampton was contracted to complete an initial trial using CFD technology to assess the differences in calm water hull resistance between the existing model and a new longer concept model. As expected, the data showed that a significant reduction in hull resistance could be achieved with a longer hull form, however, the computational based analysis could not assess the differences in sea keeping qualities. To answer this question the Wolfson Unit conducted a further trial but this time towing representative scale models in the Solent University Towing Tank facility. Both hull forms were assessed at a range of speeds in both calm water and head seas with wave properties reflecting those found in the north Atlantic where the owner typically operates. As well as confirming the reduction in hull resistance between the two models the tank testing also enabled sea keeping to be measured and it was conclusive that longer hull experienced considerably less pitching motions along with lower bow impact from wave force.
With the research complete the yard and Macduff Ship Design took one final review of the hull form and the decision was made to lengthen the hull by a metre to seek further improvements in hull efficiency as well as affording a little more space within the vessel.
With the hull lines 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 Szezcin, Poland who were sub-contracted to fabricate the hull and wheelhouse which upon completion was towed to Macduff in November 2019. The full outfitting was completed in Macduff to MCA and BV regulations with the vessel departing Macduff less than one year after arriving to Fraserburgh where it was 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 who departed their maiden trip, 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 form is of round bilge with a streamlined bulbous bow, flared stem, beam carried full length to the transom and possesses two complete decks,

as well as partial shelter and bridge decks. A ballast box keel is fitted along with deep ‘V’ bilge keels and a roll reduction tank to dampen roll motion.
Endeavour V features four deck levels which apart from the bridge deck all run the full length of the ship. The arrangement is based closely on the successful Endeavour IV which has proven itself well over the years but makes use of the additional space to increase crew comfort, fish hold capacity and working deck areas.
Below main deck is separated into four compartments; aft peak, engine room, fish hold and fore peak.
