Forever Faithful
AWARDS 2024 | Best Scalloper – Eternal Promise
Macduff Ship Design is excited to announce the ‘Eternal Promise’ has received the best scalloper 2024 award from Workboat World, the 19.98m scallop boat built for coastal waters is a development from the previous vessels offering increased deck/fishing gear space, improved crew welfare, with accommodation for seven, a more efficient hull form, and a new stern gear package with an aim to improve overall fuel efficiency.
The Hull was developed in the early design phase through various iterations testing different bulbous bow shapes to identify the best reduction in resistance, by carrying out CFD analysis for vessel hull forms, it ensures that new designs are always improving, lets the yard test its design concepts and to make sure they work before putting into production.
The Eternal Promise is a sister ship to two other vessels, and the third in a successful series of efficient trawlers that carry a good speed and a high bollard pull for quite modest engine power.
The layout of the blast freezing and cold store compartments was researched thoroughly and discussed with the refrigeration specialist to ensure that the temperatures to freeze the product could be reached and maintained efficiently. Being able to freeze the volume of fish product in the small spaces onboard was seen as a great success, with efficient use of space.
AWARDS 2024 | Best Prawn Trawler – Forever Faithful
Macduff Ship Design are delighted to receive the Best Prawn Trawler 2024 award from Workboat World.
‘Forever Faithful’ is the third in a series of vessels including ‘Celestial Dawn’ built 2022, and ‘Zenith’ built 2023. The newbuild has a LOA of 22.75 metres, a beam of 7.6 metres, a depth of 4.15 metres, with a displacement of 298 tonnes, and a gross tonnage of 224. The fish hold has a capacity of 600 boxes while catch freezing facilities are also available.
The vessel designed in collaboration with Macduff Shipyards , with the Wolfson Unit in Southampton being commissioned to run a case study of two hull forms utilising CFD technology, this brought about significant changes to the old hull form, thus resulting in a new form with significant efficiency improvements. Results from the study indicated a significant reduction in hull resistance at the two test speeds of eight and 10 knots, which has been verified. The new vessel is able to steam around one knot faster at full engine power than the previous vessel, though both vessels have the same engine type and available power.
