Holdfast

Holdfast was the largest capacity high-speed crayboat in Australia when we launched it in early 2018.

Owned by the Cockman family, which has been fishing commercially for some 50 years, Holdfast operates multi-day voyages, far offshore placing greater emphasis on vessel and systems reliability, seakeeping, and habitability for personnel onboard than more typical ‘day boats’.

As a result its design and construction pays considerable attention to comfort for the up to nine personnel for which sleeping accommodation is provided. This included applying our expertise in noise reduction to ensure all wheelhouse and accommodation areas are very quiet, achieving 71dB at full power.

The aluminium and composite monohull was the first vessel completed in the larger facilities that we expanded into during 2017. In addition to managing vessel construction, including the composite wheelhouse, Dongara Marine undertook all engineering and fitout; acid sealing and painting; electrical work; installation of the windows; and project management of specialist subcontractors who contribute to building a vessel of this size and complexity.

We achieved 100 per cent schedule compliance throughout and, more importantly, customer satisfaction, the owner stating:

“This was the seventh boat we have had built and despite it being the largest and most complicated, it was also the easiest build process. We were able to work really well with the guys at both Southerly and Dongara Marine.”

Holdfast is a milestone in the history of Western Australia’s world-renowned commercial boatbuilding industry having been, at the time of its delivery, the largest capacity of any of the hundreds of high-speed crayboats built for Australia’s fishing industry over the decades.

“The real highlight was just how good it has been working with Rohan and the team at Dongara Marine.”
