The 199GT shadow superyacht is under construction in Turkey
Turkey’s Alia Yachts has turned the aluminium hull of its first 36-metre all-aluminium shadow vessel, which is slated for delivery in 2021. Once complete, the vessel will support 55-metre Project Phi, the mothership currently under construction at Royal Huisman’s Vollenhove yard in the Netherlands.
The 199GT shadow superyacht will be used to transport tenders and toys, as well as a small car and extra fuel for the mothership to extend its range. It will have a 157-square-metre cargo deck, 45-square-metre lazarette and a 33-square-metre workshop, and provide additional crew accommodation.
Both the shadow vessel and the mothership have exterior styling by Dutch designer Cor D Rover and naval architecture by Perry van Oossanen, long-term Alia partners.
“Although she’s basically a workhorse, with lots of storage for tenders and toys and a big 11.5-metre reaching 15,500kg capacity crane, the exterior lines and details have been styled to resemble the mothership,” says Rover. “So, there is a distinct family resemblance, but as a shadow vessel her prime function is to support the bigger yacht.”
“We developed the naval architecture and engineering together with the captain, who provided a lot of input,” says van Oossanen. “Like the mothership, the vessel has a Fast Displacement XL hull form, which combines the speed and efficiency advantages of the FDHF concept with the maximum length within a given gross tonnage category for optimal seakeeping and comfort.”
Powered by twin CAT C-32 main engines for a top speed of 21 knots, the shadow vessel will have a range of 4,200nm at a cruising speed of 12 knots. This means it will have the ability to travel ahead of the mothership to make sure all the toys and tenders are ready for guests upon their arrival, and remain behind to load the tenders when the mothership moves on to the next destination, minimising waiting periods.
“This is a very interesting project for us which we foresee will provide a platform that can be adapted to meet the growing needs of other superyacht owners,” says Gokhan Çelik, president of Alia Yachts. “The principal challenge is that it has to be fast but also versatile and efficient. I’m particularly happy because the Owner decided to build with us after visiting the shipyard and seeing the quality work we do.”

The 55-metre Project Phi is a radical, fast displacement, sub-500GT motor yacht, currently scheduled for delivery in 2021. The superyacht’s narrow, fuel-efficient hull was rolled out of the construction hall for her scheduled turning in October 2019.
Lawson Robb has been appointed to design Phi’s interior spaces, which are said to take inspiration from nature, space and the Golden Ratio, but for now, remain a guarded secret.

Utilising the specially developed Fast Displacement XL hull form from van Oossanen allows the yacht to have an overall length over 55m while still remaining under the 500GT mark.
