It is understood that the yacht, which was handed over to its owner last week following sea trials, will spend the winter season based in the UK capital.
Royal Huisman chief executive Jan Timmerman described the delivery as "a moment of great pride for our team."
"It is also bittersweet, having to say farewell to PHI, as her creation has been part of our daily lives for several years. At the same time, we know that PHI and her shadow vessel will conquer the oceans."
PHI reached speeds of over 20 knots during sea trials, which commenced after the yacht left the yard's new-build facility in Vollenhove in November.
Designed by Cor D Rover, PHI is a fast-displacement, aluminium superyacht and is set to be the longest sub-500GT yacht in the world, according to today's regulations.
Naval architecture has been penned by Van Oossanen Naval Architects while the interior is from the boards of London design studio Lawson Robb.
PHI features a "sleek, low hull and superstructure profile" with "a range of subtle hints to the natural world that surrounds the yacht”, the yard revealed.
Equipped with Van Oossanen Naval Architect’s XL Fast Displacement Hull Form, PHI is described by the yard as a “technically highly advanced vessel that sets new standards”.
Elsewhere, Cor D Rover previously revealed that the yacht's upper deck will house the owner's "penthouse" apartment, while the main deck will be predominately dedicated to daytime guest activities.
Speaking about the design, Rover said: "Rather than just building a large yacht on a so-called shipyard ‘platform’ to enjoy the pleasures of being at sea, the owner of Phi wanted to build a yacht with a profound underlying story, a deep-rooted knowledge that runs through all aspects of the yacht, from her exterior appearance all the way to internal experience."
The yacht will also boast a patented DEPP swimming pool, which reduces the amount of freshwater used by heating and treating the water when the pool is not in use.
Covered by a flush pool cover, it can become a "sealed tank" at the touch of a button, the yard said. Phi will also feature an "infinite wine cellar" located in the lower deck lobby.
Speaking about the project, owner's representative and project manager Guy Booth said: "All of us involved in the creation of PHI feel a sense of privilege to have had the opportunity to contribute to this innovative project. The co-operation between the owner’s team, the architects, the designers and everyone at Royal Huisman has been exceptional. We can be justifiably proud of what we have achieved."
PHI will have a maximum speed of 22 knots, and will be gyro-stabilised for added comfort. Accommodation on board is for a total of 12 guests, with a staff quarters big enough for 11 crew.
