The 58.5m motoryacht Phi developed and constructed below 500GT is by far the longest motoryacht in this category, based on current Classification rules.

Her exterior was made by Cor D. Rover. The Phi philosophy and deck levels are subsequently focused on three themes: the galaxy, the ocean surface and the underwater world.
Phi’s (still mostly secret!) interior design and styling are defined by the London-based studio Lawson Robb. Her naval architecture is by Van Oossanen Naval Architects. Their specially developed Fast Displacement XL hull form allows this yacht to be long and sleek, yet still remain under the 500 GT mark.

Within the superyacht sector, Phi's fine – and therefore very fuel-efficient – hull lines, together with her very low profile, are considered to be a great challenge to engineer and build. But Royal Huisman is not remotely intimidated by such projects.

As Royal Huisman CEO Jan Timmerman explains: “Just take a look at our two current motoryacht projects: project 403, Phi, and project 406, a unique 52m sportfish yacht that will become the largest of its kind in the world. The individual aspirations and challenges of each of these projects were seen to be well outside the comfort zone by some yards. With the benefit of expert advice, each of these owners brought their highly distinctive individual projects to Royal Huisman, where fresh opportunities for creative problem-solving and innovation were enthusiastically welcomed”.

Phi is scheduled for delivery later this year and will be supported by a matching 36m shadow vessel Phi Phantom, constructed at Alia Yachts.
