Royal Huisman launched PHI —its new 192ft /58.5m motoryacht — by far the longest motoryacht in the below 500GT category, based on current Classification rules


PHI features sensuous lines designed by Cor D. Rover, who based the general concept, exterior design and interior layout on many in-depth conversations with the owner over a period of years. Relating inside and outside to the ”sectio divina” or the Golden Ratio, PHI is the formula that governs the continuation of dimensions and shapes in natural proportions throughout the design. The PHI philosophy and deck levels are subsequently focused on three themes: the galaxy, the ocean surface and the underwater world.

Rather than just building a large yacht on a so-called shipyard ‘platform’ to enjoy the pleasures of being at sea,” says Cor D Rover, “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.


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.

Owner’s Representative Guy Booth commented: 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.”


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 with its immense experience and track record of innovation in delivering over thirty low-profile and award- winning custom sailing superyachts, Royal Huisman and 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 / 171ft 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 118ft/36m shadow/ vessel —also designed by the same designers and constructed at Alia Yachts in Turkey.
