PHI
WELL OUTSIDE THE COMFORT ZONE OF MANY OTHER YARDS
"We spoke with most of the pedigree shipyards: we were frustrated to be told ‘you can’t do that’ and so the idea of a sailing boat builder came in.” These are the words of Guy Booth, owner’s representative and project manager of PHI. The sleek hull and low volume of this 58.5m / 192ft motoryacht project presented exceptional engineering challenges. Cor D. Rover, responsible for the general concept, exterior design and interior layout, adds: “Only a sailboat builder has the know-how and ambition to execute miracles on a square inch.”

PHI is a magnificently sensuous motor yacht from the drawing board of Cor D. Rover, who has 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.
PHI’s 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. PHI is by far the longest motoryacht in this category, based on current Classification rules.
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.
