Project PHI’s 55-metre hull was wheeled underneath her superstructure at Royal Huisman’s facilities in Vollenhove, Holland.

Royal Huisman’s Project PHI is now in the shipyard’s largest Shipbuilding Hall 2 which provides the room for precise alignment, assembly and further outfitting of this fast displacement, sub-500GT superyacht.

PHI’s narrow and fuel-efficient hull – based on the exterior design of Cor D. Rover and naval architecture by Van Oossanen Naval Architects – was engineered and constructed in the shipyard’s Shipbuilding Hall 1 and was turned on its keel for completion late last year.

PHI’s superstructure was equally well-prepared and detailed by all main engineering departments of the shipyard, but its production was outsourced.

PHI features exterior design from the drawing board of Cor D. Rover, interior design by Lawson Robb and naval architecture by Van Oossanen Naval Architects. Relating 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.

PHI’s creation was the result of many in-depth conversations over a period of years, between the experienced Owner and Cor D. Rover. The especially developed Fast Displacement XL hull form from Van Oossanen allows this yacht to be 55-metres and still remain under the 500 GT mark.

Throughout, the team of PHI has been very aware that a major area of focus is the challenge to install comprehensive machinery and technical systems within the relatively low volume of a long, slender hull.

The hull was designed to meet high performance objectives which include simplicity in operation and maintenance.

Consequently, the Owner appointed Royal Huisman to call upon their technical expertise in this specific area.

PHI’s design was initially shrouded in secrecy when the project’s contract was signed mid-2018, but in the meantime various detailed previews were unveiled to show off the radical looks of PHI (and her matching shadow vessel; also designed by Cor D. Rover and Van Oossanen Naval Architects and currently under construction in Asia). Various previews reveal a design true to the project’s philosophy, of a completely bespoke exterior, which incorporates numerous beautiful (and patented) technically innovative features.

PHI is scheduled for delivery in 2021.
