Taking Shape: The Remarkable Project Phi

Royal Huisman is pleased to reveal first construction photos of this radical, fast displacement motoryacht’s aluminium hull.

Project Phi was first announced in last summer and, with design engineering well advanced, construction of the aluminium hull began at Royal Huisman’s Vollenhove shipyard in mid-February 2019.

Among a long list of exceptional features of this project are the fuel-efficient hull lines based on the patented Fast-Displacement XL® concept by Van Oossanen Naval Architects, who are responsible to maximise the yacht’s length of over 55m / 180ft while remaining within the sub-500GT category.

The resulting hull will provide a comfortable and stable platform for this radical and high performance vessel, notwithstanding the relatively narrow beam that contributes to Phi’s striking looks.

At this stage we cannot share details of Phi’s exterior design from Cor D. Rover, or of her interior appearance from Lawson Robb. Both remain highly secret. Currently we can only state that Phi will feature extensive external deck space and that proportions throughout her design will be informed by ‘the other Phi’ – the formula within the Golden Ratio that governs the continuation of dimensions and shapes within the natural world. With hull turning scheduled for summer 2019, numerous unique features and specialist aspects of the yacht are being prepared in parallel to the hull construction by the Royal Huisman team, working in close co-operation with the owner’s team and designers.
