Phi Superyacht – Project Completion

Published 21st March 2023

‘Create something that has never been seen before, create something disruptive, create an unfurling story…..and create it with Phi.’ Our brief from the Owner’s Team based upon the concept developed with Cor D’Rover underpinned every element to this project, from the relationships between the designers and the client, to the collaborations between the professional parties involved, to her design and to her delivery. So far details have been published about her specifications and exterior design but herein lies the beginning to the story of her interior design.


LOA – 58.5m
Beam – 9.73m
Volume – 495GT
Exterior Design – Cor D’ Rover
Naval Architecture – Perry Van Oossanen
Shipyard – Royal Huisman
Interior Design – Lawson Robb
Owners Representative – Guy Booth

With a 58.5m LOA coming in at under 500GT Phi is the longest superyacht ever under this interior volume. Conceived between Perry Van Oossanen and Cor D’Rover, delivered by Royal Huisman all under the directorship of client representative and project lead Guy Booth, the interior needed to fall seamlessly into the projects trailblazing ethos.

Through our research, it was clear that there was nowhere that Phi could not be found. The golden ratio is a cornerstone of both naturally occurring physicality’s as well as those made by man. Some examples may be plain to see, but even where something may be seen as anarchic or chaotic, dig a little deeper and you will indeed find order.

Focusing on one example of Phi as a theme seemed to do the concept a disservice.  Having been briefed by a bold and excited client with; it is key that the design we create is transitional, and that its story unfolds at each turn. The Owners deck explores ideas of astronomy, how myriads of colour and matter can be rationalised through science and geometry. Moving to the Main Deck we present an aft-forward transition from naturally occurring forms & textures to those created by man & technology. In the Lower Deck Guest areas, we have experimented with ways to translate ideas of tectonics in unexpected ways, pairing this with traditions of travel and unearthing the unexpected.

It was vital that none of these rich concepts shouted too loudly, the yacht had to all tie together to be read as one, the design language was to be read in the subtleties.
