Royal Huisman's 58.5m PHI Captured on Sea Trials

Instantly recognisable for her electric blue hull and superstructure, PHI (formerly Project 403) is the largest superyacht in the world below 500GT. 

Guy Booth, Owner’s representative and project management, comments: “With such a powerful vision, a demand for the absolute highest level of quality available anywhere and such difficult engineering challenges, Royal Huisman were clearly the best partner to build the boat.”

Designed to provide a low profile, angular lines and an extensive degree of outdoor living, PHI is also extremely fuel-efficient. Her exterior design and interior layout is penned by Cor D. Rover, with naval architecture by Van Oossanen. Lawson Robb is responsible for her interior design. 

Renowned for building some of the most admired sailing yachts in the world, such as 81m SEA EAGLE II delivered last year, PHI’s launch is not Royal Huisman’s only recent project marking a shift away from the yard’s traditional sailing yacht specialism. Project 406, announced earlier this year, is also in-build at Royal Huisman; the 52m motor yacht will be the world’s largest true sportfish yacht when launched.

PHI's support vessel, 36m PHI Phantom, was also launched earlier this year at ALIA Yachts in Turkey, donning the same electric-blue and yellow accent as her mothership. “As far as we’re aware, this is the first support ship that’s been built with shared aesthetic DNA from the mothership,” Guy Booth commented on her launch.
