Luxury yacht PI (ex SYZYGY 818 and a.k.a SYZYGY, ex.PROJECT 818) is a 77.3m/253.6ft vessel from Dutch shipyard Feadship and features a steel hull and aluminium superstructure. Her naval architecture comes from De Voogt Naval Architects, the exterior styling is the work of Jarkko Jämsén - Aivan and the interiors come from Sinot Yacht Architecture & Design.

NOTABLE FEATURES OF PI: ~ Prestigious shipyard ~ Extensive sunbathing and alfresco dining areas ~ Spacious interiors ~ Air conditioning ~ Wi-Fi


The number 8 is considered lucky in Chinese numerology and as such, the project number '818' was considered especially lucky. Added to the fact that the Owner's birthday is on August the 18th and the number was added to the superyacht's official name. The other half of her name, 'Syzygy', is a term in astrology for the rare event when three heavenly bodies line up perfectly in the heavens, in such events as a lunar eclipse or new moon.

As a pure custom luxury yacht, PI has been personalised for her Owner and has top-of-the-line glass technology to create the curvaceous superstructure from the computerised 3D design. The Owner also had sustainability goals that needed to be met, and to reach these the electronics and engineering had to provide excellent fuel efficiency.


From the lower deck swim platform guests have access to the stern interior as well as the main deck aft. In addition to the spacious main deck aft, which can be laid out for casual lounging or alfresco dining, there is a spacious upper deck aft with side walk ways that connect around to the flush foredeck. The sundeck above has the best views on board for observation of the surroundings.

Quick Enquiry

“The way we design, is we design fully custom, fully unique yachts, we start with a blank piece of paper and we start asking the client how they use the boat, what they want to do on board, what kind of experience they have but we also want input on what kind of styling they like... It’s about getting to learn about the owner and how they want to use the boat.” - Ronno Schouten, Design Manager of De Voogt Naval Architects
