Pi – The ultimate superyacht

Jarkko Jämsén, co-founder of Aivan, was invited to create the concept, interior layout and exterior design for a superyacht. In close collaboration with the owner client, he and the other team members created a totally unique vessel from scratch that is custom-made down to every detail.

Pi – originally Syzygy 818 – is a 77.25m motor yacht. The vessel’s top speed is 18.4kn and is powered by two MTU diesel engines. Pi can accommodate up to 12 guests in 6 staterooms, with 18 crew members. Pi has a gross tonnage of 1592.0GT and a 11.0m beam. The interior of the yacht was designed by Sinot.

Pi was built at Feadship – Royal Dutch Shipyards in the Netherlands. Feadship is a cooperative venture between two shipyards Royal Van Lent Shipyard and Koninklijke De Vries Scheepsbouw. Feadship designs and constructs high-end luxury yachts and is one of the leading builders of custom superyachts.

We created the concept and the layout together with the owner’s representative, the owner and myself. It was challenging for me as a designer because the owner was so good that I had to do even better than I thought I could to meet his standards.”
Jarkko Jämsén – Superyacht Times by Georgia Tindale
A full-custom design project needs to be a fun process for both myself and the client. Without the client, there is no boat: it is so much more than just an object.”

"A vessel that is considered exceptional by any measure." The prestigious Motor Yacht of the Year is a sought-after title, and Pi's excellence made her a worthy winner. The judges admired her harmonious exterior lines and the overall perfection of her construction. They also praised the team for coming up with ingenious solutions to engineering challenges.

I am heavily interested in new technology and love pushing the boundaries of what different materials can do. Like windows. This vessel has the most amazing windows ever built on a superyacht.”
