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.

Aivan – making of

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.”
