Immortalis was built in 1996 by Niigata shipyard for the Japanese government as a sicentific research vessel. Her work included seismic surveying, fish stocks monitoring, carrying large loads and also worked as a crew training vessel.

She has a comprehensive setup of military grade equipment throughout the boat. Every system has a failsafe full backup system. 

In 2020/2021 she was undergoing an extensive refit to become a specialized expedition vessel.

Key highlights to the refit:

  • 18t of steel added to keep to improve stability
  • Purpose built great room for conferencing/dining/working
  • Expansive back deck for working and storage
  • Sun deck and helipad deck for additional amenities
  • Purpose built galley for long expeditions and gourmet food

Immortalis is a long-range expedition style yacht. The refurbished vessel marries modern contemporary style with glimpses into her former life as a scientific research vessel. The relaxed yet functional environment is available for guest to enjoy, relax and explore in tailor made fashion.
