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:

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.
