Seabourn's first new ultra-luxury purpose-built expedition ship will be named Seabourn Venture, the company said in a statement.
The vessel and a second yet-to-be-named sister ship will be built by T. Mariotti of Italy. These will be designed for diverse environments to PC6 Polar Class standards.
Seabourn Venture will have 132 oceanfront veranda suites and will be able to carry two custom-built submersibles plus a number of kayaks and 24 inflatable boats.
The vessel is scheduled to be launched in June 2021.
