Seabourn Cruise Line will end its submarine program in March, in part due to limited guest interest.
Passenger participation rates have been lower than the cruise line had anticipated, it said. Coupled with the specific expertise required to maintain the submarines and have them recertified, the cruise line decided to discontinue the offering after this Antarctica season.
Seabourn also said it was facing more limitations on where it could operate the submarines due to changing regulations.
It said it “will continue to focus on and elevate other aspects” of its expedition cruises, such as zodiac cruising, guided hikes and snorkeling.
The Seabourn Pursuit and Seabourn Venture each have custom-built submarines that can seat six passengers.
A high point for the program came in 2024, when one of Seabourn's submarine expeditions became the first to ever locate the Titania shipwreck site. The German supply ship had sunk 110 years prior, and Seabourn found it in the Chilean Juan Fernandez Archipelago with the help of a local fisherman.
