Seabourn has marked a major milestone in polar exploration after the Seabourn Venture sailed farther south than any ship in the company’s history.
During a 12-day Antarctica expedition running from January 28 to February 9, 2026, the purpose-built expedition vessel reached an impressive 70 degrees south, setting a new record not only for Seabourn but also for parent company Carnival Corporation.
At the time of the achievement, the ship was the southernmost vessel operating along the Antarctic Peninsula. The moment came as the Seabourn Venture crossed the Antarctic Circle, pushing well beyond the routes typically followed by expedition cruises in the region.
Exploring Rarely Visited Antarctic Waters
One of the standout moments of the voyage was Seabourn’s first-ever exploration of George VI Sound, a remote and largely ice-covered channel that stretches for nearly 300 miles.
The sound separates Alexander Island from Palmer Land and is usually inaccessible due to thick ice conditions.
Guests onboard were able to go ashore directly onto Antarctic sea ice at around 69.5 degrees south, where a champagne toast was held to celebrate the most southerly point ever reached by Seabourn guests.
For many passengers, it was a once-in-a-lifetime experience that combined adventure with a sense of history and discovery.
Stepping Into Polar History at Stonington Island
The expedition also included a rare landing at Base E on Stonington Island, a former British research station that dates back to the mid-20th century. Located at 68 degrees 11 minutes south, Base E is one of the southernmost historic sites on the Antarctic Peninsula and is seldom visited by cruise ships.
Established in 1946 and later rebuilt in 1960, the site played an important role in early Antarctic research, supporting studies in geology, biology and meteorology.
Walking through the preserved buildings offered guests a powerful connection to the explorers and scientists who once lived and worked in extreme isolation.
Throughout the voyage, expert expedition leaders guided Zodiac landings and provided in-depth commentary on wildlife, ice formations and Antarctic history.
Seabourn praised the onboard team for delivering a journey defined by exploration, precision and unforgettable moments, one that truly pushed the boundaries of modern expedition cruising.
