National Geographic Endurance: Arctic and Antarctic Cruises

Seaventure

Welcome aboard the Seaventure! Seaventure features a 1-A Super ice class rating, the highest ice class awarded to passenger vessels. This means that we will be able to explore coves, bays, and channels that would previously have been forbidden to us. The ship also offers a host of new activities. There’s a sauna, a fitness center, a custom-built citizen science lab, and a heated saltwater pool. There is extra storage space so we can carry more equipment. This allows more of our guests to participate in activities like kayaking, snowshoeing, and camping.

Ocean Atlantic

Ocean Atlantic is the perfect vessel for expedition cruising in Antarctic and Arctic waters! Newly renovated in 2016 and with an international ice class rating of 1B, she is one of the strongest ships operating in Antarctica. Her high maneuverability, shallow draft and strong engines allow for extended voyages into isolated fjords, creating exciting adventures for any Antarctica and Arctic traveler. Ocean Atlantic is newly renovated (2016) with elegant common areas and accommodation for 198 passengers. The ship was built in 1985 and underwent an extensive rebuild in 2010. With a length of 140m, she has ample space on the multiple decks for several lecture halls, a relaxed restaurant serving 4-star international cuisine, professionally staffed bars, and observation platforms – and even a pool. All common areas on the Erickson Deck feature large panel windows, enabling passengers to quickly spot passing whales and photographic sights from the comfort of indoor lounges. All private cabins are stylishly appointed and feature individual bathroom facilities, phone for internal calls, individual temperature controls, and TV. Ideal for relaxation, the vessels’ accommodation ranges in size from 11 - 35 m2 and are designed with either portholes or windows. Daily shore landings at penguin rookeries, research stations, and other Antarctic wonders are made possible by her fleet of 20 Zodiacs.
