Seaventure Antarctica & Arctic Cruises

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.

Sylvia Earle

Welcome aboard the Sylvia Earle, a purpose-built expedition vessel named in honor of pioneering marine biologist and conservationist Dr. Sylvia Earle.

With a wide range of cabin options, comfortable public spaces, a Mudroom for gear storage, wellness amenities including a heated saltwater pool, sauna, and gym, and multiple zodiac boarding platforms, the Sylvia Earle is both an elegant base camp and an adventure launchpad. Unique to the ship are its tribute decks, honoring not only Dr. Earle but also six other pioneering women in conservation, making the vessel itself a floating ambassador for environmental change.

Douglas Mawson

Adventure has a new name. Setting sail in 2025, our new state-of-the-art ship, the Douglas Mawson, is the last in a line of purpose-built vessels that have redefined small ship expedition cruising. Named after the legendary Australian geologist and explorer, our new small ship embodies Mawson’s pioneering spirit and is designed for global discovery. Featuring the revolutionary Ulstein X-BOW® and purpose-built with enhanced sustainability features, it takes on average 154 adventurers to the world’s wildest places in smooth, quiet comfort. It boasts our most extensive range of cabins yet, including a range of single cabins. The Douglas Mawson features a host of amenities to help you connect with like-minded travellers and elevate your time onboard our floating base camp for adventure. After a long day of exploring, head to the back deck to swim in the heated outdoor swimming pool, find a sun bed to read on, or soak in one of two Jacuzzis. Work up a sweat in the gym before unwinding in the sauna, resolve to learn something new in the Citizen Science Centre, then enjoy a delicious meal with new and old friends in one of two restaurants. Or, with multiple observation areas throughout the ship, simply relax in comfort while you keep watch for wildlife or incredible landscapes unfold before you. While enjoying the luxurious amenities onboard, you can rest assured that our aim to get you off the ship to explore the natural environment as much as possible through our unique activities program remains unchanged. The Douglas Mawson’s inaugural season marks our return to East Antarctica for the first time in 13 years, with new itineraries to include a Mawson’s Antarctica voyage to East Antarctica in honour of the ship’s namesake, departing from Hobart, a semi-circumnavigation of Antarctica, and immersive explorations of the Subantarctic Islands. We invite you to join us on the Douglas Mawson.
