Ocean Atlantic Antarctic and Arctic 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.

Greg Mortimer

The Greg Mortimer is a state-of-the-art expedition vessel designed to navigate the world's most remote and pristine environments. As the first passenger ship to feature the revolutionary ULSTEIN X-BOW®, it offers smoother and more efficient sailing, even through challenging polar waters. Accommodating up to 132 passengers, the ship provides an intimate and comfortable setting for exploration. Its advanced design includes hydraulic viewing platforms and expansive observation decks, bringing you closer to the breathtaking landscapes and wildlife of the Arctic and Antarctic. Choose from a variety of staterooms and suites, many with private balconies and floor-to-ceiling windows. Each cabin is thoughtfully appointed with en suite bathrooms, ample storage, and modern amenities, ensuring a restful retreat after a day of adventure. With a fleet of 15 Zodiacs, the Greg Mortimer facilitates frequent and flexible landings, allowing guests to explore secluded sites up close. The ship offers a range of optional activities led by expert guides, including kayaking, diving, climbing, and ski touring. Educational lectures and a well-stocked library enrich the journey, providing deeper insights into the regions visited.

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.

Sylvia Earle

Welcome aboard the Sylvia Earle, a purpose-built expedition vessel named in honor of pioneering marine biologist and conservationist Dr. Sylvia Earle. Launched in late 2022, this state-of-the-art ship combines advanced nautical design with a deep respect for the natural world. Carrying a maximum of 130 guests, the Sylvia Earle fosters a more intimate, community-focused experience, where like-minded travelers can connect meaningfully while exploring the planet’s most remote and awe-inspiring polar regions. The ship features the revolutionary Ulstein X-BOW® design, which cuts through swell for smoother sailings and increased fuel efficiency. 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.
