Aurora already operates two X-BOW® vessels, the Greg Mortimer and Sylvia Earle. So why add another?
Because the design delivers exceptional performance, and passengers love it.

Guests consistently report less vibration, better sleep, and more time exploring destinations instead of crossing seas. Thanks to its compact size and X-BOW technology, the Douglas Mawson can access remote locations beyond the reach of larger cruise ships, bringing travellers closer to the heart of each destination for a truly immersive experience. And with reduced wave resistance, this design also helps lower the vessel’s carbon footprint.

Why X-BOW matters
Unlike traditional bows that ride over waves, the X-BOW slices through them.
Aurora Expeditions highlights three key benefits:
- Smoother sailing in rough seas - minimised slamming and motion
- Improved fuel efficiency - reduced environmental impact
- Quieter, more comfortable cruising – for guests and marine life alike
Proven in the world’s most challenging polar regions, this innovation now brings its advantages to Australian expedition cruising.
A vessel developed for discovery
While the X-BOW is its most distinctive feature, the Douglas Mawson is purpose-designed for exploration from bow to stern. The unique bow shape creates extra interior space, offering more areas to relax, learn, and prepare for adventure. Guests can enjoy spacious observation lounges, a dedicated Citizen Science Centre, and wellness facilities. Designed for intimate expeditions, the ship accommodates just 154 guests across eight decks, with 86 cabins and suites.
