Ship history

2017: Australia-based polar adventure cruise company Aurora Expeditions is to name its first purpose-built, ice-class expedition ship Greg Mortimer in honour of the company’s founder when she debuts in late 2019.

The expedition vessel, ordered by US-based company SunStone Ships at China Merchant Industry Holdings, will also be the first to use Ulstein Group’s patented X-BOW hull design, which has a tapered fore ship shape so it can pierce waves of all heights. This reduces pitching and bow impact loads in rough seas, preventing the vessel from rising on the waves and dropping violently onto the water’s surface as it would with a traditional bulbous bow. It also takes less fuel for the vessel to cut through the waves, reducing fuel costs and energy use.

Other highlights will include a custom-designed platform for kayakers and divers, a dedicated sea-level Zodiac loading platform, and a mud room for climbers and skiers.

From 2019, the Greg Mortimer will hit the open waters of Antarctica and the European Arctic. It's not just the X-BOW® that makes this ship stand out from the rest of the Aurora Expeditions fleet. Here are some other features to look out for:

  • Observation decks that offer a range of views out to the spectacular panoramic scenery
  • Hydraulic platforms bringing the passengers closer to the action from the comfort of the ship
  • State-of-the-art lecture rooms for informative talks and briefings
  • Dedicated zodiac docks which make loading and unloading easier than ever
  • On-board changing room/mudroom for storing outdoor clothing and gumboots after an adventure
  • Restaurant and bar serving up a delicious daily menu
  • Relaxed staterooms ranging from porthole to balcony categories

The passengers will be able to also enjoy a number of activities during your voyage, using the ship as their base. This includes:

  • Sea kayaking
  • Diving and snorkelling
  • Snowshoeing
  • Ski touring
  • Climbing
  • South Georgia alpine crossing
  • Camping
  • Photography workshops
