The ship is registered in Nassau in the Bahamas.
MV Orion was built by Cassens shipyard in Germany in 2002 for the Marshall Islands-registered company Explorer Maritime.
In March 2013 Orion Expeditions was acquired by the US-based small-ship operator Lindblad Expeditions, which owns five ships and charters a further five and operates cruises to a variety of destinations.
The MV Orion was renamed National Geographic Orion in March 2014.
■ Just the year before, on the evening of January 29, 2013, the MV Orion rescued a round-the-world sailor, Alain Delord, from his liferaft which had been located 487 nautical miles south-south-west of Hobart in the Southern Ocean. He had abandoned his yacht after it lost its mast and the hull was damaged in rough weather.
The ship was on its way from Antarctica to the world heritage-listed Macquarie Island when it responded to the call for help.
The captain of the Orion, Mike Taylor, undertook the 1500 km rescue in moderate to rough seas from Antarctica’s Commonwealth Bay.
In a race against time, the ship successfully tracked the sailor’s emergency radio beacon and effected the rescue with just an hour of daylight left.
■ The Heritage Adventurer will be the next cruise ship to call here, on November 18.
