The Ocean Endeavour
This is the fourth post on Antarctica. Prior posts focused on the landscapes and wildlife of Antarctica, plus Deception Island.
The Ocen Endeavour is an expedition-class ship that bounces between the poles depending on season (i.e. summer in each). It operates under long-term contracts with different tour operators (I went with Intrepid Travel).
Built originally in 1981 in Poland and has been refitted (and renamed) several times before becoming the Ocen Endeavour in 2014. It holds roughly 200 passengers (a common limit for Antarctic vessels) plus boat crew and expedition staff.
