Specifically, the HMNZS Manawanui, a ship which was designed to map the sea floor, which ran aground on a reef, caught fire, capsized, and sank.
As it happens, she was captained by a woman, who was also a lesbian. This would be fodder for jokes as it is, but the way the New Zealand government and media are treating it makes it that much more hilarious, and one can't help but wonder if there will be any kind of serious investigation into this accident (you know, the way there would be for a male captain) to find out what actually happened to make this ship meet with the most ironic fate ever.
