I first read about Shackleton long ago, and I've been a huge fan of his exploits. He never actually accomplished the goals he set out for, but he was a master of revising goals and probably one of the best examples of great leadership I've ever read. As an Anglophile, I've also been intrigued by the concept of the 'Magnificent Failure' which sometimes seems to be a uniquely British concept.
Certainly Shackleton deserves his name on a polar research ship. But in a magnificent failure, the British botched the naming process for the ship. Well, temporarily botched. I happen to like "Boaty McBoatface" over "Shackleton" it just seems like a ship where stuff gets done.
