Not an invention, but one of my favourite failures is Shackleton’s antarctic expedition[1], which among the many trials includes what must be one of the greatest navigational feats in history: 1300km in an open boat across the Antarctic Ocean after a year being stuck in the ice.

Bligh’s open boat voyage[1] after the mutiny on the Bounty has them beat at 6400km, but the Shackleton expedition certainly had to deal with much more adverse conditions.
