The Drake Passage is the body of water between South America’s Cape Horn, Chile, Argentina and the South Shetland Islands of Antarctica. It is considered one of the most treacherous voyages for ships to make. Currents at its latitude meet no resistance from any landmass and waves top 40 feet, giving the passage a reputation for being the location of the most powerful convergence of seas. More than 800 ships are believed to have succumbed to its waters. More than 20,000 sailors are believed to have perished in the area.
