The passage receives its English-language name from the 16th-century English privateer Sir Francis Drake. Drake's only remaining ship, after having passed through the Strait of Magellan, was blown far south in September 1578. This incident implied an open connection between the Atlantic and Pacific oceans.
Half a century earlier, after a gale had pushed them south from the entrance of the Strait of Magellan, the crew of the Spanish navigator Francisco de Hoces thought they saw a land's end and possibly inferred this passage in 1525. For this reason, some Spanish and Latin American historians and sources call it Mar de Hoces after Francisco de Hoces.
The first recorded voyage through the passage was that of Eendracht, captained by the Dutch navigator Willem Schouten in 1616, naming Cape Horn in the process.
The 800-kilometre (500 mi) wide passage between Cape Horn and Livingston Island is the shortest crossing from Antarctica to any other landmass. The boundary between the Atlantic and Pacific Oceans is sometimes taken to be a line drawn from Cape Horn to Snow Island (130 kilometres (81 mi) north of mainland Antarctica). Alternatively, the meridian that passes through Cape Horn may be taken as the boundary. Both boundaries lie entirely within the Drake Passage.
The other two passages around the extreme southern part of South America (though not going around Cape Horn as such), Strait of Magellan and Beagle Channel, are very narrow, leaving little room for a ship. They can also become icebound, and sometimes the wind blows so strongly no sailing vessel can make headway against it. Hence most sailing ships preferred the Drake Passage, which is open water for hundreds of miles, despite very rough conditions. The small Diego Ramírez Islands lie about 100 kilometres (62 mi) south-southwest of Cape Horn.
