Strait of Hormuz
AboutGulf of Oman in the southeast and the Persian Gulf. On the north coast is Iran and on the south coast is the United Arab Emirates and Musandam, an exclave of Oman.
The strait at its narrowest is 54 kilometres (34 mi) wide. It is the only sea passage to the open ocean for large areas of the petroleum-exporting Persian Gulf. About 13 tankers carrying 15.5 million barrels (2,460,000 m3) of crude oil pass through the strait on an average day, making it one of the world's most strategically important choke points. This represents 33% of the world's seaborne oil shipments, and 17% of all world oil shipments in 2009.
There are two opinions about the etymology of this name. In popular belief the derivation is from the name of the Persian God هرمزHormoz (a variant of Ahura Mazda). Compare the Pillars of Hercules at the entrance to the Mediterranean. Scholars, historians and linguists derive the name "Ormuz" from the local Persian word هورمغ Hur-mogh meaning date palm. In the local dialects of Hurmoz and Minab this strait is still called Hurmogh and has the aforementioned meaning.
Swimming the length
According to the Guinness Book website: The first, and therefore fastest, swim along the length of the Persian Gulf is by 34-year-old Mohammad Kobadi (Iran). In 84 days between 19 December 2011 and 12 March 2012, Kobadi swam 1,051 km (653 miles), in stages, from the Strait of Hormuz to Arvand Kenar along the coast of southeastern Iran, averaging 11.7 km (7.2 miles) per day. The achievement was ratified by Open Water Source.
