Singapore Strait

The 9th century AD Muslim author Ya'qubi referred a Bahr Salahit or Sea of Salahit (from the Malay selat meaning strait), one of the Seven Seas to be traversed to reach China. Some have interpreted Sea of Salahit as referring to Singapore, although others generally considered it the Malacca Strait, a point of contact between the Arabs and the Zābaj (likely Sumatra). Among early Europeans travellers to South East Asia, the Strait of Singapore may refer to the whole or the southern portion of the Strait of Malacca as well as other stretches of water. Historians also used the term in plural, "Singapore Straits", to refer to three or four different straits found in recorded in old texts and maps – the Old Strait of Singapore between Sentosa and Telok Blangah, the New Strait of Singapore southwest of Sentosa, the "Governor's Strait" or "Strait of John de Silva" which corresponds to Phillip Channel, and the Tebrau Strait. Today the Singapore Strait refers to the main channel of waterway south of Singapore where the international border between Singapore and Indonesia is located. ==Extent==

Pilot guides and charts of the Malacca and Singapore straits have been published for a considerable time due to the nature of the straits ==Second World War==

In 2009, the Maersk Kendal was grounded on the Monggok Sebarok reef. In 2024, ReCAAP reported targeted stealing of engine spares by pirates as unique to the Singapore and Malacca Straits, indicating the possibility of a black market. In 2025, a major increase in piracy incidents was reported in the Singapore Straits by The International Maritime Bureau (IMB) Piracy Reporting Centre. These have included boardings and violent armed robberies of cargo ships. Over 60% of global piracy occurred in the Singapore Straits in this year. ==See also==
