The Singapore Strait is a 105-kilometre-long (65 mi) * , 16-kilometre-wide (9.9 mi) * strait between the Strait of Malacca in the west and the Karimata Strait in the east. Singapore is on the north of the channel, and the Riau Islands are on the south. The Indonesia-Singapore border lies along the length of the strait.


It includes Keppel Harbour and many small islands. The strait provides the deepwater passage to the Port of Singapore, which makes it very busy. Approximately 2,000 merchant ships traverse the waters on a daily basis. [2] The depth of the Singapore Strait limits the maximum draft of vessels going through the Straits of Malacca, and the Malaccamax ship class.

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, [3] although others generally considered it the Malacca Strait, a point of contact between the Arabs and the Zābaj (likely Sumatra). [4] 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. [5] 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. [6] Today the Singapore Strait refers to the main channel of waterway south of Singapore where the international border between Singapore and Indonesia is located.

Strait of Malacca Strait between the Malay Peninsula and the Indonesian island of Sumatra

The Strait of Malacca or Straits of Malacca is a narrow, 550 mi (890 km) stretch of water between the Malay Peninsula and the Indonesian island of Sumatra. As the main shipping channel between the Indian Ocean and the Pacific Ocean, it is one of the most important shipping lanes in the world. It is named after the Malacca Sultanate that ruled over the archipelago between 1400 and 1511, the center of administration of which was located in the modern-day state of Malacca, Malaysia.

Malacca Sultanate historical state in Malaysia

The Malacca Sultanate was a Malay sultanate centred in the modern-day state of Malacca, Malaysia. Conventional historical thesis marks c. 1400 as the founding year of the sultanate by a Malay Raja of Singapura, Parameswara, also known as Iskandar Shah. At the height of the sultanate's power in the 15th century, its capital grew into one of the most important entrepôts of its time, with territory covering much of the Malay Peninsula, the Riau Islands and a significant portion of the northern coast of Sumatra in present-day Indonesia.

Port of Singapore port

The Port of Singapore refers to the collective facilities and terminals that conduct maritime trade, and which handle Singapore's harbours and shipping. It is ranked as the top maritime capital of the world since 2015. Currently the world's second-busiest port in terms of total shipping tonnage, it also trans-ships a fifth of the world's shipping containers, half of the world's annual supply of crude oil, and is the world's busiest transshipment port. It was also the busiest port in terms of total cargo tonnage handled until 2005 when it was surpassed by the Port of Shanghai. Thousands of ships drop anchor in the harbour, connecting the port to over 600 other ports in 123 countries and spread over six continents.

Johor Sultanate sultanate

The Johor Sultanate was founded by Malaccan Sultan Mahmud Shah's son, Sultan Alauddin Riayat Shah II in 1528. Johor was part of the Malaccan Sultanate before the Portuguese conquered Malacca's capital in 1511. At its height, the sultanate controlled modern-day Johor, Riau, and territories stretching from the river Klang to the Linggi and Tanjung Tuan, Muar, Batu Pahat, Singapore, Pulau Tinggi and other islands off the east coast of the Malay peninsula, the Karimun islands, the islands of Bintan, Bulang, Lingga and Bunguran, and Bengkalis, Kampar and Siak in Sumatra. In 1564 the Ottomans conquered the Sultanate during the Ottoman expedition to Aceh. During the colonial era, the mainland part was administered by the British, and the insular part by the Dutch, thus breaking up the sultanate into Johor and Riau. In 1946, the British section became part of the Malayan Union. Two years later, it joined the Federation of Malaya and subsequently, the Federation of Malaysia in 1963. In 1949, the Dutch section became part of Indonesia.
