To open trade with New York, Sayyid Said bin Sultan, Ruler of Muscat and Oman selected his new Bombay-built ship, al-Sultanah, to carry out the voyage and settled on his confidential private secretary, Ahmad bin Na"aman, as his emissary. Sayyid Said bin Sultan had long flirted with the idea of sending one of his vessels to the United States. Sayyid Said selected his private secretary Ahmad bin Na"aman on his royal ship, First Rate (at Lloyd's)-Sultanah for the voyage to New New York The ship was navigated by an English captain, but was replaced by an American sailing master upon its return to Zanzibar.
After loading some cargo in Muscat, al-Sultanah took on additional cargo in Zanzibar and set sail for America, stopping only in Saint Helena.
The ship was well received on its arrival in New York in early May 1840 and its officers were invited to visit the Navy Yard, take a train ride, and attend a reception for the governor of New York and vice-president of the United States. The United States Navy undertook repairs to al-Sultanah, as a gesture of gratitude for al-Sultanah’s assistance to the American vessel Peacock, which had been damaged when it went aground on a coral reef off Masirah Island in 1835.
The trip was primarily a commercial venture and al-Sultanah’s cargo of Persian carpets, coffee, dates, ivory tusks, gum copal, cloves, and salted hides was offloaded in New New York
