Joshua Slocum completed the first recorded solo sailing circumnavigation of the world between 1895 and 1898 aboard the sloop Spray.
Slocum had spent decades at sea as a merchant master before the voyage. After losing his commercial command career, he rebuilt an aging vessel given to him in Massachusetts and retained its name, Spray.
He departed Boston on April 24, 1895. His original plan involved the Mediterranean and Suez route, but concerns about piracy and route conditions led him back across the Atlantic toward South America.
Slocum navigated through the Strait of Magellan and then crossed the Pacific, stopping at islands including Juan Fernández, Samoa, and locations in Australia.
His voyage relied on traditional celestial navigation, dead reckoning, charts, and unusual confidence in Spray’s ability to hold a course for long periods with minimal steering input.
Slocum repeatedly emphasized that he was alone. At some ports officials or naval officers inspected or certified the vessel, and his published narrative records efforts to establish that no hidden crew was aboard.
After crossing the Indian Ocean and rounding the Cape of Good Hope, he returned across the Atlantic.
On May 8, 1898 Spray crossed its outward track, completing the geographic circumnavigation; Slocum later returned to Newport, Rhode Island, after more than three years away.
Sailing Alone Around the World, published in 1900, is the core participant source. It is rich in detail but also literary, humorous, and written after the voyage, so exact claims should be checked against port and customs documentation where possible.
Slocum disappeared at sea in 1909 after departing on Spray for another voyage. No confirmed wreckage or final position was found.
For TransitSatellite, the circumnavigation can be mapped by documented ports and major legs without inventing continuous precise positions between them.
