Sir John appeared in the 1801 Register of Shipping with W. Neil, master, Noble & Co., owners, and trade Plymouth–India.

Homeward bound, she was at Saugor on 13 September, and reached the Cape of Good Hope on 30 December and St Helena on 28 January 1802.

[4] Sir John Borlase Warren left St Helena on 31 January 1802, in company with Nutwell.

[6] Sir John sailed in March 1806 as one of seven cartel ships repatriating to Holland the Dutch troops captured at the Cape, and their dependents.
