Several vessels in the 19th century were named Sincapore, a contemporary variant of the name Singapore:

The brig Singapore, of Bengal, had arrived the day before.  had found her near Delagoa Bay in the hands of the Portuguese government. Only one of her crew was still alive; the master and all the rest had died of disease. The government had landed her cargo. Captain Owen prevailed on the government to reload the cargo. He then put a crew on board Singapore and sent her into the Cape. There was another vessel at Delagoa Bay, the schooner Orange Grove, which too had lost all but her master and supercargo, and whose cargo too the government had landed. Orange Grove sailed to the Cape in company with Singapore. Captain Owen, in his account of his explorations, refers to Singapore throughout as Sincapore.

Sincapore was a steam-ship operating in Asian waters in 1854.
