Nonsuch was a vessel which set out for HUDSON BAY from Gravesend, England, 3 June 1668, with Sieur DES GROSEILLIERS and a small crew and anchored off the mouth of the RIVIÈRE DE RUPERT on September 29. A second sailing vessel, the Eaglet, with Pierre RADISSON aboard, was forced to turn back. The 2 French traders had persuaded Prince Rupert and several English investors to finance the voyage to prove that the vast fur resources of interior North America could be tapped via Hudson Bay. The Nonsuch' s crew wintered in James Bay and reached England on 10 October 1669 with a cargo of furs that the press reported "made them some recompense for their cold confinement." The charter for the HUDSON'S BAY COMPANY was granted on 2 May 1670.

In 1968 a replica of the Nonsuch was built in England to honour the 300th anniversary of the voyage. It was shipped to Montréal in 1970 and displayed on the Great Lakes and Pacific coast before being installed in a specially built museum in Winnipeg. The replica is considered to be the most accurate reconstruction of a 17th-century ship.
