Sailing north, Hanna discovers and names a number of inlets and islands on the west coast of Vancouver Island.

He makes a chart of those parts he visits and bestows the name of his patrons on several places, such as Cox’s Island, Lane’s Bay, Fitzhugh Sound, Lance’s Islands and MacIntosh’s Inlet.

Seeing land to the north, which is probably the islands off the continent or even Kunghit Island, the southernmost of the Queen Charlotte Islands, the Irishman James Hanna names it Nova Hibernia, complete with a St. Patrick’s Bay.

These names, except Fitzhugh Sound, Cox Island and Lance’s Island (now spelt, in the Spanish way Lanz Island), will be ignored by later cartographers.

He then moves south to Clayoquot Sound on the west coast of Vancouver Island.

Clayoquot Sound is the home of the powerful chief Wickaninnish, who is one of the dominant figures in the maritime fur trade at the end of the eighteenth century.

The population of the large, island-filled bay probably numbers over four thousand at the time of Hanna’s visit.

The village of Opitsat on Meares Island, opposite the present-day settlement of Tofino, is considered the largest native settlement on the entire North West Coast.

Hanna continues his explorations and, at Ahousat on Vargas Island, visits Chief Cleaskinah, who will subsequently be known as "Captain Hanna" as a consequence of an exchange of names in accordance with local custom.

His success in trading for pelts is limited, and before he is able to make a planned third voyage to America Hanna will die, shortly after his arrival in Macao, in early 1787.
