"a sort of Flying Dutchwoman"

This refers to a legend in Cape Town, South Africa. The Flying Dutchman was a ship from the Netherlands that attempted to go past the Cape of Good Hope at the southern tip of Africa. It was caught in a storm and destroyed, yet people say that you can sometimes catch a glimpse of the ship as it continues to fight its way to the East.

The name has been popularised in recent pop culture by the film The Pirates of the Caribbean: At World’s End, as the ship that belongs to Davey Jones.
