"In order to survive for some twenty-five years, the Beans would have depopulated the entire southwestern region of Scotland" - wikipedia (citation needed)
While it is not clear that any small craft were used to effect this depopulation, the Beans did live in a cave by the sea. Skin on frame construction techniques were well known to the Scots.
