Sheedy, Jack and Coogan, Jim. Cape Cod Voyage: A Journey Through Cape Cod's History and Lore[permanent dead link], East Dennis, Massachusetts: Harvest Home Books, 2001, p. 19. The "lower" Cape is the northernmost part of Cape Cod, while the "upper" Cape is to the south. These directional terms were determined in seafaring days by the prevailing westerly winds, which were of paramount importance during the time when sailed boats were a primary form of travel. A boat sailing south-to-north on Cape Cod Bay would have the wind at its back, and was thus traveling "down", while the opposite was true of a boat sailing north-to-south.
