According to long-standing maritime tradition, the gaff is the position of honor on a ship, and thus is where the U.S. Flag should be flown. Yachting organizations and nautical parks, following nautical tradition, erect land-based, gaff-rigged flagpoles and fly the U.S. Flag at the gaff as well: The gaff is considered to be the position of honor. This arrangement is used by several municipalities with parks located by the water, including the Village of Southampton.
