Frederick A. Hinman removed sunken vessels “obstructing or endangering navigation,” including the barge Albemarle near Hog Island lighthouse in Virginia, the schooner Maria and Elizabeth near Cape Charles lighthouse in Virginia, the schooner Tarry Not near Craney Island near the mouth of the Nansemond River, the schooner Anthea Godfrey in “Lynn Haven Roads, Virginia” [sic] (which was destroyed by explosives after having shown the wreck and cargo were valueless), and the steamer Concord, which was burned and sunk in the Pamplico River near Washington, North Carolina.
