Moran tugs running light up the North River usually singnal there is some action coming at the wallboard plant in Buchanan NY. Sure enough, a few hours after Mary Turecamo passed by Sunday, the 656-foot bulk ship Eastern Venture came through, Buchanan-bound with a cargo of Spanish gypsum, the principal raw material in wallboard. The plant gets about 12 ships a year and, together with the sugar refinery in Yonkers and a small oil products terminal in Peekskill, is one of the only remaining users of Westchester’s deep water shoreline for maritime transportation. In addition to Mary, Kimberly Turecamo also helped dock the ship.
