By Gerard MeunierOn our way home after cruising the Erie, Rideau, Chambly and Champlain canals and the Thousand Islands area, we anchored in Mile Hammock Bay on the Intracoastal Waterway near Camp Lejeune, North Carolina. We ate dinner, admired the sunset and were watching TV when something felt wrong. Cat House, our 40-foot power catamaran, was tilting forward. I checked the forward cabin and stepped in several inches of water on the starboard hull floorboard. We were sinking.
