Wilderness Systems replacement hatch cover for kayaks circa 2003 to date. Made of dual density rubber and fits over the raised hatch opening like a Tupperware lid. Has internal tie-off for a leash. Raised hatch lip on deck must be 8 inches outside diameter. Cover is 8 3/8 inches outside diameter, 7 3/4 inside diameter. While this is NOT a Valley Canoe Products hatch it is an acceptable fit to the Valley 8 inch rim. Also an acceptable fit for kayak Wilderness Systems models Cape Lookout and Pamlico, circa 2000 to 2004, outfitted with the discontinued Compass Rose Hatch Cover.
