Need to replace a missing deck board or floor cover that was probably made of teak wood. It is for my 91 Cimmarron 16ft fish and ski boat. I'm having trouble locating and willing to substitue a different material. It fits over an opening to a hole that would fit ski's or fishing poles and measure approx. 3ft by 1ft and a depth of approx. 3/4 to 1 inch thick. Can this part be purchased or will I have to cut material to fit? Note: last seen floating out to Bay St. Louis, Mississippi.
