Was all ready to glass my deck tonight and the glass is only 122" long. That is 76" too short or >6ft. I've read the section of my manual that discusses cutting into two triangles. But that seems to be specifically for the MC 13. I can't quite figure out how I can cover the side decks, the fore and aft decks with thsi. Can you other MC 16.5 builders confirm how much fiberglass cloth you received?
