Ordered glass to cover the deck of my West river 180 (it an option) and they gave me a piece that was 3 yards long. Its wide enough that if I cut it in half it covers almost all of my boat, but i still need to use a scrap for the tip. Thats two seams and three pieces. If they had told me this is what i get when i ordered the deck glass option i would have paid the extra and specified 18' for a boat that is 18'. Some complaints but also some good things about CLC.
