Hi fellow builders!

I am working on filleting the inside of the boat and with that trying to figure out the fiberglass for the cockpit...the manual says to use the 6oz. glass. Manual also says that were we supposed to get 3 sheets of fiberglass, but we've only got 2 - one 6oz sheet at 10yds, and one 4oz sheet at 4 yds. I assume we're supposed to cut the 6 oz sheet to fit the floor of the cockpit? The wording in the manual is confusing us!

Thanks
