I just got the plans for my layout boat. They call for 10 oz X 60" fiberglass cloth. US Composites only lists the 10 oz cloth in 50" widths. They do have 6 oz in 60" wide, but I am not sure if this will be strong enough. I tried Raka but their website was not working. I figure that someone here should be able to point me in the right direction. The 60" wide cloth is to be used on the deck. Will the 6oz be strong enough? If not where else can I try to find the cloth? Any help will be appreciated.
