About to redo a couple of South Bay Boat navy covers with Pat McCarthy of this site and we are looking at the material purchase, about three yards per boat. Will not replace the original mid-weight canvas fabric from 1982, but trying to decide on cordura vs. sunbrella -- or other options for the replacement. There are a number of discount materials on ebay, so it looks like it is a matter of preference...without provoking any theological disputes, and understanding we have some real pros on this site, anybody got any advice for the best material for a cockpit cover that will fold down and out of the way, but be used during the season and then stored inside the boat under a fiberglass cover in the off-season? Thanks, Rufus
