"is it almost 12 feet from the bottom front to the hatch hinge?" That's right, from where the front curve meets the lower edge (you can see the transition point) back to the hatch is 11feet 9 1/4inches. It'll be a little less without the lower curved front but it will still be more than 10 feet. You could run the sheet forward from the hatch and then add another short piece (at least 12") for the lower front and then run a piece of flat trim molding cross wise over the splice. I've seen tears this way and it's un-noticeable.
Have a good day, Gage
Remember 'Teardrop Time'.......Take your time, you don't have to have it finished NOW.
