I am strongly considering selling my diy Hex tarp with catenary curves. It is 110" long by 72" at the at the inside of the cat curve from side to side. This gives plenty of coverage. and I was ready for any weather that came my way. The tarp has had its seams sealed and has only been used 3 times and pitched 2 more than that. Tarp alone comes in at 11oz.
I would also include a zing-it continuous ridgeline with a titanium dutch hook on one end.
I just want to go a bit longer.
PM me an offer if your interested.
