I have the Kelty Noah 9 and the 12. I use the 12 to cover two hammocks and it does a great job. The Noah 9 was on sale and I got it for friends to use with one of my other hammocks. I have used the 9 and like it, but it does not rig up rectangular only diagonal. It is still a great tarp and has plenty of coverage. Definitely worth the small price I paid for it.
