Same here...I'm thinking xl tarp- has anyone used one? Can you actually get 2 hammocks under it or is it a logistical nightmare?
I've used one for years, excellent bit of kit and yes you can easily get 2 hammocks under it. Also consider the 4x4 which has even more coverage (+2.5m2) and is better for some configurations. 3m coverage end to end is enough for hammocks but 4m is certainly superior. Also a square is easy to go diamond, tarp tent or 3 sided tipi etc. OD was standard but new CB is very nice. You can easily turn back an edge if you don't have room for a 4m span.
