I like having my tarp about 2-3 feet longer than my hammock, but I am weird about getting wet.
I agree. That's why Claytor's rectangular tarp is 13' long. The hammock is about 9.5....you wouldn't want it any shorter. I'm thinking about ordering one. At least then I'd have a choice depending on the weather forecast. The rectangular tarp with it's extra coverage sure would be nice on a rainy weekend.
