I just wanted to share an intriguing guyline setup for a Tarptent Double Rainbow. I have the Li, but I assume it would work with the silnylon version as well.
I emailed Tarptent for recommendations on how to orient extra support guylines attached to webbing loops midway up either end of the arch pole. Henry Shires responded within hours (Thanks, Henry!) with an arrangement I never would have thought of (see pic below).
Maybe engineering folks won’t be surprised, but I was. I set it up and it seems very sturdy.
Here’s how Henry explained it: “That provides an inward compressive force on the arch pole.”
I’ll be taking it into the field. I’d love to hear people’s thoughts on this arrangement, and hear what your favorites are. My only concern is that the tent sides might rub against the lines in a high wind and get abraded.
