I was wondering why the Bozeman Mountain Works Stealth 1 PRO (7×9) doesn’t have either beaks like the Golite Cave (see http://www.golitestore.com/store/NS_proddetail.asp?number=SH6000) or closed ends like the Gossamer Gear Spin Shelter (see http://www.gossamergear.com/cgi-bin/gossamergear/Spinn-Shelter.html).
Surely these features would stop wind blown rain from entering the shelter?
Also, are open ended tarps meant to be pitched side on to the wind, which would block wind blown rain? Or are they meant to be pitched parallel to the wind, which would cause rain to come straight through the door? A pitch parallel to the wind would resist higher wind speeds since the tarp provides the least resistance to wind blowing straight through it but it would also cause rain to enter the tarp.
Help would be appreciated!
