A friend of mine asked me to build a Hammock for him. I have a WBBB1.7 and he was impressed, and thought that it would been nice to be off the ground when we go camping. HERE IS THE ISSUE: I need to make a hammock that will support a man who is 6'10 inches tall and 550lbs. Does anyone have any suggestions as to how much ripstop nylon i will need? Layering tips? The webbing i will need for suspension? Thanks in advance for any tips, ideas. If anyone has made one to support this much weight please post a photo of it. Thanks
