I am considering making Griz Beaks for my hex tarp. In the course of planning this project, I stopped and asked myself, "Why do these need to be waterproof?"
Since I don't have the answer to that question, I am bringing it to you all-knowng HammockForum members.
For example, consider nylon. Waterproof silnylon weighs about 1.4 oz/sy while uncoated nylon weighs only 1.1 oz/sy.
As I understand it, the intended purpose of a beak is to block the wind-tunnel that open tarps could experience. Regular nylon should do the job.
What about wind blown rain," you ask? I might be wrong but I think uncoated nylon (or spinnaker) would keep the hammock dry in that application.
So, what's the verdict? Can I be a gram-weenie and still have functional beaks?
