I'm quite fond of the little asym tarp that comes with the hennessy expedition, but I feel like it could use just a little more coverage in certain areas. I took the stock hennessy asym tarp dimensions : a parallelogram that has 99" long sides and 63" short sides according to hennessy's website. It also has a 132" Ridgeline on the diagonal.
I want to add two triangle shapes, effectively changing it to an asym hex tarp. I also wanted to cut the ridgeline back to 10.5 feet. This will be a fair weather, 3 season tarp. I'm looking for advice and opinions. Would it be wise to undertake this project, or would I be better off making a more standard hex shape tarp like a wilderness logics tadpole?
On the diagram, each box is six inches.
