Help/Ideas Needed: Adding ridgeline tie-outs to WB Superfly for Bivy

[Stajdanley]

I am hoping you all can point me to a good tutorial or give me some ideas for a secure way of adding tie-outs to the under side of my Superfly's ridgeline. I will need two to attach my bug bivy to in order to give the ivy some structure and keep the netting raised off of my face when I need to go to ground.

My first idea was to sandwich the ends of my loop between two triangle-shaped pieces of ripstop nylon, sew that together and use some sort of silicone sealant to adhere that centered on the ridgeline, but I'm worried the stitching and thickness from the cordage will prevent it from adhering very well.

My other idea was to sew my loop into some grosgrain, then sew the grosgrain to my ridgeline, and finally seam seal the new addition. This one seems the most solid, but I don't have a lot of experience working with silnylon. I'm pretty worried I will murder my tarp.

Any ideas would be very much appreciated. Thanks!

How about utilizing a continuous ridge line under your tarp, which would allow you to drop lines down to your netting? Larks head to the ridge line, or prussic the drops.
That would prevent having to alter your Superfly. No "tarp murder" needed.

Thanks for the feedback. That has been my solution up to this point, but I am trying to ditch the continuous ridge line for this setup - I haven't been in a hard rain yet, but I worry the water will just follow the line under the tarp. Thanks again!

Not to worry. A simple short prussic or really anything tied to the CRL and placed at the edge of the tarp will serve as a drip stop.
With a taught and level CRL, there should be no downhill water flow. Usually whatever attaches your tarp to the CRL acts as a drip stop.
