Specifically, I'm wondering about securing the hammock/tarp to a SLS of coated (not sheathed) Spectra (either Cortland Plasma or Amsteel Blue) by friction hitches, with attachments of the same (or another material if necessary). I'm also thinking to use a friction hitch to tie back from the tree slings/huggers. Is it possible with any of the following (or others)?
Distel, Michoacán/Martin, Prusik, Icicle, Adjustable Grip Hitch........
Quite frankly, I'm skeptical of friction hitches with any synthetics. Sheathing is (in part, at least) an attempt to overcome the inherent slipperiness of synthetics but comes with it's own shortcomings. Friction can be increased by increasing the contact area and/or by increasing the pressure between the two contacting surfaces. Unfortunately, increasing area tends to decrease
pressure, so getting a net gain becomes a delicate balancing act. Delicate balancing acts are not my favorite entertainment on dark and stormy nights. That said, I do occasionally use friction hitches but most often as the final tie-off of a trucker's hitch. Hopefully, those with more experience using friction hitches with synthetics will chime in here. Fortunately, your post has already gotten the attention of Grizz, one of the forum's most authoritative on the topic of knots.
