Question: is a center seam on a cuben tarp necessary? In other words, if I wanted a cuben tarp that was 3 panels of cuben wide (instead of 2) by 12 foot long (so, in effect, about 12×12), would that be okay, or would there be issues with not having a center seam?Feb 9, 2013 at 4:19 pm #1952680

I know of at least one company that makes their larger sil tarps using 4 panels, so I don't sew why it would be an issue to use 3.Feb 9, 2013 at 4:26 pm #1952686
With four panels you'd still have a center seam. I'm wondering if that center seam is necessary.Feb 9, 2013 at 5:09 pm #1952696

If you don't want a catenary ridgeline, I think you could put the seams anywhere (on the diagonal, if you like). If you want 12' x 12', I think two seams sounds like a good idea.Feb 9, 2013 at 10:58 pm #1952778

if you were using it as an A-frame set up, and the 'ridge-line' was going to be the main guy-out point through the middle of a panel, then i would probably make a seam. not a seam as such that uses 2 panels joined, i would look at doing a multi-layer folded/ taped seam, just for added strength. sometimes the seam can be structual, the strongest point, sometimes it can be the weak link
i dont know anything about it though, but thats what all my expirence tells meFeb 10, 2013 at 7:46 am #1952849

My memory is a little fuzzy, but seems like Hammock Gear made a large cuben tarp for a customer that sounds really close to what you are talking about. I remember it had two seams. You might search around Hammock Forums or email Hammock Gear for more info.

ryan i think that was the original plan w/ the tarp (3 panels of cuben). however i don't know if stormcrow ended up going that route. here in this vid he just added a foot onto the bottom of his normal tarp. he starts talking about that at 8 min.
maybe he's changed it since then though.Feb 10, 2013 at 12:21 pm #1952928

How about running a ridge line inside the tarp? That way you add tensile strength to that dimension without worrying about seams ripping or waterproofing issues.
It also makes a nice place to hang a light, glasses, or gear to dry.
Using a midweight of Spectra would add only a few grams of weight to the set-up.Feb 10, 2013 at 12:49 pm #1952937
