Longer guylines on Lanshan 2 Pro

The last podcast episode on ultralight shelters in inclement weather has reminded me that some weeks ago I bought two 50 ft bundles of Paria Dyneema Guyline to replace guylines in my Lanshan 2 Pro tent. I’d rather have longer guylines, so that I would manage to pitch it also in situations where I can’t use stakes.

I read the Guide To Alternative Shelter Anchors by Mike Clelland!, and I was thinking of replacing all current guylines in my tent using Andrew Skurka’s system.

I have some doubts though, particularly at the corners. I could simply attach longer guylines to current short ones. At mid-level attach points on the panels, and at the apexes though, I think I have no option other than replacing current guylines.

Here you can see a standard pitch for the Lanshan 2 tent, so you can get an idea about its attach points.

It has 4 corners, plus 2 ground level tie-outs on the two doors, plus 2 additional ground level tie-outs on the head and feet panels, for a total of 8 ground level tie-out points. I would use a length of 5 feet for those points.

There are 4 other cords at the corners, though. Lanshan refer to them  as positioning cords. They are attached to the bathtub (not the flysheet), and their main function seems to be helping in positioning the corner stakes for a standard pitch. So I don’t know whether I should put longer cords there as well, in order to have more flexibility at staking the buthtub corners. But is it really needed to stake the bathtub?

Then there are 2 apexes, and I would use 10 feet guylines for each.

Finally, for the two mid-height tie-outs at the head and feet panels, I would use 7 feet guylines.

Do you think it’s ok? What are your suggestions regarding the 4 guylines at the corners of the bathtub?

Thanks!

I haven’t been able to listen to the podcast yet so this may be redundant. A couple of thoughts:

You can’t pitch a mid with substantially longer guylines and expect a good pitch. The line typically needs to be an extension of the seam. You won’t get a good pitch tying off to a root 3’ away, for example because you will be pulling out too much and not down enough.

That said, you could add some “rock loops” to your existing guylines in order to have some extra length for tying off to rocks, roots, etc. I’ve done this in the past with 18–24” of extra line with a half hitch on a bight or bowline on both ends. I think it’s simpler to just have add extra length to your lines.

I routinely ignore guying out the bathtub on various shelters. I’ve never noticed a problem with it but YMMV.

You are referring to the corners, aren’t you?

What about apexes? Would much longer guylines be a problem as well?

Yes, I was referring to corners.

The geometry problem doesn’t occur with an apex, as far as I know.

I thought I would need much more line than 18-24”. Would it be enough for something like this?

Perhaps I should have specified that I’ve used this approach with a tent/tarp equipped with Linelocs. I mostly used this approach back when I had a Duplex and I’d use the main guyline loops when using a stake and then use the rock loop going to a smaller rock (a chock) with one or more larger rocks on top. Zoom in close and you can see it in this shot.

The “rock loop” is knotted to the stock guyline, or directly to the tent webbing, or the linelock hole?

I know this should be easy, but I’ve read somewhere that additional thin lines can cause some damage to webbings or cords when there is wind, and I’d rather avoid any inconvenience.

 

Thanks

On the Duplex I had guyline through the lineloc terminating in a loop (half-hitch on a bight or maybe a bowline). The rock loop was tied through that loop. When I used a stake the rock loop was ignored.

Like I said earlier, I decided at some point that it was easier to just use longer lines in this application.

I agree that lines can break but I typically use fairly durable line (Lawson) and with that extra length I feel like I can improvise something if needed. I carry some extra line (~10’ of MLD’s 1.5mm orange line, similar to your Paria line) and inspect my guylines every now and then.
