TT Scarp how strong is it ?

Impressive pole setup, and a nice long peg in good ground.

All parts of a shelter have to work together to create overall stormworthiness.

With so little 'give' in the hard part of the structure, the seams and fabric will be under a lot more stress in sudden gusts of wind.

What is the fabric weight?

It's the standard 1.3oz silnylon.

Now give me 20 pushups!

…based on that prone position I would say that you may have taken 'loving your tarptent' to the next level….

;)

This was prompted by reading about poles snapping under wind or snow load. In my very limited experience that happens a lot more often than fabric failure , but I am only guessing.
In fact the last pole failure I remember reading about was on a pyramid shelter.

Franco,
So that's what you look like while bowing to the TT god.

Where are those photos of the Silnylon Sublite that took a 12" snow load. Some stitching failed but everything else held. Henry revised the design to strengthen the failed connection.

Denis
You are right, the stitching failed on that one but of course it was not designed to take that load. On the other hand, there is a set up for the Scarp that will take that and more.

I have had poles break under a very high snow load (+ downwards wind – bad position), and I have had guy ropes fray on the stakes and break, but I have never had a fabric failure.

Cheers

True, a hex3 in fact, in the UK. We get some unpredictable weather over here. :-/

I'm sure the 1.3oz material is correctly specced for the job. Perhaps one of our failings over here is that we expect gear to last forever. Nylon does embrittle with age.

"Nylon does embrittle with age."
Now you have done it, that will get the Aussie Roger going.
What really amuses me about some folk over there is how on one hand they rave about shelters like the Laser Competition but but on the other dismiss the Scarp because " it just can't take the weather"
Of course many of those comments come from people that don't even know what the shelter looks like let alone having tried one.
If HS had sold that design to Terra Nova or Lightwave , and made it out of a green silnylon by now the forums there would be clogged with rave reviews *…
Franco
Yes, just my opinion
* In my trade, camera retailing, I was often amused at how differently people perceived exactly the same product (cameras,lenses,flashguns) according to the brand stamped on it.
Much easier to sell a Nikon/Minolta/Olympus (made by Samsung or Goko ) than the Samsung or Goko equivalent. True example.

I have yet too use my Scarp. Cant wait. Reckon in the UK it will be fine. I have one concern and it is not the strength. It is the gap between the bottom of the flysheet and the ground on the porch with out the adjustment strap which allows you to pull it down tight, which the other porch has. I am concerned rain could be driven through the gap which is several inches?. I will find out in the hills soon hopefully. The Scarp is great with a fast stable pitch. The inner is massive for one and could be smaller in width and save weight as well. Superb build quality and design.

Martin
I have been looking at that adjustment strap because it does not work well for me, but I have a temporary work out and plan to add some shock cord to it as I also plan to put one on the other side as well .
( just tested the strap and is working at the moment.. ) I prefer using the shock cord so that it allows for shrinkage or stretching of the material.
The bathtub (silnylon) is fairly high (6") and that fabric is somewhat splash resistant, it can hold drizzle without a problem. ( not sure how it will work when dirty)
An easy way to increase the floor height is simply to clip the outermost inner connecting point, one ring in, that gives you about 9" of floor height and still more than enough room for the mat inside.
(as an added bonus it pushes the floor a bit further away from the side)
Franco

Good tip. I would like to some photos of the shock cord arrangement you mention. I reckon it should do OK in bad weather Chris Townsend said he has used it in bad weather in the UK. I am looking to see his review on it. As for me I need to get it on a hill.

This thread could easily go OT here, but I'm confused at what you're trying to get across here Franco. Surely if HS had sold the design to Terra Nova or lightwave, he'd be open to being sued by the Scandinavian company which originated the design.

Prior art and all that.

Henry has built a great reputation for quality tents in the U.S. I'm sure that if he wants to break into the European market, he'll do so in his own time, under his own name.

In the meantime, if Terra Nova or Lightwave think his enhancements to the original design make his version better than theirs, I'm sure they'll feel free to shamelessly copy them.

> Surely if HS had sold the design to Terra Nova or lightwave, he'd be open to being sued by the Scandinavian company which originated the design.

Roger, this comment is completely wrong. Get your facts straight and understand what constitutes a design. If you bother to examine the Scarp and also the design by a certain "Scandinavian company", you'll see that the Scarp 1 is fundamentally different at the corner supports. The only thing it shares is the transverse arch pole–an element which said company did not invent and did not patent. The Scarp design is patent pending.

Jut for the record, we have no interest in selling any designs to anyone.

-H

Henry, my apologies if I'm wrong. I thought from a previous thread that the scandinavian makers tent also had inverted V supports at the corners.

Are you taking out a worldwide patent or a U.S. patent?

Roger, "prior art" is only relevant to issues of patentability, not infringement. Not applicable to the scenario you lay out.

Also, no such thing as a "worldwide" patent, only multiple national filings in however many countries one chooses (I guess Hague registered designs, EU/EPO regional, and other hybrid approaches are qualified exceptions).

Too much armchair lawyering around here. Talk about gear!
