Tarptent Moment DW wind strength

Here is what Henry Shires( owner and tent developer of Tarptent)had to say a couple days ago on another THREAD .

Henry T.,

I own a TT Moment DW, as the linked thread shows. And I feel it IS very wind-worthy when the main arch pole is guyed out from the factory guy points, the fly staked down with the fly hem stake loops and the ends guyed out from the factory guy points midway up the fly. And this is without the X-ing pole.

So yes, I always carry 4 prepared guy lines (color coded for sides and ends) and yes, I have experienced steady 30 – 40 winds in the Moment DW with no problems at all – properly guyed out as described above. This means I also saw no main pole deformation in gusts that the weather service said went up to 55 mph.  In comparison to the similar Hilleberg Akto the Moment DW is more wind-worthy by far.

But since Henry has said the Moment DW is not as “wind-worthy” as the Rainbow I guess I’ll get a heavier main pole from Tentpole Technologies, as I did for my Scarp 2. After all, Henry is the designer and he should know.

Eric,

Yes, additional staking is the way to go for stiffening up the Moment DW.  When I made the comparison statement, I was referring to “out of the stuffsack” performance.  The Bowfin 1 with two stakes is stronger than the Moment DW with two stakes because of the relative better arch support inherent in the Bowfin 1.  There’s no doubt that arch pole and perimeter hem guyouts make a huge difference for the Moment DW. The Bowfin has comparable additional guyouts on the arch sleeve, hem, and struts.  The Bowfin comparison to the Rainbow is really about the relative symmetry / asymmetry difference with the Bowfin better able to handle wind from all directions and the Rainbow not as able when wind hits the steeper, flatter back wall.

Thanx that answers my question

Worked fine for me:

Yep Alex, DW main pole guyed out is all it takes in most situations.

As I said before in the Bowfin thread, I think I’l buy a heavier duty main pole from Tentpole Technologies since being enlightened by Henry’s comments on its vulnerability in high winds. With the factory main pole if a guy stake suddenly pulled out the main pole could collapse in a heavy gust.

A heavier main pole, such as I have for my Scarp 2, must have some pre-curved sections to get it into the needed curve. For the proper amount of pre-bending Tentpole Technologies asks you for two measurements: 1. pole tip-to-pole tip distance on the ground when the tent is pitched 2. maximum height of pole arch from the ground

BTW, I always carry all 4 guy lines in my tent sack. It’s a lot of insurance for the weight.

Eric , are the perimeter hem guy-outs standard on the Moment DW or did you sew them on? Where are they exactly?

The Moment DW (now) has perimeter hem loops standard. They are located halfway between the vestibule zipper and end strut — so, 4 total.

Thanks, I’m going to hand sew something similar onto my single wall Moment.
