We all know nylon tent canopies stretch when wet, maybe by as much as 3%. I currently have a TT Moment with a few mods. Some are to combat the effects of silnylon's stretchiness when wet, and some just to batten it down in high winds.
Storm & Safety Mods
1. Quick set-up snap attatch TripTease guy cords with small TT type line tighteners (For the two factory tie-out loops on the hoop sleeve.) Mainly for staking out in high winds.
2. Top 1/2 of the canopy coated end-to-end with 5:1 ratio (by volume) odorless mineral spirits and GE silicone caulk. Seems to have less "wet stretch" after I did this.
3. Four perimiter loops of grossgrain ribbon on the hem for staking out in high winds.
4. And finally, I ran my optional "crossing pole" INSIDE the Moment and back out each end for a lot of canopy support, especially if I might get snow. That's the only time I'd carry the extra weight. It does keep the canopy from sagging when wet.
I'd like to somehow run my end tensioning lines inside so I could re-tension it without getting out in the middle of a storm to do it. Maybe rig it around the end stake and back inside… I've already got the hole in each end for my internal crossing pole to do it. Hmmm, micro pulleys…
What are your mods or tricks for keeping your tent taught when wet? Or is your tent designed with enough hoops that you never worry?
