Familiarity: I've used it several times
I used this tarp for a 9 -day ocean canoeing expedition in South East Alaska. It is certainly waterproof, rain beads up and runs off better than anything I've used. The attachment points on the corners and in the center are reinforced with hypalon, which make them very strong, but when I set this tarp up in a "floating a-frame" configuration, the attachment points at the center of the ridge-line (in the middle of the 8 ft sides) are not reinforced, and I am already seeing some small areas where the strong thread used to sew on the attachment points is pulling holes in the fabric. I will be embarking on a 48 day expedition soon, and am worried that this tarp may not withstand the forces that I need to use to guy it out in strong wind and weather. I'll need a more heavy-duty material for my purposes. I can absolutely recommend it in conditions where heavy wind and constant rain will not be a concern.
