That's actually the reason I stopped riding foils in light wind in the first place.
A very long swim off the beaches of Sorrysota about 8 years ago (only went 100 yards, but took 1 hour) with a fully soaked 12m JoJo was enough for me.
I sold it within 5 minutes of hitting land to Rob Hassle and never considered placing myself in that position again.
I realize most kites won't re-launch in really light wind. But at least an inflatable can do as it's name implies.
I also realize that most ram-airs have sealed cells. So did the Jo-Jo.
It won't matter after ten minutes of soaking, I don't think. :-?
