      IMHO arcs launch so well because the angle of attack can be varied. Just
      don't turn them inside out treating them like an inflatable while lying on
      the water! A foil launching leading edge up downwind has tons of drag and
      very little lift because the bridal sets the AOA at nearly 90 degrees
      relative the wind. My experience is foils launch much better backward,
      flying on their brakes, from downwind.

      Could be any of a number of factors:
      No bridle (I'm sure when wet it adds more weight than you'd think, just like
      it adds more drag than you'd think).
      Tip battens (added weight, but maybe they help somehow).
      General shape (maybe the arched shape helps somehow).
      Flexibility of shape without bridles (don't know how that would help, but it
      The fact that mine was practically brand new at the time might be a factor.

      On the other hand, since I only tried it once, maybe I was just lucky. It
      seems the consensus is you never get good at relaunching an ARC because it's
      so rare to crash them. Anybody else have extremely good success relaunching
      ARCs in light winds?
