Engineering360: "Video: First Seawing kite system to set sail"

62mph seems a bit fast to me. A video of the sail in operation would be helpful.

I agree. 62mph seems high for the ship, but perhaps is the wind speed? Clarification is needed on that stat.

Re-reading I think they meant that the kite reaches a speed of 62mph following it's "figure 8" trajectory. I've flown kites that are maneuverable and they can move quite fast in a slower wind. They pull like hell when they do, so this would be a good number for this application.

Normally a powered vessel gives way to a sail vessel. What is the case here now, as both are classed as sail? This will cause some confusion and reset the sailing rules world wide.

A bit of a catastrophe if the chute lets loose and fouls the props. But I am sure this is catered for in some way.
