Sure, I know sailing catamarans well (via Youtube vids mostly admittedly). But I switched drooling focus when these things started appearing- I suspect they will eventually displace many if not most other boat types (albeit not in my lifetime), possibly using hydrogen (not battery packs) as energy storage. Sunshine is not required if I understand it correctly. No wear and tear on the sails, not dependent on winds to go from point a to b, more like driving than sailing, except no pollution, no noise.
