It Looks Like Trimaran To Me

[Curmudgeon]

But it circumnavigated on solar power alone.

Solar-powered catamaran completes record-setting circumnavigation

A 10 million dollar boat to support 5.

Green?

Maybe I'm just jealous.

One may ask how green producing this amount of solar panels and batteries is, in the first place. If we externalise the ecological damage costs to China then sure solar panels are 'green'. So are batteries.

This is in no way a slam on the the original poster.

I consider wind driven boats to be solar powered since the sun is what causes the winds to be blow. A lot more "green" than this big expensive machine. I'll bet, too, that they had a diesel generator on there somewhere.

It is quite a feat but in my mind lots of people spend money on things just to say they could do it.

Expensive or not, this is the type of innovation and example the world needs. I suppose 10 mil is pretty cheap in terms of a custom 100' yacht.

By the way, I think its a tri too even thought that middle hull doesn't seem to get wet while not underway.

Actually, the spin of the earth makes the wind, not the sun, along with the presence of the atmosphere.
Some planets (gas giants like Saturn) spin so fast, they create winds up to 1000KM/H (The red spot is a giant hurricane, blowing for the last 10,000 years or so)

[SkiprJohn]

Thanks Blue Child,
I'll argue that it is a combination of the two. Certainly sea breezes that occur around San Francisco Bay are because the inland heats up during the summer via solar power.

Only two hulls are actually displacing water (aside from waves). I guess that a purist would still call it a cat. Either way- Its quite impressive.

I was always curious why the wind always blows from the east and never any of the other directions.

Actually, you have never heard of high and low pressure systems and what causes them?
