Look familiar?

Who needs AC boats when we make these. We got your wind.alberta clipper
While we in the northeast greatly appreciate Canadian generosity (especially with ), many of us would prefer, not to be impolite, that you keep your Alberta Clippers to your self.Who needs AC boats when we make these. We got your wind.
Stumbled upon this video yesterday...what do you think?
I don't see anything here breaking the laws of physics
Relative to the land, the air isn't moving. Water is moving relative to the land and the air. When the boat moves opposite of the water direction at the speed of the water current, it is not moving relative to the land and air.It seems that way when you look at the land, but the boat isn't sailing on the land, it's on the water.
Correct, but they would never just be sitting still relative to the land. If they were, then the current would start to pull them into the wind again. Once they get pulled into the wind they're sailing, building apparent wind which then keeps them sailing as they turn down to a broad reach again.When the boat moves opposite of the water direction at the speed of the water current, it is not moving relative to the land and air.
There is. Wind relative to the water. That's the same thing that makes waves anyplace else - a difference in motion between the surface of the water and the air above it. The water and the air don't care whether or not they're moving relative to some land mass that is yards or miles away, just their motion relative to each other.Sorry, but when I look at the water in the video, I say there is some wind....

Let's assume the current is a tidal current and not a river current. What happens at slack water? No current, no wind.There is. Wind relative to the water.

(For a bunch of sailors we all seem pretty concerned about the land... Take it out of the equation and this is all much easier.)
On that we can agree.Let's assume the current is a tidal current and not a river current. What happens at slack water? No current, no wind.
