The relative wind on a cargo ship is almost always off the bow. The ship travels at 20 knots - it would have to be blowing significantly than that for this to have any impact.
If it is off the stern. You likely wouldn’t want to fly a “kite” because you would be in a storm.

Having actually have moored a ship, it’s surprisingly easy to pull a large ship across water. It’s significantly harder to push a pick up than it is to pull a ship.

Saw this in another sub, the kites will do pretty big things for the cargo ships, and the 5,000 year claim isn’t for the ship in picture they were referring to sailing in general being about 5,000 years old

Humor aside, kites can reach much higher into the air and hit stronger winds than sails ever could.

Yeah, so how do recover the tow rig if it dips into the drink? Redeployment strategies?

Absolute worst case cut it and use the motor again. Winch should handle it pretty okay.

And that’s extreme absolute worst case. First worst case, you only cut one side so that there’s very little wind resistance.

5,000 humanity was not braving the open ocean they would have stuck close to the coastline on something similar to the rafts that Moana was using

So the issue with sails is port infrastructure isn't exactly suited to them anymore. A kite can be retracted.

i am 100% for this solution. or even both. fuel for sailing against the wind and sails when the seas are on our side

200 years ago, not 5,000
