This is nuts. No sail, no engine. Just the currents. Incredibly impressive.

It's pretty neat.

What was even neater, IMO, was how, long before satellites and computers, they used to drop notes in bottles with the date, location, etc. and they would also collect and log them - and by accumulating all the global data over centuries they developed maps of the ocean currents, trade winds, etc.
