This article sucked by the way. It said "Any sailor worth their salt can tell you that a boat can travel faster than the wind by cutting zigzag patterns; that's called tacking."
Any sailor worth their salt knows that is not true at all. This practically destroys any credibility on this topic by this author.
You sure? Take a gander at this article https://en.wikipedia.org/wiki/High-performance_sailing
You’re right in the sense that tacking is not the word for sailing faster than wind, but it is true that sailors can tack faster than the apparent wind, and that professional sailors know that. The “apparent” part is an important part of the discussion that the quote didn’t include or clarify, but would be implicitly understood by the saltiest of them.
