where did this come from?

come about: To tack or change heading relative to the wind.

tacking: working to windward by sailing close-hauled on alternate courses so that the wind is first on one side of the boat, then on the other.

jibing: changing direction with the wind aft; to change from one tack to another by turning the stern through the wind; also spelled gybing.

I'm sure the USCG and the National Maritime Center who sets the standards for testing would be interested in that definition.
Notice that in describing the gybe it says to change from one tack to another. A tack is a point of sail representing which side of the vessel the wind comes from.
If you answered that a tack was a maneuver it would be marked as incorrect. Tack is a noun not a verb.

This is exactly why I decided not to become a sailor. (lmao) Can I still be a pirate?
