The short answer is someone designed it specifically to demonstrate calibration across different printing conditions and it took off in no small part because it’s cute and can serve as a filament sample.
I think it’s because Benchy has a crazy amount of changing surfaces and is easily printable with or without supports, scales better, and doesn’t take terribly long to print.
How did tug boat become the standard test print? Wouldnt car or eifel tower have the same curves/arches/height for all the test things?

The answer isn’t glamorous, “because someone made it, and it works well.”
Also the “3DBenchy_Broschure_3DBenchy.pdf” file it comes with is helpful.
Nobody knows.
