Well, I'll go straight to the point. I've seen a lot of English speaking people giving genders to objects through the years and it seems to happen only with special objects to the person. I was wondering these days how do they know about "object genders" since, as far as I know, it's all considered as "it" (gender neutral, different from "he/him" and "she/her"). In Portuguese, we would know like when I say "O carro" or "A casa", but in English, it's all "the".
For example: After finishing polishing your car you say/think "She's a beautiful girl" (or maybe "He's", I don't know).
Another example: After restoring an antique tool you say/think "This old boy is ready to work" (or "girl", that´s the point).
I learned from movies (yea, I'm talking about the remake of Stephen King's "It" - 2017) that boats are usually called as "she", but I don't know if that's true too and if there's a specific gender for each kind of object.
I hope you guys can help me,
Thanks in advance!
