word usage - Can a ship or a car be a "he"?

In English, especially in a poetic description, ships and cars are referred to as "she".

Maybe their owners compare their beauty and elegance with those of women, but what if a female owner wanted to describe her yacht or car?

Would she also say, "She is a real beauty", or it might be "he" then?

Does the choice of a pronoun depend on whom she is giving the description of it to — a man or a woman?

What about a man-o’-war or a merchantman? Being ships, are they also referred as "she"?

P.S. There's a post on the use of "she" in reference to ships, but there seems to be no answer to my question there.

P.P.S. My question wasn't pulled out of a thin air. I came across a book by a prominent Russian linguist, G.Veichman, written in 1990, (Novelties in The English Grammar is my translation of the title), where I read that the rule of personification of vehicles may be added regarding a female owner talking about her car using the preposition "he". Period. No further explanation or reference examples.

Answer

There is no law that one cannot use masculine or gender neutral pronouns to refer to ships and other things that are normally referred to by feminine pronouns.

For instance, if a female owner wanted to name her yacht a man's name, paint that name on her yacht and refer to this yacht as he, there is no language police that can stop her.

Besides that, Is your vehicle a 'he' or a 'she'? quotes a survey that says

Nearly half of drivers think their vehicle has a gender, with 60 percent of vehicles viewed as female and 40 percent viewed as male. Of those with a gender, vehicles in Southern states are more likely to be female, while autos in the Midwest are more likely to be male [my emphasis].

There is also a current commercial on TV for an insurance company, and it starts off with a woman who has named her car 'Brad' (a male's name)...

At any rate, this question is not, to me, about what the convention is, but whether or not it is possible in English. And of course it's possible. And I see no reason to discourage a woman, or man, from doing so.

Hurricanes used to always be given female names. Now during each hurricane season, the names alter between male and female. So it's not like there is absolutely no room to maneuver regarding this subject: for whatever the reason may be, it's possible to incorporate change.
