I live in New Orleans, and residents tend to call this city "she" rather than "it". Of course, this corresponds to the grammatical gender of the city's original French name, but I don't think that is the whole reason. To the extent that grammatical gender exists in English it tends to resemble the common/neuter distinction of Scandinavian languages rather than the masculine/feminine distinction of Romance languages. The old sailor who calls the ship "she" might also say things such as, "The wind, she blows, and the sun, he shines." This tends to be a function of anthropomorphisation; that is: he is implying these things have independent will and agency by using human pronouns.

Rubén Darío, Some English nouns have gender. There are masculine and feminine nouns for people. actor .......actress prince.......princess king..........queen bride........bridegroom Some nouns refer to both: doctor, lawyer, engineer, dancer, etc. You would refer to a doctor, for example, as he or she according to context. for animals: lion......lioness hen.....rooster gander.....goose fox...........vixen It would be acceptable to refer a lioness as she or a rooster as he. Most animals also have a neuter name: chicken for.....hen.......rooster cow or cattle for.....bull......cow. The neuter name requires "it" Ships and boats by tradition are referred to as "she". Maybe because sailors are so lonely. :) Pets are often referred to as he or she according to sex. Nouns that do not refer to a male or female are neuter.

While technically an "it", we often call things "she" and "he" to give a more familiar feeling. As though it has become slightly human in some way. For example, we would never call a new car "he" or "she" because we don't have a history with it yet. But you'll find people who've owned the same car for years may call it "he/she".

The Titanic was built in England and most ships that are made in England (or some other western countries) they are referred to as a "she" Take note that this is a traditional description and not official as most legal documents will refer to the ship as an "it" I do believe the reason ships are called "she" because ships mother and looks after her crew and keep them safe while out at sea.
