Q1: Why does the article refer to the Titanic as "she/her" rather than "it/its"?
A1: Per WP:SHE4SHIPS, the vessel is referred to with feminine pronouns. This is not to be changed without consensus. For discussion of Wikipedia's internal inconsistency and divergence with Encyclopedia Britannica's usage on this point, see Huddleston, Pullum, & Reynolds (2022), A Student's Introduction to English Grammar, 2nd ed., Cambridge: CUP, p. 14-16.
