Cant you just say "the waves"? Calling it "her" once is fine, but four times is creepy.

It's weird to say 'her' once and then switch pronouns. But I hear you. You're picturing me with a peg leg. :)

Here's an HNer who knows that gendered pronouns exist for many inanimate nouns, and thinks that it's okay.

edit: Just to make sure I'm understood, I mean to say "I think it's okay", not to mock the OP who used the pronouns. More directly and non-sarcastically: "Using 'her' for bodies of water is not wrong".
