I think about docks. I can't help it. I think it's pretty, but it's such a noun name to me.
Marine always strikes me as odd, because I've got family in the US
Marine Corps so it tends to be used as a generic name often for men to encourage them when they're doing something tough, "C'mon
Marine", but also because it's a descriptor for marine biology. I do think it's likely nice in French though, as it is a nice sound.
