They do. My daughter has two - a Viking ship on one bicep, and a bomber on the opposite forearm. (She's a very militant girl, just graduated from Gunnery school and now a firearms instructor.)
And it's not because she was deprived of religion and transcendence and all that ... church-going, Bible-reading, homeschooled from 4 to 17, knows more Scripture, Greek and Latin classics, and world literature than anyone she ever meets. She just wanted a couple of tattoos, apparently because it's a sailor thing. She wants a motorcycle, too.
My sailor son Will just got three, at least one was a Sailor Jerry design.
How big a ship is she on?
