Through the years, the wish to mark other seagoing milestones has given birth to certificates for all kinds of distinctions. Most of them are variations on the shellback theme; they document, typically in salty language, passing certain places for the first time. Some of these time-honored traditions that have come to light include:

Crossing of the Arctic Circle (66-32 North latitude). Also known as the "Northern Domain of the Polar Bear" or "Blue Nose."
