Ruby

The oddity, explained

Why is Ruby unusual?

Ruby appears here because the approved source classifies it as maritime. The source describes it as Ruby was a ketch built in 1871 and lost on 20/07/1890. Thought to have foundered, no trace discovered. Heritage Atlas treats that specific classification-and-description combination as the oddity; the score is a comparative discovery signal, not proof of mystery or the supernatural.

Evidence and further exploration

The coordinate, category and description remain tied to the cited source. Comparative oddness helps discovery; it does not add facts that the source does not provide.
