The oddity, explained
Why is Joan Margaret unusual?
Joan Margaret appears here because the approved source classifies it as maritime. The source describes it as Joan Margaret was a schooner built in 1948 and lost on 18/03/1963. A freak wave hit the boat, snapped the anchor cable, and it went aground. 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.
