The researched reading
An oceanographic marvel with a sailor’s legend attached. Calms and drifting derelicts explain the ghost-ship image.
| Explanation | Weight | Why |
|---|---|---|
| A known natural phenomenon | 62% | The Sargasso Sea lies in the subtropical high-pressure belt (the horse latitudes), where winds are light and sailing ships could be becalmed; its floating Sargassum weed is thin and cannot trap a ship. Real hazards were calm, thirst and scurvy, not the sea itself. |
| A hoax or fabrication | 14% | Fiction and later Bermuda-Triangle books spread the image of weed-locked ghost ships. |
| Something known, misidentified | 12% | Derelicts drifting into the gyre’s slow current, a real phenomenon, were read as ships “captured” by the sea. |
| Perception, memory or mind | 8% | Sailors’ fear of calms and of the weed, from Columbus’s crew onward, fed the legend. |
| A poorly understood natural phenomenon | 2% | Nothing unexplained is documented. |
| Secret human technology | 1% | Not relevant to the legend. |
| Genuinely anomalous | 1% | No case needs it. |
Official position: No official finding; oceanographers describe a calm, nutrient-poor gyre of great ecological importance.
