Key Points
-
Debate on Searchlights:
- There was a debate both in 1912 and more recently about whether a searchlight could have prevented the Titanic disaster.
- Warships in 1912 were equipped with searchlights, but merchant ships like the Titanic were not.
-
Night Vision vs. Searchlights:
- The article argues that searchlights would not have guaranteed safety because they would impair the crew’s night vision.
- Night vision is crucial for detecting objects in low light, and searchlights would disrupt this by overwhelming the sensitive rod photoreceptors in the eyes.
-
Technical Details of Vision:
- The retina has rods (sensitive to low light) and cones (detect color but need more light).
- Effective night vision requires time to adjust to darkness, and any white light would reset this adjustment period.
-
Practical Limitations:
- Searchlights could blind the crew and officers, making it difficult to see hazards outside the beam of light.
- They could also interfere with the navigation of other ships in the vicinity.
-
Historical Context:
- Merchant ships were not equipped with searchlights for transatlantic runs due to the potential hazards and the lack of strict regulations governing their use.
- The Titanic’s crew relied on their eyes and the clear weather conditions to detect icebergs.
-
Speed and Decision-Making:
- The Titanic was travelling at full speed through a known ice field, which was a calculated risk taken by Captain Smith.
- Reducing speed would have been the most effective safety measure, allowing more time to detect and avoid hazards.
-
Conclusion:
- The article concludes that the absence of a searchlight was not the primary factor in the disaster.
- The key issue was the ship’s speed, which did not allow sufficient time to react to the iceberg.
