Question 25
GLI08BOTH INTERNATIONAL & INLAND What is the duration of a "short blast" on the whistle?
AI Explanation
The Correct Answer is A
**Explanation for Option A (1 second):**
Option A, **1 second**, is correct because it aligns with the definition of a "short blast" as specified in the International Regulations for Preventing Collisions at Sea (COLREGs), which apply both internationally and on many inland waters. Rule 32 defines a short blast as a blast of about one second's duration. This definition is universally accepted in maritime navigation rules for maneuvering and warning signals.
**Explanation for Other Options:**
* **B) 4 to 6 seconds:** This duration is too long for a short blast. It is closer to, but not exactly, the duration defined for a **prolonged blast** (which is 4 to 6 seconds according to Rule 32).
* **C) 8 to 12 seconds:** This duration is significantly too long for any standard maneuvering or warning signal defined in COLREGs.
* **D) 12 to 15 seconds:** This duration is far too long and does not correspond to any defined whistle signal (short or prolonged) in the maritime rules.
