Question 7 RVR05 - Master of LT 100 GRT

The Correct Answer is C ### Why Option C is Correct: Option C, "when you can take proper and effective action to avoid collision," accurately reflects the definition and requirements of "safe speed" as defined in Rule 6 of the COLREGS (International Regulations for Preventing Collisions at Sea). Rule 6 mandates that every vessel shall at all times proceed at a safe speed so that she can take proper and effective action to avoid collision and be stopped within a distance appropriate to the prevailing circumstances and conditions. The primary purpose of maintaining a safe speed is the ability to maneuver and avoid dangerous situations. ### Why Other Options Are Incorrect: **A) when you are traveling slower than surrounding vessels:** This is incorrect. While reducing speed is often necessary, simply being slower than surrounding vessels does not automatically mean the speed is "safe." A safe speed is determined by numerous factors (visibility, traffic density, maneuverability, etc.), not just relative speed to others. In some situations (e.g., in a narrow channel), being significantly slower might actually impede traffic and contribute to a dangerous situation. **B) when no wake comes from your vessel:** This is incorrect. Wake (or lack thereof) is generally related to speed limits in harbors or environmental concerns, but it is not the defining characteristic of a "safe speed" under COLREGS. A vessel could be making a substantial wake yet still be proceeding at a speed deemed necessary and safe given the circumstances (e.g., in open, clear waters). Conversely, a vessel could be making no wake but traveling too fast for restricted visibility. **D) when you can stop within your visibility range:** This is a crucial **factor** used to *determine* safe speed, but it is not the complete or overarching definition provided by the COLREGS. Rule 6 requires a vessel to be able to be stopped within a distance appropriate to the prevailing circumstances and conditions. However, the definition of safe speed is broader, encompassing the ability to take "proper and effective action to avoid collision," which includes maneuvers other than just stopping (like turning or reducing speed). Option C captures this broader concept of effective collision avoidance action.
