🔍 Key Concepts
• Rule 34 – Maneuvering and Warning Signals (sound signals for altering course, overtaking, doubt, and danger)
• Difference between maneuvering signals (1, 2, or 3 blasts) and danger/doubt signal (5 or more short and rapid blasts)
• Responsibilities when you are the vessel being overtaken and you do NOT agree that the maneuver is safe
💭 Think About
• Ask yourself: when you do NOT understand or do NOT agree with another vessel’s intentions, which signal are you required to use under the Rules?
• Which of these options clearly tells vessel "B" that you think the proposed overtaking is unsafe, instead of simply proposing your own maneuver?
• In both International and Inland Rules, what sound is used to indicate doubt or danger, not a specific course change?
✅ Before You Answer
• Verify in Rule 34 what one, two, and three short blasts each mean and when they are used
• Identify which signal in Rule 34 is specifically described as the danger or doubt signal
• Make sure your choice provides a clear, positive indication that you do not agree the overtaking is safe, rather than remaining silent or suggesting a different course change
