What does five short blasts signal under international and US Inland Rules?

• A. "I am passing you on your starboard side"
• B. "I am unsure of your intent"
• C. "I intend to overtake you"
• D. "I am altering course to port"

Answer: (B)

Five short blasts of a horn are a sound signal used under both international and U.S. Inland Rules to communicate a situation of uncertainty. Specifically, this signal is often interpreted as a warning that the signaling vessel is unsure of the intentions of another vessel, especially in situations where the navigational situation may not be clear. This could occur in scenarios such as restricted visibility, heavy traffic, or when the helmsperson cannot ascertain the maneuvering intentions of another vessel nearby. When one vessel makes this signal, it prompts the other vessels in the vicinity to clarify their intentions. This communication is crucial for maritime safety, allowing vessels to avoid potential collisions and navigate safely in uncertain or congested conditions. Understanding this signaling is essential for effective communication and safe sailing practices.
