BOTH INTERNATIONAL & INLAND What is the duration of a "short blast" on the whistle?

🔍 Key Concepts

• Sound and Light Signals – Navigation Rules, Rule 32 (Definitions) • Difference between a short blast, prolonged blast, and danger signal • Typical time range used on training vessels or simulators for a short blast

💭 Think About

• Look at the answer choices and decide which one is clearly too long to reasonably be called a "short" blast used in normal maneuvering signals. • Think about the signals for course alterations (one, two, or three short blasts). How long would each blast have to be so that three of them could comfortably fit into a few seconds? • Recall that a prolonged blast has a specific time range in the Rules. How does the duration of a short blast compare to that—shorter or longer?

✅ Before You Answer

• Verify in Rule 32 that short blast has a defined duration range in seconds. • Make sure you are not confusing the duration of a blast with the interval between repeated blasts. • Eliminate any choices that match the typical length of a prolonged blast or a danger signal (5 or more short, rapid blasts), since those would be too long for a single short blast.
