Question 1 of 27070

BOTH INTERNATIONAL & INLAND Which is the duration of each prolonged blast on whistle signals used by a power-driven vessel in fog, whether making way or underway but not making way?

🔍 Key Concepts

• Rule 35 – Sound signals in restricted visibility (Navigation Rules) • Definition of a prolonged blast vs a short blast • Standard fog signal pattern for a power-driven vessel underway (making way and not making way)

💭 Think About

• First recall the standard time range given in the Rules for a prolonged blast and for a short blast—how many seconds does each last? • Which of the answer choices best matches the official time range for a prolonged blast, not a short blast or a series of blasts? • Eliminate options that are clearly too short to be ‘prolonged’ and too long to be practical for repeated fog signals every 1–2 minutes.

✅ Before You Answer

• Look up the exact wording in Rule 32 – Definitions and Rule 35 – Restricted visibility in the Navigation Rules. • Confirm the specified time duration range given for a prolonged blast (expressed in seconds). • Make sure you’re not confusing the length of a blast with the interval between signals (which is given in minutes).
