BOTH INTERNATIONAL & INLAND You are underway in fog and you hear one prolonged blast followed by two short blasts. This signal indicates which vessel?

🔍 Key Concepts

• Rule 35 – Sound signals in restricted visibility • Difference between underway but making way and underway but stopped • Which vessels have distinctive fog signals (e.g., towing, fishing, NUC, RAM, pilot)

💭 Think About

• Ask yourself: which sound pattern (one prolonged + two short) is specifically assigned to certain types of vessels in fog rather than just their status of motion? • Consider: does this signal describe what the vessel is doing (e.g., towing, aground) or its special operational status (e.g., restricted in ability to maneuver, pilotage duty)? • Think: in fog, which vessels need to clearly identify themselves because of their special operations, not just because they’re underway?

✅ Before You Answer

• Look up the exact wording under Rule 35(c–j) to see which vessel uses one prolonged followed by two short blasts at intervals not more than 2 minutes. • Verify which option describes a vessel that the Rules classify as a vessel engaged in special operations rather than just a normal power-driven vessel. • Confirm that you are not confusing the underway making way/stopped signals (one or two prolonged blasts) with the signal that adds two short blasts.
