Q

BOTH INTERNATIONAL & INLAND While underway in fog, you hear the rapid ringing of a bell for about five seconds followed by the sounding of a gong for about five seconds. This signal came from which vessel?

🔍 Key Concepts

• Sound signals in restricted visibility from COLREGS/Navigation Rules Rule 35 • Bell and gong signals for vessels at anchor and aground • Length threshold (in meters) that changes the required anchor sound signal pattern

💭 Think About

• Ask yourself: which type of vessel uses both a bell and a gong in fog, and under what length or status condition? • Compare the required signals for a vessel at anchor, aground, and underway but not making way—which one matches rapid ringing of a bell followed by a gong? • Think about whether vessels under 100 meters and vessels 100 meters or more at anchor make the same or different sound signals.

✅ Before You Answer

• Verify in Rule 35 what sound signal is required for a vessel at anchor 100 meters or more in length. • Check how the sound signal for a vessel aground differs from that for a vessel simply at anchor (what extra sounds are added?). • Confirm whether a sailing vessel or fishing vessel at anchor has a different fog sound from any other power-driven vessel at anchor.
