Q

BOTH INTERNATIONAL & INLAND While underway in fog, you hear a short blast, a prolonged blast, and a short blast of a whistle. This signal indicates which vessel(s)?

🔍 Key Concepts

• Sound signals in restricted visibility per COLREGS/Navigation Rules Rule 35 • Different patterns for power-driven underway, towing, anchored, and sailing vessels in fog • Meaning of prolonged blast vs short blast in fog signals (not maneuvering signals)

💭 Think About

• Recall which vessel types use ONLY prolonged blasts at fixed intervals when underway in fog, and which add short blasts to that pattern • Think about whether anchored vessels in fog use only bell/gong, or bell plus whistle, and what the timing and pattern are • For towing situations in fog, consider how the towing vessel’s signal differs from the signal of the vessel(s) being towed

✅ Before You Answer

• Match the exact sequence (short–prolonged–short) with the pattern given in Rule 35, not maneuvering rules like crossing/overtaking • Confirm whether the signal described is for a vessel making way, underway but not making way, anchored, or towing • Verify which vessel types in restricted visibility signals specifically use one prolonged and two short blasts and whether that order matters
