Q

BOTH INTERNATIONAL & INLAND Signals required for vessels aground include __________.

🔍 Key Concepts

• Vessel aground vs. at anchor – what extra signals are required when a vessel is aground compared to just being at anchor? • Sound signals in restricted visibility for vessels aground (Navigation Rules – Part D, Sound and Light Signals). • Day shapes and lights – what does three balls by day and three red lights by night indicate?

💭 Think About

• First decide: what shape or light indicates a vessel is aground, and how is that different from a vessel simply at anchor? • Next, think about whether vessels aground have any special sound signals in or near areas of restricted visibility. • Finally, ask yourself: does the rule for vessels aground combine both day shapes, night lights, and sound signals, or only some of these?

✅ Before You Answer

• Verify in the Navigation Rules that three black balls in a vertical line is the day shape for a vessel aground. • Check what additional lights at night are shown by a vessel aground beyond ordinary anchor lights. • Confirm in the sound signal rules whether a vessel aground in restricted visibility must sound a pattern of short and prolonged blasts, and exactly which pattern is described.
