Which chart symbol indicates an underwater cable that prohibits anchoring?

• A. Cable area symbol
• B. Tide station symbol
• C. Wreck symbol
• D. Current arrows on chart

Answer: (A)

Anchoring near submerged cables can damage the cable and create hazards, so charts identify these routes with a cable area symbol to warn mariners that anchoring is not allowed there. This symbol specifically marks the presence of an undersea cable and the associated prohibition on anchoring, helping you avoid costly damage and safety risks. Other symbols point to tide gauges, wrecks, or show current direction and strength, but they don’t indicate cable presence or anchoring restrictions. So the cable area symbol is the one that conveys both the existence of the cable and the no-anchoring rule.
