Anchoring prohibited
Areas & limits
An anchor struck through (printed magenta) forbids anchoring — usually protecting cables or pipelines.
What it means
An anchor symbol with a bar struck through it, printed in magenta, marks an area where anchoring is prohibited.
Why it matters
These areas usually protect submarine cables, pipelines, or fairways. Anchoring there risks your gear, the infrastructure, and a hefty fine — check what the zone protects before even a 'quick stop'.
