CABLES AND PIPELINES
Mariners are advised not to anchor or trawl in the vicinity of
cables and pipelines. Pipelines are not always buried and their presence may
effectively reduce the charted depth. 
They may also span seabed undulations and cause fishing gear to become
irrecoverably snagged, putting a vessel in severe danger. 

DEPTHS AND AIDS TO NAVIGATION
The channels and depths are subject to frequent change. The buoyage and other aids to navigation are adjusted accordingly. 
For the latest information see Notices to Mariners or consult the pilotage authorities.

MAINTAINED DEPTHS
The maintained depths charted are reduced to Chart Datum. They are intended to be maintained. It must be taken into account that they are not always present everywhere.
