VESSEL REPORTING For details of the Nieuwe Waterweg Vessel Traffic Service see the Netherlands Coast Pilot (HP1) or Admiralty List of Radio Signals. FAIRWAY NIEUWE WATERWEG The fairway Nieuwe Waterweg is limited as indicated due to permanent obstructions, see the Netherlands Coast Pilot (HP1) or Admiralty Sailing Directions. PRECAUTIONARY AREA The port entrance at Maasgeul is part of the MAAS CENTRE precautionary area. Passing traffic that is not entering or leaving the adjacent ports should avoid the precautionary area. Anchoring in the precautionary area is not recommended. DEPTHS AND AIDS TO NAVIGATION The channel depths are liable to frequent change and the buoys are moved accordingly. Charted details cannot always be relied upon. DEPTHS IN HARBOURS Depths in harbours and along quays are maintained by dredging. For the latest information consult the pilot. SUBMARINE CABLES AND PIPELINES Mariners are advised not to anchor or trawl in the vicinity of submarine cables and pipelines. Pipelines are not always buried and their presence may significantly reduce the charted depth. They may also span seabed undulations and cause fishing gear to become irrecoverably snagged, putting a vessel in severe danger. NATURE RESERVES Entry into the nature reserves shown on this chart is defined by numerous restrictions and prohibitions. For further details see www.rwsnatura2000.nl. PORT SIGNPOSTING SYSTEM Berth numbers e.g. 6001-6105 relate to the Port Signposting system. These numbers correspond to the numbering of the waterfront. The port numbers are indicated in black figures on yellow boards. TIDAL STREAMS Attention is drawn to the strong tidal streams in these waters. For tidal streams and tidal information see: HP 33 Tidal heights and streams for coastal waters of the Netherlands and adjacent waters and HP 33D-NLTides published by the Netherlands Hydrographer.
