VESSEL TRAFFIC SERVICE For procedures and working details of the Terschelling (Brandaris) Vessel Traffic Service, see The Netherlands Coast Pilot (HP 1). CENTRAL REPORTING POINT WADDENZEE For all reports and information. Telephone: +31 (0)88 79 74 599 VHF 4 (Safety and distress calls : VHF 16) DEPTHS AND BUOYAGE The channels and depths shown on this chart are subject to frequent change; the buoyage is adjusted accordingly. For the latest information mariners are advised to consult Brandaris Vessel Traffic Centre, VHF 2. 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. WINTER-BUOYAGE From ± October-April buoyage may be replaced by winter-buoyage. In severe winters buoyage is withdrawn. Buoyage will be replaced in order of importance. In spring it is possible that not all channels are already buoyed as charted. 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 by up to 2 metres. They may also span seabed undulations and cause fishing gear to become irrecoverably snagged, putting a vessel in severe danger. See the Netherlands Coast Pilot (HP 1).
