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 ± December-March 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 In severe winters buoyage is withdrawn.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. SUPPLEMENTARY MARKS In these waters supplementary marks for pleasure craft and special marks for areas meant for waterskiing, kite surfing, jet-skiing and fast motorboats and areas under the Nature Conservation Act are on station from ± April-October. 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. Outside the fairways the cables and pipelines are marked by steel pipes with an elevation of 4 dm above the sea floor. See the Netherlands Coast Pilot (HP 1) for more information. POLLENDAM FAIRWAY Pleasure craft are urgently requested to use the channel parallel to the 'Vaargeul langs Pollendam'. The yellow floating beacons mark at least the 1.8m depth contour. If you can not use the recommended recreation track along the yellow buoys of the Pollendam, it is essential to keep 30 metres clear of the dam. Mind the cross current which occurs when the dam is flooded; depending on the current direction it may set you towards the dam. BLAUWE SLENK AND VLIESTROOM RECOMMENDED TRACKS The recommended track for pleasure craft along the Blauwe Slenk and Vliestroom is marked with yellow buoys. Ask Meldpost Waddenzee (VHF 4) for information on the least sounded depth. VEERBOOTROUTE AMELAND The fairway of the Veerbootroute Ameland between buoy VA 11 and the Holwerd ferry jetty is liable to frequent changes. Buoyage is adjusted frequently. Mariners are advised to navigate with caution and follow the marked fairway.
