DEPTHS AND AIDS TO NAVIGATION Depths are subject to frequent change. Actual depths may differ from the charted soundings and depth contours. The buoyage and aids to navigation will be adjusted accordingly as well as possible. DREDGED DEPTHS The depths shown for the dredged areas are generally maintained but are frequently liable to siltation and shallow depths can occur. Therefore it is advised to contact the port authorities about this. VESSEL REPORTING For details of the Westerschelde Vessel Traffic Services Scheldemond (VTS SM) including Traffic Area Gent-Terneuzen, see the Netherlands Coast Pilot (HP1) or ADMIRALTY List of Radio Signals. WESTERSCHELDE SHIPPING REGULATIONS (WSR) In the Westerschelde and approaches, traffic regulations ''The Westerschelde Shipping Regulations 1990'' are in force. For details see the Netherlands Coast Pilot (HP1) or ADMIRALTY Sailing Directions. 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. ''FIETSPAD'' SMALL CRAFT CHANNEL Small crafts are urgently requested to use the channel parallel to the main fairway, named ''Fietspad'' and marked with yellow buoys. Ask the local VTS for the least sounded depth. VESSEL TRAFFIC SERVICES SCHELDEMOND Ch 11 Terneuzen Port Control (See Netherlands Coast Pilot HP1) SOUNDING DATUM CANAL GENT TERNEUZEN Depths in metres.
