PRECAUTIONARY AREAS
Vessels entering the NORTH HINDER JUNCTION, MAAS JUNCTION, MAAS CENTRE, 
SCHOUWENBANK JUNCTION and the vicinity of THORNTON and BLIGH BANKS precautionary 
areas should navigate with extreme caution as vessels on route to and from TSS off Texel, 
IJmuiden, the Westerschelde and Europoort may be merging or crossing.

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.

for certain tankers and other vessels, see the Netherlands Coast Pilot (HP1) or Admiralty Sailing Directions.
