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.

SPEED RESTRICTIONS
In these waters restrictions for sailing with fast
motorboats and waterskiing are in force.

CABLES AND PIPELINES
It is prohibited to anchor and 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.

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In severe winters buoyage is withdrawn.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.

CHANGING FAIRWAYS
Due to strong currents the fairways are changing continuously.
Actual depth may differ from the charted soundings. The buoyage
is adjusted accordingly.

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.

MARINE FARM
In this area Marine farms may occur. These devices are marked 
with yellow buoys with entry prohibited signs.
