Channels to Mand
The seabed around Mand is subject to constant changes due to sand migration. 
There are two buoyed channels which lead to Mand S, one from Gydelbet in W and one from sterdyb in E. 
The buoyage of the two channels is established 1.5.-15.11. Only the channel from sterdyb is shown in the chart. 
It is not recommended to use either of the buoyed channels without local knowledge.
