A guide to navigating Maplin and Foulness Sands

Range Sea Danger Area

The Maplin and Foulness Sands area surrounding MOD Shoeburyness is very popular for recreational sailing, watersports and fishing. If you intend to sail, board or paddle nearby you should be aware that the area outlined on the map below is a Range Sea Danger Area.

The Range operates Monday to Friday (and occasionally on weekends), all year round and is shown as being ACTIVE by the flying of Red Flags. If you are unfamiliar with navigating in the area or if you believe you have a legitimate reason to request entry to the the Range Sea Danger Area, you must contact MOD Shoeburyness as follows:

  • Range Control: 01702 383211
  • Marine Control: 01702 383311
  • Marine VHF: Channel 72 & 16 (Call sign "Shoe Radar")

The area falls within the jurisdiction of the Shoeburyness Artillery Ranges Byelaws 1936 and the Shoeburyness and District Military Lands Byelaws 1935 (under the Military Lands Acts 1892 to 1903) which govern the rights of passage through the Inner and Outer Sea Areas that make up the Range Sea Danger Area. The byelaws exist and are applied in the interest of public safety and ensure that the Range can operate without presenting a risk.

UNAUTHORISED ENTRY INTO THE SEA DANGER AREA BY ANY TYPE OF VESSEL IS PROHIBITED AND DANGEROUS.
