That leaflet was my first source of information about the area, I have found it pretty useful.Never fished there but quote from "fishing around Maldon" leaflet by Bob Cox ....."Thornback Rays-worth considering from the beach from Stone to Stansgate where a relatively short cast of 50-80yds with squid, fresh herring or peeler will produce 2.5 hrs each side of LOW water----Bass -Stone to Stansgate over same LOW water period can be productive especially if
coinciding with dawn or dusk. Crab or rag favourite or lures if water is clear"
Hope this of some help.. Anyway I reckon thats one of the most beautiful bits of Essex Best of Luck
