No mate you are thinking of Mucky Bay. The Boating Bay is just north of Easington. There is a right turn (heading north) just before the old dog track IIRC, you follow that for a mile or so until it comes to an end, then there is a footpath that crosses the train tracks and leads down to the beach. It is a smallish bay with rocky skeers to the north and south, fairly deep water I think but as I say only fished it the once years ago.
Mucky Bay is an excellent mark, or at least it used to be back in the day.
