Hi Stevie
Skegness is my home town, cut my teeth fishing marks all along this coast, first thing to tell you is depends what you call 'deep' marks, mostly shallow sandy beaches very few features, as already said look for the gullies, usually being able to chuck a lead a decent distance will improve chances greatly, Skegness beach itself can throw up a few fish but really need to be heading north along coast road, lots of marks all easy to access. Ingoldmells point can produce fish in the right conditions, heading bit further north towards chapel st leonards, trunch lane, chapel point, six marshes, moggs eye, wolla bank and huttoft will all produce in the right conditions, usually all high water marks but north of chapel can fish well over low water even though most people don't bother, sad to say doesn't fish as well as it used to and word from mates in the area is loads of whitey's very few cod!!
Hope this helps!
Dave
