Fished at Huttoft quite a few times in winter for cod, etc, and for smooth hounds in the summer, best time of day is the 1st 2 hours of the flood tide in the evening as the fish come closer in to feed, look at the beach when the tide is out and you will see gulleys in the sand, this is where you want to be casting to. (appx 30->50yds)
For flatfish, eels, and the occasional bass the best bait is lugworm with a tippet of mackeral, for smoothhounds you will need strong gear, these are basically small sharks and go off like the proverbial rocket if you hook one, best bait for these is peele
