You can easily see Drax power station on a clear day from the hills above Sheffield so I suppose with a very good pair of binoculars you could see the Humber, which is tidal. I think the 'horizon' calculation precludes seeing the 'proper' sea near Cleethorpes or Spurn Point, and anyway the Yorkshire/Lincolnshire Wolds would block it, unless the relatively small gap caused by the Humber could allow it.
From my school just west of Doncaster, 100m above sea level, you can just see the top of the Humber Bridge by eye on a clear day if you know exactly where to look for it, so that might back up the impossibility.
I'm sure I read somewhere that it is impossible to see the North and Irish Sea from the same point, though you would think somewhere like Cross Fell in Cumbria would have a chance. I wonder what would happen if you could climb to the top of Holme Moss TV mast on the moors above Holmfirth?
Looking at the online panoramas, it would appear you cannot see both the North Sea and the Irish Sea from a single location anywhere in England or Scotland.
The closest I've found is from the top of Ben Nevis, where it's possible to see the Atlantic and a glimmer of North Sea (just near Inverness - see link).
