I don't have the cartographic internal picture of the Lakeland Fells that Lytham has, though I wish I did, as I've been up them all. I can say, looking at the map, that if the Big One appears to the west of the Tower, then the viewing point must be deep into the Ribble Estuary, around Hesketh Bank / Tarleton, in which case you'd be looking straight out onto the Irish Sea, not at the Lakes, I reckon.
Very happy to be proven wrong, though, as the views of the Lakes from Fleetwood can be particularly stunning, and perspective plays strange tricks.
