That's really weird.
When I looked earlier, there was a big fat grey striped area from the NW coast out to the shore-most edge of the red marked wind farms. It ran all the way from Morecambe Bay down past Fleetwood (the straight line you can see going through Morecambe Bay was one edge of it) and along the coast.
Maybe I was hallucinating - but if there is no exclusion zone, why have it on the key to the map? It's gone off the other maps too - maybe it's something to do with the PC at work I was using. Oh well.
Or, it could just be the power of RIBnet............
