Ha ha, no I think its just that they don't bother in the winter, most of the time there's no one moored there anyway. as I say, I've never been approached for mooring fees anywhere in winter, another plus for going out of season!
I agree, the Chet is not a problem for me, I wish I had a quid for every time I've been down there. I pretty much know every twist and turn by now. But I think Simon's point is it could be a little daunting for folks with limited experience or who have never been before.
