Air Ships

There are often ships sheltering at the eastern end of Lyme Bay, sometimes due to forecast westerly storms, sometimes, like now, due to the economic climate (waiting for a buyer for gas or oil or whatever). They provide an income for the local harbours for servicing, ferrying to hospital, shops etc
These are waiting, tethered by gossamer anchor chains, floating on a zephyr.
