In the ever changing usage of the English language the term 'Anorak' has come to mean not only a garment of clothing but also a (slightly derogatory) name for anyone fanatically interested in the minutiae of any subject - from railways to motorcycles or even television programmes. It is a term also generally applied to the offshore radio enthusiast or 'free radio fan' as they were once called.
The origin of this can be traced to a visit by free radio fans to the radio ships off the Dutch coast in the early summer of 1973. As such a boat trip circled the Mi Amigo two of the Radio Caroline DJs, Andy Archer and Graham Kaye, were presenting a live report from on deck.
During the report Andy Archer referred to the number of fans wearing anoraks on that hot summer day and thanked "all the anoraks" for coming out to visit the radio ship. The term has since come into common usage when referring to anyone interested in offshore radio and has spread to embrace others with specialist minority interests.
HOLD Noun - cavity in a ship below deck where cargo is stowed. Also the area used to house transmitters on many radio ships.
