Head? It goes over shoulders (4)
I believe the answer is:
cape
I believe this is a double definition.
'head?' is the first definition.
(both can mean a piece of land jutting over the sea)
'it goes over shoulders' is the second definition.
(a cape is worn around one's shoulders)
(Other definitions for cape that I've seen before include "Batman has one" , "Wrap" , "Cod, for example" , "Point of land jutting out into the water" , "Head; garment" .)
