A swinging couch or bed, usually made of netting or canvas about six feet long and three feet wide, suspended by clews or cords at the ends. [ 1913 Webster ]

2. A piece of land thickly wooded, and usually covered with bushes and vines. Used also adjectively; as, hammock land. [ Southern U. S. ] Bartlett. [ 1913 Webster ]

Hammock nettings (Naut.), formerly, nets for stowing hammocks; now, more often, wooden boxes or a trough on the rail, used for that purpose.
