I. The third class of rating on Lloyd's books, for the comparative
excellence of merchant ships. (_See_ A.)
ICE-ANCHOR. A bar of round iron tapered to a point, and bent as a
pot-hook; a hole is cut in the ice, the point entered, and the hawser
bent to the shorter hook; by this vessels ride safely till any motion of
the ice capsizes it, and then it is hauled in. The ice is usually
entered by a lance, which cuts its hole easily.
