Abstract
Ice ingestion by the Polar Class Icebreaker propellers has resulted in significant failures and resultant downtime. In 1978 the Coast Guard began an evaluation of potential ice deflecting hull appendages. This program included construction of, and laboratory experiments with, a twenty foot self-propelled model. The results of these efforts and identifiable future research efforts are described.
