Abstract: This paper describes the second phase in the development of a river ice-prow intended to be attached to a towboat for opening navigation channels or for ice management in the vicinity of the locks and dams on the northern rivers of the United States (Illinois, Ohio, and Upper Mississippi Rivers). The first prow concept, presented at the 1986 IAHR Ice Symposium in Iowa City, proved during model tests to be less maneuverable than desired. Most of the difficulties were attributed to the side ice-cutters and to a poor lengthwise weight distribution. The bow was redesigned and the side cutters were eliminated. Model tests showed greatly improved maneuverability in ice without significant effect on the icebreaking capability of the prow. The results of these tests are presented and discussed.
