This paper describes the background, inception, objectives and current status of the Transport Canada ACV Icebreaking Bow Development Program, which involves three phases of activity, each having an appropriate level of model testing, theoretical development, economic analysis and full-scale testing. The three-year program of research which commenced in 1975, under sponsorship by Transport Canada Research & Development Centre, is still continuing, in fact, it is currently about halfway through. So promising are the Phase I test results, details of which are offered in the following pages, that already the Canadian Coast Guard is undertaking the design development of a prototype "Air Cushion Platform Icebreaking Attachment" and has plans for its actual construction and early deployment in the icebreaking fleet for service in the rivers and lakes of Canada. At the same time, the challenge has been accepted by commercial interests to explore this new icebreaking principal in relation to their emerging winter navigation needs, and to assess its impact on such concepts as year-round operation of ships on the Great Lakes.
