The operation of a variety of ship types involved in Seaway and overseas trade is examined. These include Great Lakes and oceangoing bulk carriers, dry cargo ships, container ships and alternative container feeder vessels. Details of mathematical models are given for each ship type, and a set of designs is evolved for operation on different trade routes. A series of parametric studies illustrates the senstivity of the ship's economic performance to changes in the operational characteristics. Specific attention is given to the effects of changes in delay assumptions, cost levels, ship sizes and lock sizes. The results show the relative significance of the different variables in the transportation system. Alternative container feeder vessels for the Great Lakes/St. Lawrence system are presented and an apparently viable feeder vessel is proposed. Comparison is then made with competing rail services. Finally a summary of the results is presented.
