Description/Abstract

The partial air cushion supported catamaran concept (PACSCAT) can offer an efficient solution when a
relatively high payload is required to be carried at relatively high speeds with a restricted draught. Such
circumstances reflect potential modes of shallow water operation in inland waterways such as the Rhine and
Danube.
In support of the development of the concept, numerical models of the resistance and wave wash
characteristics have been developed and extensive tank tests in shallow water carried out. A theoretical model of
the cushion has been combined with thin ship theory representing the side hulls. The developed model offers the
facility to make performance estimates of the powering and wave wash for various operational scenarios.
The paper also describes the choice of propulsor for the vessel, from the options of open propellers, ducted
propellers or waterjets. It is found that the best propulsive efficiency can be achieved with the use of ducted
propellers.
