Analysis of inherent course stability of a high-speed catamaran in deep and shallow water

摘要

The paper treats the important problem of prediction of ship's inherent course stability, based on a large amount of model experimental data for a well-known bare hull shape - the Delft catamaran 372, covering a comparatively wide range of Froude numbers and depth to draught ratios. The analysis is based on a linearized maneuvering model. As a result, dependency of the stability criterion on Froude number and the water depth to draught ratio is established and clearly demonstrated for this particular ship case.
