Paper

The main component of high-speed craft (HSC) roll damping is due to the hydrodynamic pressure developed on the hull surface: this is very different from the case of displacement hulls. However, the estimation of roll damping of HSC, by means of roll decay tests for example, is often treated in the same manner as for larger and slower ships. Being able to model correctly the roll motions of...

Paper

The prediction of planing hull motions and accelerations in a seaway is of paramount importance to the design of high-speed craft to ensure comfort and, in extreme cases, the survivability of passengers and crew. The traditional approaches to predicting the motions and accelerations of a displacement vessel generally are not applicable, because the non-linear effects are more significant on...
