In this work, a modified non-linear theory for modelling the propagation of steep waves is presented. The new approach is fast and precise and applicable in day-to-day use for experimental investigations. It is capable of upstream transformation of wave trains and therefore ideally suited for generating wave board control signals. The potential of the reproducible procedure is demonstrated by generating different kinds of tailored deterministic wave sequences such as transient wave packets, sea states with deterministically embedded steep wave trains, regular waves with a superimposed Three Sisters wave, and observed wave records (“New Year Wave”). As an exact and reproducible encounter of ship and wave in the model basin is realized by a deterministic test procedure, these wave scenarios can be analyzed from the point of view of a sailing ship, and mechanisms of large rolling and capsizing can be examined deterministically. Different extreme and resonance phenomena — such as parametric roll and loss of stability at the wave crest — can be investigated. Based on these developments, methodologies for the quantitative assessment of capsizing risk are validated by direct comparison of time series from numerical and experimental simulations — providing a basis for the improvement of current intact stability criteria.
