The authors would like to thank the Spanish MCYT, “Ministerio de Ciencia y Tecnología”, for their support (project DPI2000-0386-C03-02), the CEHIPAR staff for their cooperation, and IZAR for its recommendations.The vertical motions of fast ships, which have a negative effect on comfort and safety, can be attenuated using moving actuators. There is the need of a control strategy to move the actuators in the most convenient way, considering several objectives. The paper considers this problem, studying a practical real example. Experiments with a scaled down replica of a fast ferry has been done, first for modeling purposes and second for control studies. Linear control shows serious application problems. Taking this into consideration, a nonlinear control approach is devised, with satisfactory results.engbook parthttp://www.dacya.ucm.es/giron/PDF/josemaria.pdfhttp://www.dacya.ucm.es/open access004Ship ControlMarine SystemsNonlinear ControlMultiobjective OptimizationInformática (Informática)1203.17 Informática
