Weather routing methods find the most suitable ocean’s route for a vessel, taking into account changeable weather conditions and navigational constraints. In the multicriteria approach based on the evolu-tionary SPEA algorithm one is able to consider a few constrained criteria simultaneously. The approach ap-plied for a ship with hybrid propulsions has already been presented by one of the authors on previous Trans-Nav’2009. This time a motor-driven version of the solution is presented. The paper is focused especially on a proposal of ship safety measure, based on restricting the impact of weather hazards on the ship. Besides the weather conditions and navigational restraint the safety of a vessel is one of more important factors to be con-sidered. The new approach towards a safety factor modeling is described and implemented.
