By introducing model of ship kinetic, the visual simulation system on operation of break bars boat was designed and realized. The experiments of its combat for varied conditions were carried by using the simulation system. Ocean LOD dynamic meshes for different wave spectrums were created and optimized. Particle system was used to implement the special effects, such as bow waves, stern wake, and water column. An index system for synthetic evaluation of the operation efficiency was set up. The fuzzy synthetic evaluating model and method were given, and the practical examples of the simulation were evaluated based on the method Evaluation results demonstrate that the simulation system is creditable.
