Background: high speed crafts experience a harsh vibration environment, and hence human response to this environment is of increasing interest to ship architecture engineers who wish to reduce the effects of vibration and shock. Aim: In this research, an attempt is made to place an anti-vibration plate on the floor of the high speed craft’s cabin with the help of installing elastomeric bases on the bottom of the plate. To prevent blows caused by waves to the body of the vessel's personnel, as well as possible damage to the navigation equipment in the vessel. Methodology: In this research, with the help of viscoelastic modeling and the use of passive isolators, an attempt is made to reduce the vibrations and shocks caused by turbulent sea waves in the floor of the high speed craft’s cabin. Assumptions: In this research, it is assumed that the floor of the high speed craft’s cabin is a separate plate and all the equipment including the main dashboard, seats and navigation aids are placed on this plate. Findings: reducing the vibrations in the cabin of the high speed craft under shock loading; Using an anti-vibration plate. Conclusions: Finally, the results of coding and the diagram of different states are compared with each other to determine the optimal state.
