Ship Simulator is introduced as a new physics simulation model because there is no library module supporting this in 3D programming platforms. For example, Unity and SceneKit have road vehicle models with Engine and Steer methods, but they do not simulate floating structures on the surface of liquids.

Here is a video recording the simulation process of a large truck with 10 wheels. We pay attention to the vehicle’s suspension system, it represents spring forces very well

A ship simulation system at sea includes simulation of ocean waves with different wave levels, simulation of the ship with hydrodynamic buoyancy, wave and wind forces in which shallow water is considered, water resistance along with ship characteristics affecting ship speed and determining the ship’s turning radius, thrust, propeller pitch and steering system

Challenge for you:

The ship is sailing in rough sea. A large wave hits the ship’s side, causing it to nearly stop. The action forces act at the wetted areas of the hull. The total force acts at the center of gravity of the wetted hull. Think about how to find this center of gravity.
