The Real Time Ship Simulator is an addon that calculates the physics of floating objects interacting with simulated water. It uses a physically based solver to process ship dynamics in real time, factoring in the geometry of the target object through a calculated guide mesh. Users can adjust parameters such as floatability, buoyancy, and initial velocity to achieve realistic movement.

The tool integrates natively with Blender's Ocean modifier as well as custom ocean meshes. Simulations can be setup via a dedicated sidebar panel, initialized at a specific frame, and baked into standard keyframes for final rendering or export to other applications.
