Hollow Boats

You can use the below techniques to create a hollow area inside of a boat, which will prevent the water plane from dawing within the area. This is done by creating an inner hull that is a duplicate of your outer hull but uses a special shader.

Specific to Hydro, one possible workflow would be to use your inner hull as the primary child of your HydroRigidBody. Since it only serves as a visual mask to keep water out, you can simplify its geometry relative to the outer hull which will have more visual detail. The simplified geometry will help performance of the physics calculations, compared to using a higher-poly outer hull as your primary child.
