## Using the Dynamic Ocean to Drive a vessel

He Guys,

Looking at the Imposter object I figured that this can be used to drive the motions of a Vessel floating in an ocean.

However, I could not figure out how to connect it to a part so I guess my English is limited... :(

In short:  Is a dynamic ocean indeed capable of driving the motions of a part floating in it?

And if so:

- How?

- Is that then based on force coupling or is it based on a motion coupling?

Kind regards,

Chris

Hi Chris,

The Imposter is an extension that clips the water graphics so you don't end up with water in the hold of your ship:

To make a part float in the Ocean object (or a Fluid Surface), you need to set a few parameters at the Part level:

If all you want is to follow the surface motions of the waves, and not collide with anything, you could use a Buoy extension:

But in your use case I would model the hull of the ship with a part and buoyancy, to get the proper hydrodynamics (roll, etc.).

Hi Chris,

Forget using the Buoy option -- I just tried it (took 30 seconds), it doesn't work well.

To get a proper interaction with the Ocean, you'll need to add a hull. If you don't have one (or if the shape is not important), you could always use the Norman Kraken ship found in the Vortex Samples...
