Animation Software

I have modeled a few boats in 3DMAX7 and want to create animations for showing clients. I am looking for a MAX plugin that will animate ripples and waves as the boat sails thru water in a fairly realistic but not necessarly accurate manner. I am looking at these two PLUGINS...

DREAMSCAPE

and

SEASCAPE

Any suggestions.

Thanks

 

Here is another good plug in for 3D studio
