The Houdini Master Class on the new ocean tools has a setup for this on the downloads on Side Effects site that go with the instructional videos.

It includes chops for creating lag and it's easy to add other controls to limit the specta's influence on the floating object.

It uses a three point system that you can move outwards or inwards towards the floating object giving the effect of dampening or widening the effect of the waves on pitch and roll.

Also by translating this three point system you can get your boat for example to move through the ocean after you pack it and copy it to points.

Works quite well actually and is simple.
