Hi macaddict! I'm assuming you read litst's ideas for a wake on water in the ealier post (30 October 2001). You can animate that wake by changing the coordinates of the rectangular layer in the bump channel. It's very tricky to get right. Another way is to make a wake object, small plane or rectangular prism with the wake waves either as geometry (again difficult to model) or as a bump map as per litst's ideas. This object should have the same water shader as your ocean. Moving the wake object gives you the animation From your comment I take it you are talking of an aircraft or ship flying close to the water. Have a look at the picture of the low flying B1 bomber at the link. Looks like you'll need to animate som particle systems as well. Have fun.
