Yes, it is. I considered "parking" the ships (furled sails), but I like the billow. Frankly, I find the lack of crew on-deck and in the rigging for more odd than the smooth sea and full sails!
I keep considering "postwork", but I figure that I'd have to put the stuff in "photo-manipulation" or somewhere else other than 3D to be honest... and to be honest here, Bryce will provide the lighting and shadow effects, but at a cost in render time (esp. on a 1.6ghz, 1.5gb gateway laptop ) that makes "prohitive" a true understatement.
I tend to go for false beauty over real photorealistic way too often
