Ocean, You need to render the boats twice and then composite together in video post. First render the complete scene and the water can be showing through the hull. Next render just the boats with no ocean against a black background and with alpha channel on. If there are any objects inside the boat you can render them too, or if you rendered them in the first pass then you'll need to make them matte objects (modify/object/ attributes). Then composite the 2 scenes together in video post: the first layer is the complete scene, the second layer is the boats (and possibly occupants) with alpha = queue alpha channel.
