Video: The Dawn Treader Rocks

NarniaWeb Spy Tamara has uploaded two more videos of the Dawn Treader set at Cleveland Point. The first one shows the ship slowly rocking back and forth in front of a large blue screen:

Another shows Ben Barnes and Skandar Keynes being sprayed with water, which Tamara also described in a recent report. Is Caspian wet after diving in to save Lucy, Edmund, and Eustace?

UPDATE: This video shows the actors performing as the ship rocks:

UPDATE: In this video, Caspian appears to be taking Edmund into the cabin.
