In the movie the sailor sheets out in the gust and that makes the nose rise. He then also leans the whole rig backwards and the sail is then pulling everything upwards rather than forward. A similar technique can be used to purposely pop a board out of the water and jump on flat water. A smaller fin would not have help here, he is simply overpowered.
