No more Hollywood movies for you. The only "tsunamis" with "waves" hundreds of feet high are created by cliffs or glaciers collapsing. And even then, the wave height is really the run-up against another cliff or mountain. Such waves can be dangerous to boats in confined waters, such as a bay. In the open ocean, tsunami waves are mostly harmless and even barely noticeable to boats. And all this is moot because the slip-strike motion of the San Andreas fault doesn't produce tsunamis that I've heard of.
