Just off the coast of Catalina, there’s a vessel that doesn’t sail above the waves—it slips beneath them. Inspired by a legendary submarine, the Nautilus offers a front-row seat to an underwater world few have witnessed. And what happens when you push the torpedo button? Well… that’s something you’ll have to see for yourself.
