Nautilus Liveaboards

"Swim with the friendliest giant mantas in the world at Socorro Island, or go face to face at 30 ft with great white sharks of Guadalupe Island. Big Animals, Big Adventures. With over 25 years experience, we have a pretty good idea of when and how to get you in the water for the best possible diving experiences off Baja California (Mexico). The Nautilus Explorer is 1 of 3 luxury live aboard boats owned and operated by Nautilus Liveaboards. The Explorer and her sister-ships Belle Amie and Under Sea specialize in multi-day great white shark expeditions as well as giant manta and humpback whale trips." (from the business)
