Part of the prestigious Nautilus Fleet, this former research vessel offers seasonal itineraries in two of Mexico's most dynamic diving destinations - Socorro and Revillagigedo, and Guadalupe. This spacious and modern motor yacht was refitted for liveaboard diving in some of the Pacific's most remote waters, delivering once in a lifetime underwater experiences paired with exceptional guest service. Dive up to four times a day, snorkel with marine wildlife during surface intervals, kayak and paddleboard, and indulge in a few onboard creature comforts when you aren't too busy adventuring!

The Nautilus UnderSea proudly caters to a wide variety of guests with its diverse itineraries and intuitive service. Their team is happy to look after intermediate explorers closely, and give a bit of extra freedom to independent and advanced dive buddies - the choice is yours. And, the Nautilus Fleet's signature "dive butler" service helps each guest decide how much, or how little, assistance they want, ensuring that divers of all skill levels have the time of their life. Choose from trips to Mexico's most remote diving regions known for cool water, powerful open ocean currents, and potentially challenging surface conditions. Or, hop into some of the Pacific's most shark-filled waters for a chance to observe great whites.
