As sharks, whales, tunas and marlins populations plummet, we must carefully choose sustainable actions if we ever hope to keep these big pelagic species from extinction. Through ecotourism, a world where pelagic species thrive and flourish is possible. We know, because we witnessed it, and it was magical.
Our Values – Our Culture
Built for Safety
Most divers would be shocked if they knew what was going on in the engine room and below decks of many liveaboard diving ships. Safety is not something to ever take lightly. We live and breathe safety with obsessive compliance to our Safety Management System under the watchful eyes of our external auditors. See our passenger and safety certificates here.
Excellence in Guest Experience
Captain Mike has led the way for the last twenty-seven years in consistent and relentless obsessive attention to detail, and making every trip as excellent as possible. That attention to detail shows up everywhere, from each dive briefing, to the choice of dive sites, to dinner service, to the quality and thread count of our Egyptian cotton bed sheets. We never stop stressing over the details. We never stop trying to do even better.
Happy Crew, Happy Ship
A happy crew makes for a happy ship and the very best in guest experience. The men and women on our ships come from around the world and share your passion for Mother Ocean. Every one of our seventy crew and thirty-five shoreside support staff in Mexico and Canada are committed to doing the best they can for you, our guests, and that shines through like a bright beacon of happiness.
Choose from 4 stabilized, ISM safety certified ships
Canadian shipyard built from the keel up with a thoughtful design intended to support operations from the chilly current swept waters of Alaska to the equatorial heat of Clipperton Island. Recently lengthened to 132 ft, the Explorer was the world’s first SOLAS safety certified dive boat.
Nautilus Belle Amie
The “Belle” is our newest ship, launched in 2015. At 147 feet she is a big, beautiful and very popular liveaboard that is more like a small ship than a dive boat. Guests enjoy ultra-quiet rooms, spaciousness and comfortable, stabilized crossings.
Formerly the Undersea Hunter of Cocos Island and IMAX fame, the Nautilus UnderSea is one of the most beloved live aboard dive boats in the world. With a new full-width superstructure, enclosed dive deck and lengthened to 105 ft, the UnderSea is perfect for smaller groups of just 19 divers.
Nautilus Gallant Lady
Our new Gallant Lady is beautiful and combines the luxury of a Broward yacht with thoughtful liveaboard dive boat design. This 116 foot yacht features 6 large suites, accommodating 12 guests, and 1700 horsepower along with hydraulic stabilizers, speeding you wherever you want to go.

Today was our first day of diving here at Revillagigedo and it feel so good to be back on board. The Canyon at San Benedicto did not fail to impress once gain. The water was clear and a slight current was taking us on a westerly direction. Chevron mantas greeted us as we entered the water on the first dive followed by dusky sharks, silver tips, silky sharks, hammerheads, and more mantas.
