Nautilus Explorer

The Nautilus Explorer is a large, modern, steel, ocean going SOLAS safari boat from Cabo San Lucas and Ensenada in Baja, Mexico. The company was founded in 1992 and Captain Mike Lever has been solidly at the helm throughout the company's evolution from our original 14 meter wooden 8 passenger Nautilus VI to our current state of the art luxury 37 and 41 meter "big white boats".

For a small ship, the 132 foot Nautilus feels “plenty big” (or so our guests tell us). There is ample room to find a quiet place to read, chat, or work on editing the images you shot that day – whether in the separate dining room, main salon or one of the upper sundecks. And there is nothing like a soak under the stars in the sparkling clear fresh water of our hot tub after a day of diving or exploration. The main salon also serves as the ship’s entertainment centre with very “comfy” couches, a great library, a well stocked bar and select evening video showings, presentations and slide shows.

We offer accommodation on the Nautilus Explorer to suit all preferences ranging from a luxurious premium suite on the hot-deck to a cost effective, mixed-gender triple occupancy stateroom on the lower deck.

When you set off on a trip on the Nautilus Explorer, you will experience "adventure" in every sense of the word. You will voyage out to remote volcanic islands in protected marine biospheres that very few people ever experience. Depending on the destination, you can either dive exciting sites in the Sea of Cortez or giant manta rays, wild dolphins and up to 10 different kinds of sharks at Socorro.

As of Jan 2023, the Guadalupe Great White Shark diving has been suspended indefinitely by the government of Mexico. The magical island of Guadalupe is 180 miles from the Mexico coastline. The coast of Guadalupe is 25 miles of rocky cliffs, but above this is dense forest, giving it the feel of an exotic, South Pacific destination. You can expect between 100 and 150 feet of visibility. We can literally see the sharks come in from beyond the anchor line. Nothing but clear, cobalt blue water.

Moreover, this experience isn’t limited to advanced divers. You don’t need to be a certified scuba diver to join us, although we recommend you take a Discover Scuba Diving course prior to your trip, and possess a strong in-water comfort.

All certified divers will have the opportunity for a minimum of three dives per day in the submersible cages—and your trip includes the opportunity for unlimited time in the surface cages. Divemasters are in the water during every submersible-cage dive to ensure your safety. Note that the surface cages open at 6:30 a.m., and diving in the submersible cages begins at 8 a.m. Both are available until dusk.

Our conservation efforts also continue at night when we kick back in the salon and identify who we spent the day with. And should you realize that you hung out with a great white shark not yet catalogued, yes, the naming rights are all yours.

Socorro Island is part of the Revillagigedos, a group of small islands off the coast of Baja California, Mexico. Dive sites include Socorro, San Benedicto & Roca Partida but may change due to ocean conditions. Our goal is to provide you with the best possible diving. It’s one of the reasons we stay committed to the Socorro Islands (a.k.a. the Revillagigedo Archipelago), well worth the full-day motor south from Cabo San Lucas. Volcanic in origin, these islands serve as an oasis amid the Sea of Cortez, 250 miles off the Baja Peninsula coast. The raw lava flows and active volcanoes in these islands resemble the lost world of “Jurassic Park,” which seems fitting as these outpost islands, including Roca Partida, beckon not just to giant mantas but to a host of big animals.

Your journey with us will include four dives per day (subject to weather and unforeseeable circumstances)—each an opportunity to encounter resident pods of playful dolphins. You may also see up to 10 varieties of shark: schooling scalloped hammerheads, solitary giant hammerheads, Galápagos, whitetip reef, silver-tip, silky, tiger and oceanic whitetips. The list also includes whale sharks and dusky sharks and on occasion even a thresher shark.

On most days, we enjoy visibility of 70 to 100 feet. When the current picks up, the ash from these volcanic isles can rise, reducing the visibility to 30 feet. For the wide-angle experience that is big-animal diving, this isn’t ideal. But, we’re still cruising one of the most pristine underwater environments—so we then choose dives where we’re closer to the reefs and marine life such as eels, octopuses and Socorro lobsters.

The onboard experience isn’t just about diving, but exploring this outpost that few people will ever visit. To that end, we carry kayaks and paddle boards. We offer an option for a night dive and a night snorkel. For added entertainment, we invite you to our “theater under the stars” for an open-air movie. It is our hope that the Nautilus team excels not only in surpassing your expectations of safety and excellence—but of fun and connection with the crew, the animals and the destination.
