Nautlius Explorer


NautilusExplorer_©Nautilus Explorer_(1)The 117 ft Nautilus Explorer is custom designed for divers to the highest possible level of comfort and safety with a layout that utilizes every square foot of available space. The crew takes exceptional pride in keeping the boat spotlessly clean and running smoothly. Everything is first class and certified to the same exacting international SOLAS and ISM standards as the largest cruise ship

There is ample room to find a quiet place to read, chat, fill out your divelog or journal or work on editing the images you shot that day – whether in the separate dining room, main salon or one of the upper sundecks.



There is nothing like being under the stars in the sparkling clear fresh water of the hot tub after a day of diving or exploration. The main salon also serves as the ship's entertainment center with very comfy couches, a great library, a well stocked bar and select evening video showings, presentations and slide shows.

On Nautilus Explorer there are nine lower deck staterooms. Each has private heads with separate shower stalls, central air conditioning and measure 90 square feet. Six of the staterooms have side by side beds. Two have large double beds and additional storage area and the one triple occupancy suite has a double bed with two single bunks facing. The three superior suites on the hot-tub deck measure 145 sq. ft and have large exterior windows.They each have private facilities, a desk and either bureau or wardrobe. Two of these suites have doors that open directly outside. The third suite boasts a large flat screen TV and DVD player.

The premium suite is also located on the hot-tub deck and is twice the size of the other suites. It has a separate bedroom and lounge each with a large flat screen TV and DVD player, private facilities with a full-size bathtub and shower plus large private windows looking out on an ocean view.



The best way to observe great white sharks is to descend into their world and interact with them on their own terms in a natural way from Nautilus’ double-decker submersible cages. Conditions permitting, you can get out from behind the bars on the upper deck of 2 of these cages with only a single hand-rail between you and these incredible apex predators. Highly experienced divemasters in the submersible cages are always there to both “critter point” and ensure your safety. Guests on the Nautilus Explorer have 4 cages at varying depths to choose from providing the best way to see lots of “whiteys” up close and very personal.


Dive and interact with the friendliest giant mantas in the world. At Socorro, these giants choose to interact with divers. They come in very close, sometimes less than 1 meter, make eye contact and then swim along beside you, totally on their terms. It is very likely that bottlenose dolphins will also move in close and intimate to divers during your trip. Shark sightings are also very good at Socorro Island with common sightings of silky, galapagos, hammerhead, white tip and silver tip sharks. Humpback whale sightings and whale sharks are possible in season.

Sea of Cortez

It is always exciting to see hammerhead sharks and whale sharks when they pass through this area. There are lots of turtles in these waters and you will likely spot large schools of jacks, tunas, lots of small rays, garden eels and species of fish too numerous to count. The colony of California sea lions at Los Islotes are quite famous and will entertain you for hours with their playful underwater antics. These are very relaxing trips but be warned that there isn’t the same “edge” as voyaging out to Socorro Island with giant mantas and sharks everywhere. Sea of Cortez trips are very enjoyable and we liken them to swimming in a giant aquarium with an amazing diversity of animals in bath temperature water.
