Nautilus Explorer

Seafari Explorer ext opt

The 116-foot (35-meter) all-steel Nautilus Explorer was custom built for the open-ocean cruising she does. Her itineraries include Socorro, Guadalupe, Sea of Cortez & San Benitos Island.

 A word from Dom :  "Mike Lever's operations aboard the Nautilus Explorer, the new Nautilus Belle Amie & now the Nautilus Under Sea offer the opportunity for adventure diving at the most thrilling pelagic destinations in North America.  Nautilus Explorer is sturdy, stable and well-appointed .... and one of the most sought-after vessels for trips to Socorro & Guadalupe.  Highly recommended." ..... Dominick Macan

Everything about the ship and the way she is operated is designed for your maximum comfort.  The Nautilus Explorer enjoys catering to more experienced divers looking for advanced and sometimes challenging liveaboard diving.

The vessel was custom built to be comfortable, stable & safe in heavy seas ... and offers a high level of personalized service and delicious fresh cuisine.

She has 4 decks, the top deck being exclusively a sun deck.  Below that you find the wheelhouse, the hot tub deck and 4 very large, superior cabins.

On the third deck is the dive deck with stations accommodating 24 guests.  Also, a 5-ton hydraulic crane, water level platform and reinforced steel deck permits the staging of white shark cage diving and supports film and scientific crews. 

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.  This is the perfect place to relax, browse through the library, download digital images on our dedicated PC and Mac computers and view them on a 42" plasma TV, enjoy an evening slideshow.

Nautilus Explorer has nitrox, is re-breather friendly and offers everything a photographer could wish for.


The beautiful dining room with large picture windows is separated from the lounge on the same deck.   Imaginative and fresh cuisine is one of the pleasures of the Nautilus. Soups are homemade; bread, pastries and desserts are baked onboard and there is always a choice of entrees and plenty of snacks (including some that aren't good for you!). You'll find a mix of both buffet and table service with a menu that combines North American &  European tastes with a touch of Mexico.  Most special diets can be accommodated with advance notice.

As if two different sun decks with lots of deck chairs, a really comfortable main salon plus a sparkling clear fresh water hot tub aren't enough, you'll also find 30 different microbrews, extensive wine list and a great selection of single malts in the ship's bar.

Travel & cruise logistics


You have two options for airports for your Guadalupe adventure.You can fly into the San Diego airport (SAN), and then proceed to the Nautilus San Diego Dive Center. Alternatively you can also fly into the Tijuana airport (TIJ).  From the San Diego Dive Center, you will depart at 7:30 pm for the approximate 2 hour transfer to the ship in Ensenada, Mexico. Alternatively, guests may meet the Nautilus team directly in Ensenada.

At the end of your cruise the ship normally arrives back at Ensenada at 2:00PM or a bit later. Guests who met the crew in Ensenada will be be transferred back to the airport in Ensenada. Guests who met them in San Diego will be transferred back to San Diego Dive Center or San Diego Airport. The coach typically arrives in San Diego by 7:00 PM. Please do not book return flights earlier than 9:00 PM.


You will fly into the San Jose del Cabo airport (SJD), and then proceed to the Nautilus dive center at the Tesoro Los Cabos in Cabo San Lucas. There you can leave your bags and then tour town and enjoy a nice dinner before boarding the ship. The crew works hard right up to boarding time to get the boat ready so please meet them at the hospitality suite and not at the boat. 

On the final day disembarkation is at 8.30am for transfer back to San Jose del Cabo airport (SJD). We recommend that you book your return flights for 10:00 AM or later.
