We all carry the awareness that while we are privleged to have experienced the wonders of the underwater world, we also carry the responsibility to protect it. That is why Quino el Guardian was created. Quino was once a fishing vessel and was redesigned into a ship whose sole purpose is for scuba diving and scientific research.

We created Quino because of the time we spent with marine biologist groups on our sister ship, Rocio Del Mar. Our experience with them was so incredibly rewarding that we wanted more. We believe that we can make the world a better place one diver at a time.

Quino gives divers the opportunity to visit magical destinations such as Socorro (Archipielago de Revillagigedo), the Sea of Cortez-Midriff Islands, Sea of Cortez-Explore Baja Expeditions and the Southern Sea of Cortez (Southern Safaris).  We offer the same diving along with the same amazing crew and delicious food our guests have come to know on Rocio Del Mar at an incredible value.

Quino el Guardian offers fun and exciting scuba diving experiences including our truly unique Citizen Science Expeditions. Quino is available for individuals, one-half and full charters as well as custom private charters. We can design a trip itinerary around the special desires of the charter group.

The Story of Quino


Join us on Quino for the 3 C's:  Casual, Comfortable & Camaraderie! 

Quino El Guardian is the "brother" ship of Rocio Del Mar. Quino is a 90' boat that was originally a Northeast commercial fishing vessel. Quino was brought to Mexico in 2015 and completely redesigned for research and exploration and recreational dive adventures.

Quino gives divers the opportunity to visit magical destinations throughout Mexico while offering guests an incredible value without compromising the level of service and delicious food our guests have come to know on Rocio Del Mar.

About half of our trips on Quino are Citizen Science Expeditions giving divers the experience of working side-by-side with scientists as they study sharks, mantas, reef ecology, marine biology and more. Activities include animal tagging, identification, DNA sampling, and daily presentations on migration, reproduction, conservation and daily observations.

Quino is available for individual bookings, half and full charters as well as custom private charters.

Join fellow divers and a renown scientists and take your underwater adventure to a whole new level. Learn about the ocean and its inhabitants by working side by side with scientists as they study sharks, giant manta rays, reefs, invertebrates, mammals, and all aspects of our undersea world. Experience Quino el Guardian's Citizen Science Expeditions and dive with a purpose!

In the end we will conserve only what we love; we will love only what we understand; and we will understand only what we are taught.

We know Mexico better than anyone else! 


Where the Wild Things Area

Season: November - May

Also known as Archipeilago de Revillagigedo, these are a group of four volcanic islands in the Pacific Ocean 250 miles off Baja Mexico's southern shore known for their unique ecosystem. The islands are home to many endemic plant and animal species and Socorro island is the most diverse in flora, fauna, and topography.

These islands are a spectacular magnet for the largest ocean pelagic animals in the world. Animals include schooling hammerhead sharks, tiger sharks, friendly bottlenose dolphins, silky sharks, Galapagos sharks, clouds of jacks and barracuda, tuna, wahoo, and oceanic white tip sharks. Yet it is the manta rays that are the claim to fame. Humpback whales can often be mid-February through mid-April and whale shark season is November-December and May.

The World's Aquarium 

Season: July - October 

Easy to get to yet impossible to forget! With clear, deep waters, abundant sea life, golden sandy beaches and inspiring vistas, the Sea of Cortez - known as the Gulf of California - is a breathtaking destination for scuba diving, snorkeling, sailing, boating, and exploring diverse marine creatures. Legendary diver Jacques Cousteau described the Sea of Cortez as the "world's aquarium". Dive on untouched walls and reefs abounding in marine life. Encounter large and small whale species, jumping Mobula Rays, turtles, and sea lion colonies. Hike and explore remote uninhabited islets and snorkel with Whale Sharks at Bahia de Los Angeles. Dine under the stars in a calm anchorage and revel in the remoteness that is the Sea of Cortez. No planes and no other boats … only you, your boatmates, and the animals. Come with us and experience the magic that is the Sea of Cortez.

Sea of Cortez Schedule


Explore the Southern Sea of Cortez

Season: March & October

Once or twice a year, we offer this very unique itinerary where we will be at the right place at the right time to see blue whales, bull sharks, and flying Mobula rays. Go on day and night dives at remote islands that are inaccessible without a long-range liveaboard like ours, encountering the abundant sea life of the Sea of Cortez. We will also explore popular dive sites such as Los Islotes where we’ll encounter friendly sea lions, and El Bajo, which is known for its schools of hammerhead sharks. Included in our itinerary is a day spent diving in Cabo Pulmo National Marine Park, the only living reef on this side of the hemisphere. This is a voyage you don’t want to miss!

Southern Safari Schedule


Dive with a Purpose! 

Quino el Guardian offers a truly unique experience – our Citizen Science Program. These trips include a marine biologist specializing in subjects such as sharks, mantas, humpback whales, marine mammals, marine ecology and more.  In addition to the diving itinerary, guests can participate in hands-on activities such as animal tagging, identification, fish/animal counts, etc. Divers can be involved as much or as little as they like including hands-on research and presentations.

What is Citizen Science?


Through our Citizen Science program divers will learn about topics such as animal identification, animal tagging, animal behavior, migration, reproduction, study of individual species, census monitoring, reef health, human and climate impact studies, plankton tows and study, conservation, and free diving expeditions.
