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

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

The Quino gives divers the opportunity to visit magical destinations such as Socorro, the Sea of Cortez and the Baja Peninsula at a lower price without compromising the level of service and delicious food our guests have come to know on the Rocio Del Mar.

The Quino offers truly unique diving experiences including Citizen Science Expeditions, regular dive charters, as well as the availability for other unique private charters. We can customize a trip itinerary around the special desires of the charter group.

Sea of Cortez

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.

Southern Baja Safari

Explore the Sea of Cortez 

Season: 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!
