Rocio del Mar

After three years of meticulous planning and construction, the 110-foot Rocio del Mar had its maiden voyage in May 2010 in the gorgeous waters of the Sea of Cortez. It was built by divers for divers, and the fact is evident when onboard. There are ten double staterooms, all with private bathrooms, air-conditioning and picture windows. The maximum number of divers is 20. Eight of the cabins are located on the main deck and feature angles single beds, and two cabins on the second deck have a full lower bed and an upper bunk. A spacious dining room serves tasty meals that focus on local fresh ingredients, and an entertainment area has a flat-screen television, DVD player and CD player. The top deck has plenty of room to spread out and watch the whales and dolphins, and enjoy a barbecue.

From July to November, Rocio del Mar dives the Sea of Cortez. Whales, whale sharks, mantas, mobula rays, and sea lion colonies inhabit these waters with colorful corals and numerous reef fish, nudibranchs and schools of pelagics. From November to May to boat moves to Socorro Islands to dive with the sharks. You can do up to four dives per day, and there are two zodiacs to serve three different dive groups at the same time. Rocio del Mar departs from Puerto Peñasco, about four-hour van drive from Phoenix for its Sea of Cortez itineraries. The city is getting its airport late 2010 making getting there a breeze. For Socorro Islands, the departure port is San Jose del Cabo. The boat offers Nitrox.

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, whale sharks, jumping mobula rays, and sea lion colonies. Hike and explore remote uninhabited islets. Dine under the stars in a calm anchorage, socialize with your shipmates and make new friends. Then melt into a luxurious bunk in your own finely appointed cabin with private bathrooms and hot showers. All in a day aboard Rocio, combined with personalized service to enhance your live aboard safety and fun. Dive into your dreams and see what Sea of Cortez diving is all about.

The Revillagigedo Islands (also Revillagigedo Archipelago or Islas Revillagigedo) are a group of four volcanic islands in the Pacific Ocean, known for their unique ecosystem. The islands are home to many endemic plant and animal species, and are sometimes called Mexico's "little Galapagos".  Socorro island is the most diverse in flora, fauna, and topography.

The islands lie 250 miles off Baja Mexico's southern shore. When embarking on a trip to the Socorro Islands; possible destinations on the itinerary are San Benedicto, Socorro, Roca Partida and Clarion Islands.

These islands are a spectacular magnet for the largest ocean pelagic animals in the world. Schooling Hammerhead sharks, Tiger sharks, dolphins, silky sharks, Galapagos sharks, clouds of jacks and barracuda, tuna, wahoo, oceanic white tips sharks, whale sharks and mantas.

Mantas are the claim to fame for Socorro Islands; the island on which they seem to congregate the most is San Benedicto! The magical dive site called "The Boiler" is a submerged sea mount and cleaning station. More than a half dozen Mantas frequent this pinnacle regularly. The Mantas here are the friendliest I have ever experienced, they seem to enjoy the presence of humans. This is truly an exceptional place if you wish to really experience the Manta Magic.

Humpback whales visit during the winter months of January through April. This is a splendid time to hear the sound of the singing mating male escorts underwater. This destination can only be dived by a live aboard dive vessel. It takes approximately 26 hrs one way to reach the islands. This is an excellent dive destination for large pelagics due to the open ocean nature of the islands, which sometimes include currents and choppy conditions. The underwater topography consists of rocky outcroppings, boulders and some walls. There is not much in the way of coral as this is a cooler water destination.

The crossing from Los Cabos San Lucas to the Socorro Islands takes approximately 26-28 hrs. It is open sea, please be prepared in case we are faced with rough seas. There are several over the counter remedies that can help you. In case you have a propensity to motion sickness or are concerned that you might develop symptoms, please arm yourself with preventive measures before hand.
