Highlights

Choice of 3 itineraries year-round
BBQ on board

The 27m Rocio del Mar liveaboard cruises through to the iconic dive areas of the Socorro Islands, Sea of Cortez, and Baja California and accommodates 20 guests in 10 comfortable staterooms spread over two decks. It offers divers the choice of 3 itineraries, depending on the time of year. All the rooms have private air conditioning, carpets, windows, storage space, and en-suite bathrooms. Meals and snacks are served in the large dining area in the lower deck's forward part and are available throughout the day. Al fresco dining and vegan options are available too. The boat has many relaxation spots, but the sundeck/top deck or the upper deck salon are favorites among the guests. Rocio Del Mar also has a spacious dive deck for storing all diving gear and a camera table for avid photographers.

Scuba diving off the Rocio Del Mar in Mexican waters is a treat. Socorro Island is part of The Revillagigedo Islands, often called Mexico's "Little Galapagos." The itinerary includes diving at San Benedicto, Socorro, Roca Partida, and Clarion Islands. These islands are a magnet for some of the largest pelagic animals in the world, with schooling Hammerhead sharks that come in the hundreds during their migration. Tiger sharks, dolphins, silky sharks, Galapagos sharks, schools of jacks and barracuda, tuna, wahoo, oceanic white tips sharks, whale sharks, and mantas are some charismatic megafaunas that can be spotted here. All dives are led by experienced divemasters who are enthusiastic about sharing their underwater world, and the diving takes place from two pangas or skiffs.

An amazing dive trip.
The journey out to the Socorros Islands takes time and can be a bit rough... but it is worth it! The diving was absolutely incredible. It was one of those rare times when reality was even better than what you see on Instagram or YouTube. The crew was fantastic - everyone was there to make your experience better. The food was excellent and they did a great job catering to individual dietary needs. I can't wait to go back!

weather conditions were a bit rough (windy) but everything was still amazing! we did mulitple dives at the same sites due to rough conditions at other sites but i thought was still nice because you get to know the area better, and the wildlife still changes. saw dolphins, mantas, tons of sharks, school of hammerheads, octopus, even a humpback whale although i think its late in the season for that. would highly recommend and hope i get to do this trip again some day

Epic adventure suppprted by an experienced, caring crew.
This trip was brilliant from start to end. The boat was a bit old, but very well designed and everything worked. The cabins have beds that intersect at the food (right angles) rather than bunks, so avoiding that claustrophic feel. Lovely hot showers. Spacious dive deck, which was really well organised. Good variety of food each day, freshly made.

Unbelievable amenities and crew!
The crew was very welcoming and seemed to work together seamlessly. They made sure you always had everything you needed. Dives were great, we got 22 completed by the end of the trip. Could see humpback whales from the boat, dove with dolphins, schooling hammerheads and countless manta rays who were very friendly. Trip of a lifetime!

Folicking Fun
The crew was excellent in helping us enjoy this wonderful ecosystem. When a superpod of common dolphins were close, after diving, they took us out in the Zodiaks (Pangas) to snorkle with them and see them up close. Great food, presented well with gracious accomodations for special diets. They were always courteous and kind, on the boat and in the water Also, sea lions

The diving experience was superb, the dive guides were knowledgeable and friendly, the crew was very helpful.
The biggest highlights were definitely the variety of life we saw - oceanic mantas, dolphins, schools of hammerhead sharks, and don’t forget the whipper snappers! The crew was very friendly and helpful, happy to be on the boat with us. The food was fantastic and plentiful. All in all a wonderful trip I would repeat in a heartbeat.

Easy and Interesting Diving in the Sea of Cortez
An overall great experience. I did the Sea of Cortez Mid Riff Islands itinerary. The boat, while not luxurious, has everything you need. The racks are comfortable and the food is excellent. The location of the galley in the hold is unfortunate but weather permitting we were able to eat top deck one evening and that was fabulous. The entire crew was incredibly friendly and helpful and worked tirelessly to create a good experience. Ship life is unpredictable, with unexpected repairs, weather, etc. and I thought the crew did a great job navigating whatever came and adapting to it. The Sea of Cortez is incredible with stark desert island landscapes and pristine beaches water. The dives themselves were excellent and approachable to wide variety of skill levels, offering a diverse range of topography and life including lots of sea lion interaction. I went in August when the water temp was at its peak and it was certainly warm, averaging 85F or more every dive. I would dive this boat and crew again for sure and am already looking at their Socorro itinerary for next year.

Unforgettable diving experience
We saw all kinds of shark species, dived often and long with dolphins and manta rays, got to know incredible dive sites like Roca Partida and saw three humpback whales underwater off Clarion Island. The Rocio del Mar is a great boat with that extra extra of stabilizers that make the long crossings very pleasant, an absolute plus over other boats. Food, team and guiding were perfect.

Great time on Rocio del Mar, they did a great job of taking care of us for Snorkeling!
Great job accommodating us for snorkeling. I was somewhat hesitant to book snorkeling (only) on dive boat. But, Rocio del Mar crew did great job accommodating us. We had snorkeling set up every day, with DM -- same schedule as scuba. Everything was top notch -- boats, staff, dive sites, etc. Highly recommended!!

I didn't come for the boat, I came for the diving and I was not disappointed!
I knew what the boat was going to be like, I didn't sign up cuz I like boats. :) The diving was great, so much to see! Vis wasn't great, but there was a lot of life, and for me, the water was warm enough (25c) that I didn't need to wear anything more than a rashguard. The mantas were breathtaking, and even from a distance, the tiger sharks looked menacing, and I was happy to keep them at a little bit of a distance from me. :) While all the crew were great, special shout-out to the chef, every meal was great, and many things I had never had before (still not sure what they all were!), were all very tasty. The boat itself is pretty much as presented in the images, it's "fine", didn't wow anyone, but also didn't present any problems. Oh, the mess is in the front of the boat, below the waterline, and while I didn't have any issues, there were nights when about 1/3rd of the divers didn't come down for meals due to sea-sickness issues. Some were delivered meals in their rooms... but you can hardly blame that on the boat I think. Other than that, the cabins are a bit on the smaller side, but not uncomfortably so.
