Best diving trip with best crew
This trip to Socorro felt so special, we had an amazing crew taking care of us underwater and on the boat, we were diving so remotely that it felt really unique, the dives sites are magical. Really recommend Nautilus as it’s a really safe company and crew members are really awesome!

Awesome crew, amazing diving, and well run operation.
Dolphins, hammerheads, tiger shark, mantas, and the wonderfully friendly crew. The food was good. The top deck can get a little fumey while motoring, so I'd encourage the boat to raise the smokestack or otherwise get creative with the exhaust fumes so that its more comfortable to hang out while motoring.

- The crew was absolutely wonderful, the diving and competence of the crew were excellent, and the boat operated like clockwork.

amazing crew that went above and beyond
Nautilus Under Sea is a very comfortable boat, with nice cabins, lots of storage space and very nice bathrooms in cabins. Diving deck organization was perfect, enough space for everyone, large table for cameras. The diving crew was very helpful, enthusiastic, and managed the diving part in an extremely safe and organized manner. Even when the diving conditions were difficult because of the weather, they expertly got everyone in and out of skiffs. All in all, amazing experience of diving with mantas, dolphins, Galapagos, silky sharks and other marine life, which is abundant in the Socorro.

Spectacular shark encounters
The almost 6m tall "Lucy" and another female of almost the same size, which were often very close to the cages. Sighting of a total of almost 30 different great white sharks. The information from the professional crew about the sharks and their distinguishing features was also great. This gives guests the opportunity to photograph a shark that has not yet been registered and to give it a name. The spectacular jumps of the sharks out of the water were also sensational.
- Recommended for
- A great experience to experience the great white sharks so closely, the warmth of the crew and the possibility of unlimited cage diving.

Amazing trip!
Overall, this was the best diving I have ever done. We had so many mantas, dolphins, sharks, whale sharks on every dive. The entire crew was friendly and helpful! I have a dietary restriction and the chef did a perfect job of accommodating me and the food was delicious. The boat itself is not the best, a little noisy and has treacherous stairs to the lower deck, I didn’t get hot water even one time in my room, and there was black soot/ash on the top deck that got all over my feet, clothes, everything. Despite this, overall amazing trip.

The ship and the crew made for a wonderfully delightful dive trip experience.
Of course, the CALIFORNIA SEA LIONS!!! Such beautiful animals. They are comfortable with divers and getting to experience them up close and personal is something i'll remember until my dying day.

- I can't say enough about the care that the crew showed for all of us on board. Everyone was incredibly attentive to my needs. The food, dive guides, captain and steward were, not only incredibly competent, but carried out their duties with a care to detail and fun loving attitudes. Really, a fantastic trip.
