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 Liveaboard Experience with exceptional diving
I would recommend this trip to any diver interested in exceptional diving.

- The wildlife encounters were amazing, from pelagic mantas on almost every dive, to 5 different types of shark, some huge, and a school of 1000+ 50 kg to 150 kg yellow fin tuna. Amazing!. The crew was amazing. The captain's leadership in delivering customer satisfaction. From driving zodiac skiffs, to clearing tables on occasion, nothing escaped his attention to detail. All efforts directed at delivering the best experience possible for the divers. The passengers gelled rapidly, with participants from Argentina, Brazil, Switzerland, Austria, Belgium, Taiwan, Canada and the U S.

Incredible week - go here to see the BIG stuff!
Had an awesome week! The best pelagic big stuff diving I've had anywhere in the world, mantas on every dive, hammerheads, close encounters with dolphins, tons of sharks and humpback whale watching from the surface. The crew was great, and were willing to take us on a launch between dives to go snorkeling with a school of false killer whales. The captain coordinated with other boats so that we were the only boat at Roca Partida (having multiple boats would have reduced our dives there).

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!

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.

Excellent
Diving trip done in August 2025. We really enjoyed our time on the Nautilus Undersea. Crew was amazing and worked very hard at making we were happy and comfortable. Safety of guest was taken very seriously. Well organized. Swimming with Whale Sharks was great. We did one night dive and it was the best night dive we have ever done so far. Boat is a bit old but we were comfortable. No complaints at all. We are already planning our next dive trip in Socorro with them.

unforgettable experience
The underwater world has surpassed everything seen so far. The crew on the boat was super friendly, helpful and took care of the well-being of the guests. An all-round successful trip. Come back on this boat, the number of guests is ideal, so you don't get in each other's way under water.
