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.

White shark express
The crew went out of their way to make your experience a fantastic and memorable one. The opportunity to see multiple white sharks from up close was amazing. There was never a wait to get into a cage so you could essentially soak as long as you wanted to! Would recommend this trip and boat.

Great White Shark Diving at Guadalupe Island
Full points for the crew, food. and the diving experience. It is well deserved. The cabin comfort didn't rate full points because we had issues with the central air in the cabins below decks. Our room was too hot while someone else was getting all our cold air. We were offered and accepted an upgrade to the premium cabin, so it ended well for us, and the captain said they will work to resolve this problem in the future. As someone with thousands of dives around the world, and having seen thousands more sharks, I wasn't enthusiastic about diving in a cage, but I also hadn't seen great white sharks before. After this experience, I would do it again. I averaged 4 to 5 hours a day in the cages watching the great white sharks, and they didn't disappoint me. They were very photogenic, with lots of photos and videos made. It is an experience even the "hardcore" divers should try. Bring a drysuit if you have one, or the thickest wetsuit you have. The water is cool, and you'll be able to stay in longer and more comfortably.

- 1. Seeing the great white sharks. 2. Seeing Bullet, a very large female that hadn't been seen in the last ten years. 3. Up close encounters with great white sharks.

Great if you like big fish
Good trip for more experienced divers. A lot of blue water and current but most of the time it is worth the wait and struggle because you see a lot of big fish you only find on some other places. Boat has been refitted and is nice and has good standard. Very nice crew, DMs are experienced and won‘t look after you all the time. Trip to the islands is long and exhausting though especally if the swell comes in. Overall a very good trip to check off some large pelagic fish and sharks.

Gran Experiencia a Bordo
El encuentro y la interaccion con las mantas gigantes, es una experiencia unica!!! Pero no ha de ser de la unica vez, ya dan ganas de retornar apenas termina el ultimo buceo!
- Recommended for
- Lo mejor del crucero fueron los buceos, magnificos todos, siempre con avistajes maravillosos de mantas, tiburones y mucho mas. La calidad de la atencion a bordo por parte de toda la tripulacion, muy esmerada y esforzada siempre, y por ultimo el grupo de buzos con el que compartimos el crucero, la pasamos super bien

Not for me.
My trip advisor review...I went on an 11 day Liveaboard, under the sea. Unfortunately I got sick from the get go and it didn’t let up, back from the Liveaboard I still don’t feel well, I only did 3 dives and found that because I wasn’t well to dive, I was basically an outcast, I tried to be polite but because it was a problem I felt very uncomfortable on the ship and felt very upset, on informing the operator at the end, they clearly weren’t interested either. The boat at one point coughed up soot from the engine exaust over me and woke up covered in ash, this made me sick again. I question how environmentally friendly this boat is. I don’t consider myself a difficult person, but I felt I was around the most uncaring people and it caused me a lot of pain. I will definitely do more research into my future Liveaboards and go with a more environmentally friendly group that is not just concerned with money making. I would not go with this company again, or recommend to any else.

A pretty unique experience
The dive guides are very good, especially Rodolfo. They spot the sharks, mantas and dolphins usually before the group see's them. The food was also good, with no complaints of any illnesses. The boat and crew has a good attitude to safety and give some quite lengthy but essential safety briefings. My 2nd trip to Socorro, but hopefully there will be many more to come!
- Recommended for
- Wild dolphins that are tame and are not scared of divers. Manta's which love to hang around for most of the dive and interact with divers. Uncrowded dive sites with hardly any other dive boats around.

An outstanding experience, I'll definitely dive with Nautilus again.
Sea lions! Who knew they were so much fun under water :) Good viz and great diving all-round, covering an excellent range of sites (and more dives than advertised - 16 vs the 12). Sundowners and beers (from a very well-stocked bar) under the stars. All made extremely easy and enjoyable by the wonderful staff.
- Recommended for
- The staff were all fantastic, friendly, extremely professional but also engendered a relaxed, enjoyable experience. The vessel is in good repair, well set up for diving and relaxing. And the trip is all made very easy and efficient by the shoreside support.
