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.

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.

Sea lions & whale sharks in the Sea of Cortez!
I just returned from an incredible week in the Sea of Cortez aboard the Nautilus Undersea. The diving was just incredible and definitive trip highlights were diving with the sea lions and snorkeling and swimming with the whale sharks. The boat crew were extremely friendly and worked nonstop and we had 3 amazing dive guides throughout the week. We learned quite a bit about the Sea of Cortez through various nightly presentations on board and also had fun swimming and kayaking during surface intervals. I can’t say enough about our chef as all the meals were fantastic and our hostess was so friendly and always smiling. What an incredible week!
