Seahunter in August
Diving in the Sea of Cortez was beautiful at the end of August. It was very hot in the area and the boat’s AC worked well. The water was very warm and there were hundreds of fish to see. We were on the Seahunter and the boat is very spacious and comfortable. There is plenty of space and storage in the rooms. The dive deck is large with a big charging table. The crew was very helpful and we had wonderful dives.

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.

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.

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.
