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.

Intense dives in a very friendly atmosphere.
Great week - the day of watching and swimming with the whale sharks was awesome! We saw several of them and to be so close to them was magical! The dives where the sea lions came to watch US! 😉

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).

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.

A must do trip for divers!
Even though the water was a bit chilly this liveaboard was a trip that I’d definitely want to do again and again. The crew worked together so well. It was like we were all a family by the end of the week. The food was delicious. The mantas and the sharks and the dolphins were incredible. At times I wondered if it was all real. The hot tub on top is a nice treat.
