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.

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).

Awesome crew, amazing diving, and well run operation.
Dolphins, hammerheads, tiger shark, mantas, and the wonderfully friendly crew. The food was good. The top deck can get a little fumey while motoring, so I'd encourage the boat to raise the smokestack or otherwise get creative with the exhaust fumes so that its more comfortable to hang out while motoring.

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.
