    This is the trip of dolphins. April 12, 2019 - - We started off jumping close to the wall. While swimming towards the receiver, several whitetips crossed our way. Suddenly, a hammerhead appeared in the blue and disappeared as fast as he came. When swimming to the inner side of the lava finger, several whitetips were circling between the rocks, curious to find out what these black things were, making these strange bubbles. Almost as the hammerhead, a big manta, followed by blind passengers below him, showed up swimming gently above us and disappeared again in the blue.

Our Values – Our Culture

Nautilus boats are built for Safety
Built for Safety

Most divers would be shocked if they knew what was going on in the engine room and below decks of many liveaboard diving ships. Safety is not something to ever take lightly. We live and breathe safety with obsessive compliance to our Safety Management System under the watchful eyes of our external auditors. See our passenger and safety certificates here.

Our commitment to safety >

Luxurious Liveaboard Diving
Excellence in Guest Experience

Captain Mike has led the way for the last twenty-seven years in consistent and relentless obsessive attention to detail, and making every trip as excellent as possible. That attention to detail shows up everywhere, from each dive briefing, to the choice of dive sites, to dinner service, to the quality and thread count of our Egyptian cotton bed sheets. We never stop stressing over the details. We never stop trying to do even better.

Mobula Experience, the epic wildlife migration you’ve been waiting for!

Take a deep breath. Jump in the water. Open Your Eyes. Here they are, before you. Hundreds of Mobula rays elegantly flapping their wings and swimming alongside each other in mesmerizing circles. These rays aren’t just a treasure to see underwater, they’re also quite the aerobatic performers, and can be seen leaping high into the air before crashing through the surface with a loud bang!

Today was our first day of diving here at Revillagigedo and it feel so good to be back on board. The Canyon at San Benedicto did not fail to impress once gain. The water was clear and a slight current was taking us on a westerly direction. Chevron mantas greeted us as we entered the water on the first dive followed by dusky sharks, silver tips, silky sharks, hammerheads, and more mantas.
