    Day is beautiful, super clear skies. We did our check out dive at Fondeadero, dive was okay. For our second dive, The Canyon was the place, and smiles and good comments started to come. Guests loved it, some saw 50+ schooling hammerheads according to divemasters. Also they had a black and a chevron manta going around the divers, the galapagos and silver tips were very active too, some also saw rays on the bottom just resting as well as the white tip sharks. The usual cast of fish is always there, it is just that we don’t mention them, but the schooling horse-eyed jack, the clarions, flounders, octopus and a lot more.

    Jaw-some times at Roca Partida. In the past weeks we have been truly blessed with amazing dives at the rock, even seeing humpback whales breaching in the distance. This week was no different. So many sharks around. With a mild current from the north it is easy to kick into the split region and just hang in mid water with all the jacks and creol fish. We had around us at least 10 galapagos, 4 really fat silvertips and closer to the rock dozens of whitetips swimming together. Hammerheads swim into the mix sometimes and it’s been easy to find the school of about 30 as well. Just a bit into the blue and there they are!! 30 hammerhead sharks cruising together! They let us come quite close too. Absolutely beautiful!! And as we swim back to the rock, 2 chevron mantas are there to greet us.

    Our third dive we tried our luck at “Parientes Rock” where we saw the playful black manta the other day. Besides yellowfin tunas, lobsters, stingrays and one hammerhead, we didn’t see any manta this time. Back in the skiff, we were told a group of pilot whales just passed by. We managed some short moments snorkeling with them. There were several females with their calves swimming closely together. The fourth dive “El Cañon”, we didn’t expect to see more than the other day. We were completely wrong! On our way to the cleaning station, a manta showed off and circled us repeatedly. He came an arm’s length to the divers, made eye contact, and moved slowly for the next loop, it was breathtaking! Even the cleaning station was busy this time: silvertips, whitetips, Galapagos sharks and even a Tiger shark has been spotted. In the distance, a hammerhead was passing by. What a last dive, it couldn’t have been any better!

    This was one of the best diving trips that my family and I have ever gone on. The ship was incredibly comfortable and clean. The food was fantastic with a great variety and a lot of fresh fruit and vegetables. The crew and divemasters were incredibly friendly, knowledgeable, and made us feel at ease underwater. And the diving was absolutely incredible. We will for sure be back!

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.

We never stop stressing over the details. We never stop trying to do even better.

This is the trip of dolphins.

The Mantas spread the Love

Yesterday weather conditions invited us to visit Roca O´Neil, not every trip we are so lucky. Once again, we were the only dive boat around to enjoy the site. One after another all groups drifted along the wall with the sweet current mesmerized by the gorgeous lava formations, the arches and the chimneys, but most of all the cheeky mantas, going from on group of divers to the next, spreading the love equally without engaging for too long with any.
