What a Week!
Dan Hsieh, 11 July 2022This was my third Nautilus Liveaboard trip and perhaps the one I was most looking forward to. Although I got to see an entire Great White Shark breach from head to tail in the air in Guadalupe, and a pod of orcas kill and EAT a whale shark in the Sea of Cortez, I had […] -
I Couldn’t Have Asked for a Better First!
Sanjana Berry, 11 July 2022My first liveaboard ever and I couldn’t have asked for a better first! I must admit the diving was more challenging than what I am used to but with the help of the amazing dive masters onboard I was able to get through. We saw dolphins, oceanic mantas, hammerheads, massive lobsters, Silvertips, silky sharks, a whale shark, white tips, black tips – you name it and we saw it. -
Revillagigedo and the Nautilus Crew Deliver Again!
Nate Lipscy, 11 July 2022It’s hard to single out highlights from the trip. Curious mantas were circling our group for what seemed like forever, playful dolphins swarming us and getting so close my wide-angle GoPro couldn’t keep up. A tiger shark at Canyon! Sure, there were dozens of Silvertips and some big Galapagos sharks, but when a tiger shows up, that’s all you can talk about. There’s no such thing as a quiet dive at Roca, but throw in a whale shark and a dozen dolphins and it’s hard to get out of the wate -
This Has Been an Amazing Expedition
Graham Munro and Tony Burrows, 5 July 2022This has been an amazing expedition, Tony and I have enjoyed the many challenges that have occurred (every day is a school day). We have enjoyed every dive and each has had its own unique experience. Our wives have vicariously through our pictures enjoyed the experience too. -
Once in a Lifetime Experience!
Fernanda & Anderson , 5 July 2022Well… It’s hard to find the right words to describe these massive feelings of I made a dream become reality. Before came here, we had some challenges to win. Dive the first time with sharks, 24 four trips to the dive site, and our first liveaboard. But now on the way back to Cabos I can say, it was a ONCE IN A LIFETIME EXPERIENCE! That easily can become two or three…

Airborne
At first, we didn’t really pay much attention to it, but after zooming in with my telephoto, I told Katie that I did not see a boat, and she quickly turned the plane to go check it out. As we got closer, to our surprise, we could then tell clearly that it was a megapod of dolphins. Hundreds and hundreds of them swimming in unison quite quickly headed up north towards Espiritu Santo Island.

Misty Blow Sunsets in the Sea of Cortez
There is nothing more fascinating than witnessing one of nature’s most spectacular sights. Whales! And there’s no better place than the majestic waters of the Sea of Cortez.
We have been fortunate to spot whales pretty much every day since our liveaboards started this season. Scouting this area alongside Katie (our Citabria pilot) we have discovered a couple of secret spots to encounter these humble giants.

What We Know About Killer Whales’ Diet in the Sea of Cortez
They seemed curious about our boats, circling them closely. Our guests from the Gallant Lady had a blast with them; we witnessed spy-hopping and majestic breaches, and the coolest thing was watching them feeding on a mola mola and sharing it amongst the group!

Our First Week with the Spotter Airplane Supported in the Sea of Cortez!
We were fortunate enough this first week to find whales pretty much every day: pairs of mother and calves of humpbacks breaching out and playing, blue whales, fin whales, and even a gray whale! Aside from these, we were surprised to have found a couple of pregnant whale sharks as well! Pods of dolphins and mobulas aggregations are in our daily sightings.

What Happens in La Ventana, Stays in La Ventana
Thanks to our spotter plane, we are now able to spot them quite easily, they normally congregate in groups of up to 10,000! We notice they are more active and breach more often when the sun goes down, we call it ”the sunset show”. One of the coolest behaviours Katie and I enjoy watching is the courtship behaviour, when a small group of males chases a female, she often times try to be evasive twisting and turning in different directions while the males mirror her movements, from above it looks like a beautiful slow-motion dance.
