First Time on a Liveaboard, and Definitely the Trip of a Lifetime!
Judy, 30 August 2022First time on a liveaboard, and definitely the trip of a lifetime! From the thoughtful and caring service of the crew to the clean and spacious boat, and of course the highlight of the trip – diving with all the amazing creatures, it was a trip to remember! As relatively less experienced divers, the divemasters were ready to accommodate and help out in whatever way they could to make the diving as safe and enjoyable as possible. Swimming with multiple species of sharks, and mantas, and being s -
We Had Such a Jaws-Some Experience
Byron, 25 August 2022This trip was a trip of a lifetime!!! We saw an endless supply of sharks, mantas, breaching whales, and even several dolphins. I’ve been around whales for quite some time, but I have never seen a breach, and we saw a mother-calf breach multiple times between our dives and even cruised by our skiff after one of the dive groups saw them underwater. We had such a JAWS-some experience. -
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
