The Nautilus Gallant Lady is part of the Nautilus liveaboard fleet. The 166ft luxury yacht caters to just 16 guests in 6 large suites. Cabins are located on the lower and main decks: 5 Superior Suites and one larger Premium Suite are available. Each room features individually controlled AC, a California King or two double beds, ample storage space, and private en-suite bathrooms. The Gallant Lady has been thoughtfully designed with plenty of comfortable social areas to unwind. The sky lounge with a hot tub on the top deck is the perfect place to enjoy a cocktail at the end of the day, and the sundeck is a great place to relax in-between dives. The main salon and dining room feature a fully stocked bar and wrap-around views. The onboard chef prepares a fusion of fresh Mexican and West Coast North American cuisine, and all dietary requirements can be catered for with advance notice.

Based in the Sea of Cortez, once called 'the aquarium of the world' by Jaques Cousteau, the Nautilus Gallant Lady offers year-round diving to 2 exciting destinations. From May-October, the Gallant Lady liveaboard is based in the northern Sea of Cortez at Bahia de Los Angeles. This area is home to the largest aggregation of whale sharks in the Sea of Cortez, as well as a large number of sea lions. Lucky divers may also get the chance to see the Humboldt squid at night!

From September to December, the boat moves further south to the Cabo Pulmo marine park, which has thrived over the past years. Referred to by some as a 'mini-Galapagos,' Cabo Pulmo offers regular sightings of bull sharks, tiger sharks, sea lions, huge schools of fish, and even manta rays.

The Nautilus Gallant Lady will deliver a Mexico dive liveaboard to remember whichever trip you choose.

A week of highlights

I experienced several firsts- bull sharks, eagle rays, mobula rays, and sea lions that interacted all day! The boat was very comfortable and the staff went above and beyond to guarantee a memorable week.

Diving in Cabo Plumo

We had some issues with our room and both Capitain and Nautilus ultimately did right by us. I would change few things... Diving in Winter even in cabo has its challenges..but even when sun sets early diving was very close to each other...i rather have a dusk dive. this way allows body to warms up before every dive. Food was good but I think more vegetarian verity for vegetarians would be good everything else was perfect

A cruise rich in emotion thanks to the crew, encounters with magnificent wildlife in an exceptional environment

The best was snorkeling with killer whales, playing with sea lions, meeting with a seahorse, octopuses, blenny fish

Once in a lifetime

Amazing, luxurious boat with the best rooms and best crew ever — who all went above and beyond and so patient and accommodating on EVERY front. Yummy food too. Best part surely was we got super lucky with wildlife, aside from regular mobulas and dolphins and sea lions, had nearly 2 days of mind blowing orca interactions, dove in countless times with 2 pods of total 14 orcas, witnessing them hunting dolphins even. Also hung out w a Bryde’s whale on our last day who stuck around for 6 hours and breached 17 times.

First and foremost, the crew went above and beyond at every opportunity. I can’t think of anything more they might have done for us. The diving highlight was certainly the seal lion interactions. Playing with the babies was the experience of a lifetime. The reef diving was also nice. The food was never ending and delicious. I wholeheartedly recommend Nautilus.
