The world‘s finest diving

Nautilus Gallant Lady

The Nautilus Gallant Lady adds to the Nautilus Fleet & increases the spaces available to divers at Socorro and the Sea of Cortes. She's 116 feet (35 meters) but accommodates just 12 guests.

“Gallant Lady, completely refit in 2020, takes only 12 divers to some seriously exciting encounters with pelagic animals. Diving with only a dozen people is ideal in my mind & brings back happy memories of the Red Sea liveaboard I worked on in the ’80’s … but, the real excitement here revolves around all the marine life returning to the Sea of Cortez.  The Sea is alive again & well worth a visit.”

Refit & Ready For Action

Nautilus Gallant Lady has been totally refit to please the crowds.  The boat is topped by a crow’s nest, great for spotting animal movements. The bridge, located below the crow’s nest, is open 24 hours a day to guests and just behind the bridge, you’ll find the open-air sky lounge, featuring comfortable seating (sofa-style benches, lounge chairs & deck chairs).  This area is terrific for sun-lovers …. and for star-watchers at night.

On the large bow section of the main deck you’ll find the hot tub and cushioned seating. Inside on this level is a well-equipped dining room / salon with TV, DVD, sound system and plenty of CDs and movie.

The dive deck is at the aft and 2 suites are also found mid-ship on the main deck.  The remaining 4 suites are on the lower deck.

All of the Nautilus vessels are all known for their “good eats”.  On Gallant Lady you’ll enjoy a combination of Mexican and West Coast North American cuisine with home-baked snacks and drinks between dives.  On board is a wide selection of beer, wine and alcohol from the ship’s bar.  The chef will do everything possible to accommodate special dietary needs.  Please let us know your needs when you book.

Travel & Cruise Logistics

We recommend flying into Cabo San Lucas (SJD) the day before your trip.  We can recommend a hotel and the Nautilus staff at the Cabo Dive Center will be waiting to take care of you & will offer you a complimentary “warm-up” dive the day before departure.  The trip boards in Cabo San Lucas at 4:30 pm and returns to Cabo at 8:30 am.  Be sure you leave plenty of time to disembark, get to the airport and check in with time to spare if you are flying home.

The Sea of Cortez is a unique and different destination with its own charm. After being overfished and nearly ruined for posterity, this wonderful sea has made a comeback. Whale sharks are still resident seasonally off La Paz; the sea lions at Los Islotes were never impacted; the humpback whales still show up every winter; the huge schools of panamic fish are as abundant as ever before. Hammerheads have returned to El Bajo and Los Animas and mantas to La Reyna although they are not as abundant as before. Still, the numbers are encouraging. In the UNESCO Marine Park Cabo the fish have come back in droves and there is an excellent chance of seeing bull sharks here.
