The Nautilus Explorer Costa Rica is a 40-meter/132-feet-long liveaboard that takes 27 guests in 13 suites and staterooms on diving trips in Costa Rica. There is a Premium suite with a bedroom, a lounge, and a full-size bathtub in the bathroom. The 3 Superior Suites 3 have large windows, desks, wardrobes, and ensuite bathrooms and showers. On the lower deck, there is triple and 8 double staterooms: 6 with two beds side-by-side beds, and one with twin beds, all with ensuite bathrooms and showers. The triple stateroom has a bunk bed, a double bed, and an ensuite bathroom. The dining room, the main salon, and the dive deck are on the main deck. On the Wheelhouse deck is the hot tub where guests can relax between dives and enjoy a drink while admiring the view.

The Nautilus Explorer Costa Rica offers diverse activities, including diving, kayaking, sunbathing on pristine white sand beaches, and venturing into Costa Rica’s vibrant rainforest. Some local wildlife includes monkeys, lizards, parrots, toucans, hawks, sloths, and iguanas. There are also many fascinating species guests can encounter in the water, including dolphins and, with a bit of luck, even Manatees. Summer offers exceptional visibility for diving, and it's the perfect time to witness the grace of humpback whales and nesting turtles. The knowledgeable guides show guests dive sites such as Bat Island, renowned for its bull sharks, and Catalina and Cano Islands. As we venture into uncharted territory, we may spot local crocodiles. After the adventures of the day, enjoy stunning sunsets during cocktail hours. A once-in-a-lifetime adventure.
