experience, we know how to get you into the

sharks of Guadalupe Island, or unique
interactions with giant mantas, humpbacks and
10 types of sharks at Socorro Island. Join us for
incredible big animal encounters with the bonus

staterooms, hot tub and great food.
We custom built our beautiful Nautilus Explorer in 2000 with a laser focus on safety, luxury and the perfect dive boat configuration. Our guests enjoy stabilized crossings on the #1 boat that clients ask for.
Nautilus Belle Amie
Our Nautilus Belle Amie is a new build launched in 2015. This is the largest ship in our fleet and dwarfs her competition. Guests enjoy the ultra quiet rooms, extreme spaciousness and comfortable, stabilized ride.
Nautilus Under Sea
The Nautilus Under Sea is the former Undersea Hunter of Cocos Island fame. This brave small ship is one of the most loved dive boats in the world with a huge reputation and following. The Under Sea underwent renovations in 2016 and gained a full-width superstructure and premium suite on the upper deck.
