The Undersea is a beautiful ship, full of character and history. Formerly the Undersea Hunter, this famous little ship is well known for 26 years of service to Cocos Island with the Undersea Hunter Group of Costa Rica, as well as starring in many IMAX films and other movies. The newest addition to Nautilus Liveaboards has undergone 2 massive refits, including stretching the hull by 20 feet, repowering, a new bow, the construction of a new full-width superstructure, and the addition of our requisite hot tub, al fresco top deck lounge and stability system. She is a beauty!
(Giant Mantas, Sharks, Dolphins & Humpbacks)
Socorro is all about amazing interaction with our favourite giant mantas. No other mantas in the world behave like this. We don't know why but we LOVE IT!! And the mantas clearly love us back. November and December boast the warmest water temps of the year in the low 80's. Aside from the usual interaction with mantas, dolphins and 10 kinds of sharks, this is the best time of year to see whale sharks in blue blue water and often excellent visibility.
(Cage Diving with Great White Sharks)
238 identified great white sharks and counting. Imagine descending to 30 feet and going face-to-face with our big toothy friends in beautiful blue water with typical visibility of 125 + feet. July and August is the best time to see large numbers of rowdy male sharks - we have seen up to 9 sharks at one time! The opportunity for diving is virtually unlimited between between our submersible, suspended and surface cages.
