The Undersea Hunter was the first liveaboard to operate diving cruises to Cocos Island, now it returns there in form of Nautilus Under Sea! It is a converted steel hull research boat. It is a relatively small vessel that sleeps only 18 guests in comfort.

As both a diving liveaboard and a vessel for camera crew support, the boat is well equipped for underwater photographers and videographers. There is a personal storage system for underwater cameras, as well as a standard camera table with hoses, and rinse tanks.

Guests are accommodated in air-conditioned cabins with private en-suite bathrooms. Facilities include an air-conditioned saloon with full entertainment facilities including TV, DVD player and computer, a dining area, and a sun deck that features a hot tub and sun loungers where you can stretch out and work on your tan.

Comms features include wi-fi internet and satellite phone, so when you are far at sea around Cocos Island you can still stay connected. On the diving side, you will appreciate the spacious and well-organized dive deck with individual storage spaces. There is also nitrox available on board, as well as 15 liter tanks, and the Nautilus Under Sea is re-breather friendly. Cocos is a remote, dream scuba destination and it is good to know that you could be in such safe hands as those of the experienced crew of the Nautilus Under Sea.
