The Undersea Hunter is a converted steel hull research boat. It is a small vessel that sleeps only 14 guests in comfort and has become an icon of the diving scene at Cocos Island, run by the most experienced scuba operator in Cocos.

Cruise: 9 knots
Divers: 14
Enriched air nitrox is available here
The MV Undersea Hunter for your Cocos diving safaris

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 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 free laundry service, a dining area and a sun deck for soaking up the Costa Rican sun. Its custom-built outrigger-mounted stabilizing system makes the boat one of the most stable in the industry.

The MV Undersea Hunter runs Cocos diving safaris all year round with trips being either 10 nights or 12 nights in duration. As a great perk at this shark Mecca, nitrox is free of charge to those divers that are suitably qualified. You may also be able to experience an incredible dive in the DeepSee Submersible that is housed on board the sister ship MV Argo. Argo must be positioned at Cocos Island at the same time as your cruise for this to be possible.

To ensure your safety, each guest is issued with a personal diver locator, clipped to their BCD. All diving at Cocos is made from large and well-equipped twin engined fiberglass skiffs, fitted with roofs to shelter you from the Pacific elements. Cocos is a remote, dream scuba destination and it is good to know that you are in such safe hands as those of the experienced crew of the Undersea Hunter.
