MV Argo dive boat review

With world-class facilities, world-class vessels and world-class diving, the Undersea Hunter Fleet are one of the key dive safari operators visiting the amazing Cocos Islands. MV Argo is the newest vessel on their stunning fleet and the sister vessel to MV Sea Hunter and MV Undersea Hunter.


The Cocos Islands, off the coast of Costa Rica, were designated as a protected marine park back in 1978. Today, still equally impressive, they remain home to some of the most impressive pelagic life on the planet. There is a great diversity of marine and still the chance to see large groups of sharks and rays in their natural habitat. Some experts also speculate that during the correct season whales utilise the Cocos Islands to take shelter from the open ocean, congregate and give birth. With in excess of 25 endemic fish species, including such special species as the red-lipped batfish, the Cocos Islands are a wonderful playground for experienced divers.



MV Argo is the newest addition to the fleet. She was built in 2008 to be a hybrid of luxury liveaboard and working ship. The owners, Underseahunter Group, consider her to be the culmination and amalgamation of all their knowledge and experience running vessels in these waters over the past years. Argo is 129ft/39m long, 26ft/8m in beam and – with her strong steel-hulled construction – weighs in with a displacement of 205 tons. She’s sturdy, safe and ready for action! And, with a powerful 850hp CAT motor she’s capable of powering to and from these famous islands at a cruising speed of 10 knots.

Inside the Deep See Submersible


Yes, Argo has it’s own submersible – ‘Deep See Submersible’. ABS approved and certified with a Schilling Orion robotic arm; it’s capable of taking 3 persons in this 1500ft/500m rated submersible.


And, to record all of these amazing experiences, there are camera stations and lots of charging points to ensure you don’t miss a thing.





The itineraries generally take the vessel to Cocos Islands. The islands are a considerable distance offshore and a 32-36 hour transfer once aboard is typical.


Voyages are typically 11 days/10 nights. The facilities are world class and, combined with the offshore travel time, not inexpensive. As a consequence, expect to pay around EUR5,665 for this length trip. This equates to EUR514/day. Please note that this does not include some extras such as port/marine park fees and equipment rental. Please contact us for further details.
