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.

One Liveaboard feedback for “MV Argo”

  1. We had an unforgettable week scuba-diving on Argo!
    We’ve dived in many beautiful places including the Tuamotu archipelago in French Polynesia. But nothing compares to Cocos Island when it comes to sharks. We’ve never seen as much scalloped hammerhead sharks. We admired them during all of our 21 dives apart from 2: the check dive in a lovely coral garden, and a dive on Big Dos Amigos, where we saw a tiger shark. Galapagos sharks are numerous as well. And we could see some black tip sharks, one whale shark, and two tiger sharks! There are so many white tip reef sharks that you ignore them completely. Apart from sharks, there are some impressive schools of jacks, some massive tunas, barracudas, frog fishes, marble rays, eagle rays, boxer crabs, just to mention a few.
    Security is paramount. All divers are equipped with GPS emitters, lights and whistles in case you are taken away by current. Undersea Hunter developed an astute defense pole to which you can add a bullet firing top in case of an unlikely attack from a tiger shark. The dive guides are very professional and caring. The dive sites have lines to facilitate the access to submerged rocks in big currents. You have space for your photography gear. The skiffs used to get to the dive sites are comfortable and speedy.
    We were thrilled to dive with Deepsee submarine. We greatly appreciated the professionalism of our pilot Federico, whose knowledge and kindness made our exploration highly entertaining and captivating. Time flied during the whole journey! We started with dolphins at the surface. We enjoyed looking at crabs, eels, frog fish, brotulas, groupers, and many strange invertebrates. At 300m depth, we were so excited to spot an unknown fish species, that needs to be checked by a scientist for identification.
    The boat is large with comfy cabins with lovely marine paintings. We had the manta ray cabin. On the first night in Cocos, we were annoyed by a high pitch noise due to a generator. As soon as we mentioned it, they found a solution to stop it. More generally the whole team was very kind and caring. You can feel that all team members are happy and love their jobs. The food was good. On top of that we had a very friendly group of divers, which allowed for a lot of captivating conversations.
    We will be back!
