    The MV Sea Hunter Liveaboard is a purpose built 35m dive liveaboard which was originally a commercial dive-support vessel serving the oil industry in the Gulf of Mexico. Because of this she is a superbly stable and robust vessel and also has ‘zero speed stabilisers’ which are lowered into the water when she is moored to give added stability, making the M/V Sea Hunter an ideal choice to take you on an amazing adventure diving the Cocos Islands of Costa Rica.

    Her renovations turned her into a very comfortable dive liveaboard, with underwater photographers in mind and all the facilities needed. The M/V Sea Hunter has 10 air-conditioned cabins with en-suite bathrooms for added comfort. She also has a study and lounge area, perfect for relaxing, editing photos or watching a DVD. The M/V Sea Hunter chef will provide varied, abundant and nutritionally balanced meals with a combination of American and Costa Rican cuisine. The bio-diversity of the Costa Rica is staggering, and due to the remote location of the Cocos Islands the diving is pristine. Marine life is abundant and divers can expect to see schooling white tip reef sharks, schooling hammerhead, dolphins, manta rays, sailfish and much more.

    A must-do expedition for experienced divers Cocos Island Expedition, Costa Rica in November

    Fantastic, the crew really go out of their way to make their guests feel special and appreciated. It is extremely expensive, but considering how remote the location is and how comfortable the boat is, it's understandable. Only recommended for hard-core experienced divers as the crossing to Cocos is long and bumpy. I loved every minute of it and was especially surprised how beautiful the cabins are (hand-painted individually). The general comfort level was a lot higher than I had expected and if I could afford it I'd definitely go back again.

    Great experience!! Cocos Island Expedition, Costa Rica in June

    As above, the diving was wonderful. Saw numerous hammerheads both far and close. Saw one whale shark (up close). But in addition to this, the diving was wonderful. Would highly recommend this trip. Only thing that was not up to liveaboard standards was the food. It was acceptable, but not what we would hope for. Divemasters and boat drivers were superb.

    Cocosfeeling mit Wiederholungscharakter Cocos Island Expedition, Costa Rica in October

    Immer wieder sehr gut organisiertes professionelles Seahunterteam mit hochseetauglichem Boot, perfekter Mannschaft mit guter amerikanischer Küche! Bogenstirnhammerhaie konnten wir bei unserem Trip im Oktober 2017 satt aus der Nähe betrachten! in 2009 konnte ich diese Tiere noch zählen. In 2017 war dies nicht mehr möglich gewesen!!! Tigerhaie zudem auch hautnah erlebt. Ich habe nach Cocos, wo dann eine weitere Malpelloexpedition zeitnah folgte, als Taucher mit mehr als 1000TG in den Weltmeeren nun alles erlebt. Cocostrips mit der Seahunter -die zudem auch ein Stabilisierungssystem- hat und den Wellengang sehr erträglich macht, sind und bleiben für mich ein Highlight was das tauchen betrifft Nicht ganz billig aber für das was geboten wird, seinen Preis wert! mit freundlichen Flossenschlägen Taucher Frank :-)

    Cocos - a dream destination repeated Cocos Island Expedition, Costa Rica in June

    This is my 2nd trip to Cocos seeing it was so mindblowing the first time. I was with a different operator last time, and in low season (apparently, but still incredible then as well). I must commend Seahunter for a really top notch operation, well laid out skiffs with room to move about, clean and extremely well kept boat and amazing food (healthy and varied). The lack of 1 star is due only due to rather japanese style hard matresses in some cabins...And I can normally sleep anywhere The crew also genuinly seemed to care we had a good time. Very friendly, engaged and interested. I will definitly return to this operator. Now the diving: hampered by really bad viz first part of the 8 days (This was a 10 day trip), but luckily it picked up. Rainy season really means RAINY, torrential rain throughout. No need for suntan lotion. Amazing big animal encounters, so if you like action diving with current, blue, and big game, this is for you. The island itself is also stunning, and just being so far away from the world, with Jurrasic park scenery, no mobil reception, letting it all hang out in tracky bottoms and watching the birds and the occasional thunderstorms...Well, lets say skip two trips to the Carribean and and save up to do this instead.It will blow your mind! As small end note: Its not easy diving though, so be prepared to be a bit bruised and battered. Very much worth the effort though, whalesharks, hammers a plenty, tigers, schools of trevally so big it must have been in the thousands...marbel rays falling on you from every angle...just magic!
