MV Sea Hunter dive boat review

Undersea Hunter fleet bought MV Sea Hunter in 1994 and her operators boast that she now is the barometer vessel in the waters of the Cocos Islands; the standard by which all others are measured. She certainly is a very impressive vessel.


Cocos is found in the ‘Golden Triangle’ 550km off the coast of central America’s Costa Rica. A large uprising of volcanic rocks and plateaus, the Cocos Islands have remained largely untouched in millions of years. They were declared a marine park in 1978 and are home to some of the most impressive pelagic life on the planet. This is one of the last places on earth where you can still see large groups of sharks and rays in their natural environment and is on the bucket list of every experienced diver.



MV Sea Hunter is 115ft/35m long and has been specifically renovated and reconfigured to be one of the ultimate hybrid dive vessels. Formally a commercial dive vessel she has now been breathtakingly adapted to be a superb liveaboard option with the modern conveniences of a luxury yacht. With 1200hp on tap and capable of powering through the waves at 10knots, Sea Hunter is solid and stable – the ideal vessel for long offshore expeditions.

Sun Deck


Moving to the upper deck there is a huge area which can be used as a sundeck to soak up the rays. Or, sometimes, is used a the BBQ area as you watch the sun set over the Pacific Ocean.



Diving onboard Sea Hunter


The diving at the Cocos Islands is challenging and not for beginner divers or those uncomfortable with computer and DSMB use. There are sometimes string currents and waves at the more challenging sites. However, for those that are suitably experienced, the rewards are immense.


The diving facilities are superb. For the happy snappers there are 20 individual camera/gear locker spaces and a camera bench.

Dive Deck


The dive deck itself is spacious and well segregated providing you with plenty of room to put on and take off your equipment.


The trip requires certification to minimum of 40m and use of Nitrox is highly recommended. Should you wish to train to use Nitrox, training onboard is available. Dive computers are mandatory.





The itineraries generally take the vessel to Cocos (and sometimes Malpelo) 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. Expect to pay around EUR5,061 for this length trip. This equates to EUR460/day making Sea Hunter not inexpensive. However the diving is world class. Please note that this does not include some extras such as port/marine park fees and equipment rental. Please contact us for further details.
