MV Undersea Hunter dive boat review

Undersea Hunter Fleet are one of the premier dives safari operators visiting the amazing Cocos Islands. MV Undersea Hunter is the eponymous mother vessel fo the fleet and the sister vessel of MV Sea Hunter and MV Argo.


Sometimes known as the ‘Golden Triangle’, the Cocos Islands are 550km off the coast of central America’s Costa Rica. Largely unaffected by human interaction for millions of years, the Cocos are an impressive uprising of volcanic rocks and plateaus. Cocos were declared a marine park in 1978. And, today, remain 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. In the right season whales uitlise the Cocos Islands to shelter, congregate and give birth. Cocos also features in excess of 25 endemic fish species, including such special species as the red-lipped batfish. Cocos Islands are a diver’s dream.



MV Undersea Hunter is 90ft long making her the smallest of the fleet. The company’s ‘special projects’ vessel, she was originally built in 1968 and put into service for Perry Oceanography in the Caribbean. When acquired, Undersea Hunter spent 5 months being adapted from bow to stern to be an impressive liveaboard option with the modern conveniences expected by today’s diver. She has twin Caterpillar motors and is capable of cruising safely at 9 knots. And, with with hull stabilisers, she is perfectly evolved for the task in hand. She has the full gamut of safety equipment in accordance with International Maritime Bureau (IMB) requirements.
