Under Sea Hunter

Costa Rica Liveaboard Cocos IslandAt 90 feet in length, Undersea Hunter is the smallest of the fleet, a classic boat offering intimacy and charm. As a special projects vessel, she is particularly suited for film or research projects and hosting individual or small group charters. Boasting a larger working deck than her bigger sisters due to smaller interior common areas, her seven guest cabins accommodating up to 14 passengers offer equal or even superior space to those of the larger vessel, Sea Hunter.

Undersea Hunter has completed hundreds of research and photographic missions and has a blue water capacity to last for up to 24 days.
