Vessel information

Sea Hunter liveaboard is owned and operated by Undersea Hunter Group, one of the world's preeminent adventure dive operators. For more than 30 years, the fleet has specialised in liveaboard diving trips to the legendary Cocos Islands, while also offering unique project capabilities almost anywhere else on the planet. Throughout this time, the Undersea Hunter Group have dedicated their vast experience and ever-evolving technology to providing successful, unique and rewarding experiences for adventure divers, filmmakers and scientists alike.

Formerly a commercial dive-support vessel, built to serve the oil industry in the Gulf of Mexico, the 36-metre Sea Hunter is a superbly stable and robust craft. Purchased by the Undersea Hunter Group in 1994, and following eight months of extensive redesign and renovation, Sea Hunter is now one of the paramount purpose-built liveaboard vessels in the region. Combining the large platform, functionality and powerful machinery of a workboat with the comfortable and relaxed interior of a modern yacht, Sea Hunter sets a new gold-standard for all other dive boats.

Onboard Sea Hunter

This 36-metre vessel accommodates up to 20 guests in ten comfortable cabins. The ship’s main saloon offers cosy seating and nightly entertainment including slide shows, DVDs and games. An additional study comes equipped with a library, TV, DVD and a desktop computer for photo and video editing, and also serves as a classroom. Meals are varied, abundant and well-balanced, offering a soulful combination of American and local Costa Rican cuisine. Sea Hunter’s dining room consists of booths specifically arranged to facilitate conversation, creating a highly sociable atmosphere. And, a large sun deck provides the perfect place to relax between dives. Several Cocos Island excursions are also possible, including waterfall visits, trips to the isolated Ranger Station, or an incredible eight-hour trek to the summit of Cocos’ highest peak.

Diving from Sea Hunter

Sea Hunter liveaboard is everything that a serious diver could wish for with well-designed facilities including individual gear storage provided for each diver and easy access to protected areas for the largest of camera housings. You’ll even find a dedicated washer and dryer for guests’ towels and bathing suits. Nitrox fills are free for certified guests, and the Nitrox Speciality course and ScubaPro rental equipment can be provided at an additional cost. Sea Hunter is also fully tech-friendly, offering extensive tri-mix and rebreather support. Diving is done from three tenders which are extremely stable in all conditions. Personal dive gear is kept onboard the skiffs throughout the trip, reducing wear and tear and ensuring guests are always ready to take advantage of a fleeting opportunity.

DeepSee

This vessel was conceived to serve as the ultimate platform for Undersea Hunter Group’s very own deep-sea submarine - designed and developed specifically with the ocean enthusiast and underwater adventurer in mind. DeepSee is capable of carrying a pilot and two passengers to a depth of 450-metres, providing an unparalleled 360-degree field of vision. Production crews can also make use of a deck-mountable workshop equipped with everything you could need, including IMAX compatible facilities.
