The Sea Hunter


The Pioneers of Cocos Island Diving

The Sea Hunter, part of the Undersea Hunter Fleet, is one of the pioneers of liveaboard diving in the Cocos Islands and, hence, is also one of the most sought-after. Booking in advance is definitely required.

The Liveaboard

Part of the Undersea Hunter fleet, this safe and stable vessel, purpose-built for long-range exploratory diving missions, measures 36 metres long and offers an exceptional steel-hulled base for your Cocos Island dive adventure.

Taking divers to the Cocos Islands all year round requires a high degree of safety and professionalism, given the remote nature of where she is heading. The vessel is equipped with a unique stabilizing system to make sure the trip out there is comfortable, and all the facilities you could need are catered for. Of note is the superb dive deck, the fantastic camera room, and oodles of space for relaxing.

Arrival Day:

You must arrive at least one day before the boat departure date.

Upon arrival to San José, there will be transportation waiting for you (please get in touch with us for a quote), or you can take a taxi to your hotel. There are always taxis available at the airport, even minivans for those of you who carry a lot of gear. We can also recommend and arrange accommodations for hotels in San José. Kindly note transfers are not included for all hotels, please contact us for a list.

The evening before boat departure, we will contact you to confirm your pick-up time the next day. The evening is at your leisure. Air transport, airport transfers, hotel nights and meals before and after the cruise are not included in the charter.

Day 1:

The following day, generally between 8 AM and 1 PM, we pick up from certain hotels and transfer everybody by bus to Puntarenas, where you will board the vessel. The drive takes about 2 1/2 hours and gives you a chance to view the lush forest and rich farmland of the region.

Due to occasional low tides,  boats may need to depart from the pier earlier in the day. Should this occur, you will be transferred by skiff to the vessel. When all passengers have arrived on board, the ship will take a 32-36 hour cruise to Cocos Island.

Day 2:

A travel day. There will be time to arrange dive and camera gear as well as enjoy the Pacific and the sunshine. Also, the group of incredibly experienced divers provides plenty of stories to pass the time. There are videos and the experience of the Captain and crew to help you get excited about the diving…as if you need them. In addition, you may want to take this time to take one of our diving courses.

Days 3 – 8:

Spent diving the pinnacles around the perimeter of Cocos Island. Divers usually average three dives daily at depths of 60-100 feet (18-30 meters) or more. This, of course, is what the whole trip is about.

Day 9:

Make the last 3 dives before the cruise back to Costa Rica and reality!

Day 10:

All day to discuss the diving and to compare your adventures!

Day 11:
