The latest addition to the Undersea Hunter fleet is Argo, a 40 metre vessel that has been recently renovated to accommodate sixteen guests in eight spacious and comfortable cabins. Argo is the result of all the knowledge gained from running Undersea Hunter and Sea Hunter and is far more than just a dive liveaboard. The intention was to blend working ship with luxury yacht and this has certainly been achieved.

Argo operates a year round schedule, visiting Cocos Island on ten and twelve day trips. Guests join the boat at Puntarenas in Costa Rica and there is a 32 hour crossing to reach the island. Once there, the diving is amazing and it`s definitely worth the trip!

Dining aboard Argo to Cocos Island Costa Rica

The main accommodation is on the lower deck with three twin bedded and three double bedded cabins. On the upper deck there are two double cabins with queen size beds. All rooms have shelves, drawers and hanging space, a desk and chair, a satellite telephone for international calls, a satellite connection to send and receive e-mails and a flat screen TV with DVD player. The ensuite bathrooms have 110v outlets and all cabins have individual air conditioning.

On the main deck are the dining room and saloon which are spacious and comfortable. Meals are served as a buffet and are plentiful. The large saloon has a flat screen TV, DVD player and a small selection of videos and games. Guests are invited to bring along their favourites. There is a refrigerator that is constantly stocked with soft drinks, ice and beer which are complimentary.

The Diving

The large dive deck is situated aft on the main deck. Divers are allocated a station with ample underseat storage for their dive gear. Close to the kitting up area is a camera storage area and a large work bench with 110v and 220v recharging points. There are personal camera cubby holes for each diver, again with recharging outlets.

Diving takes place from the large fiberglass skiffs on which dive sets remain during the diving, which reduces the wear and tear on equipment. The tanks are filled in place as soon as the skiffs return to the main vessel, which means that they are always ready if a sudden opportunity arises, such as the appearance of a bait ball or a whale sighting. These skiffs are very stable, an important quality in these remote and exposed waters.

A programme of four dives a day is usual, with two dives scheduled for the morning (8am and 11am), a third dive after lunch (2.30pm) and either a last dive in the late afternoon or a night dive (after 6pm). All dives are preceded with a thorough briefing and a Divemaster accompanies each group.

Nitrox fills are free and unlimited aboard Argo and if you are not yet a certified Nitrox diver, you can complete the course during the 36 hour cruise to Cocos. Other PADI courses available are the Deep Diver and Night Diver specialties.

Argo is fully equipped with Nitrox gas blending systems, partial pressure and membrane compressors and offers full rebreather support, including Trimix with helium and a range of bailout and rebreather cylinders. Please ask our sales staff for prices.

Schedule & Itinerary

Argo operates a year round schedule of mainly 10 and 12 day trips from Puntarenas to Cocos Island. On arrival at the port town of Puntrenas in Costa Rica, guests board the Argo and set off for the 32-36 hour crossing to Cocos Island.

On arrival, the mother ship remains in the sheltered anchorages of either Wafer Bay on the north west coast or Chatham Bay in the north east, while the skiffs convey divers quickly to and from the dive sites.

Travel Info

For trips to Cocos Island you will need to fly to San Jose in Costa Rica. There are several flight options connecting via the States or Europe. For travel via the States a generous connection time should be allowed to clear security and customs. We recommend that you spend a night in San Jose either side of your Liveaboard trip – although it may be possible to fly back to the UK on the day you disembark. It is a 2½ hour bus transfer from San Jose to the sea port at Puntarenas where you will board Argo. It then takes approximately 32-36 hours to get to Cocos Island.
