Argo

The only liveaboard offering a unique virtual tour experience.

Argo is a 39 metre boat built for long range expeditions to the Cocos Islands for 10 day itineraries departing from Puntarenas. She is the mother ship of the DeepSee offering a unique virtual tour experience.

Argo is the physical expression of all the knowledge we have gained from operating our vessels over the years, assembled into a singular, dive expedition cruiser.

Argo is a very intentional blend of work ship and luxury yacht. She was totally redesigned and refitted in 2008, to pamper up to 18 discriminating passengers in 9 spacious, well-appointed staterooms. A 130-foot vessel (40 meters) with full global reach, the Argo was also conceived to serve as the ultimate platform for a deep-diving submersible as well as for remote operating vehicle deployment (R.O.V.). She offers heavy lift capabilities, stability and ample deck space for any chore imaginable. Extended, multi-task cruises are her specialty and of course she is mothership to our remarkable DeepSee submersible.

Fourteen well-seasoned crew look after the ship, the projects and the guest’s every need. A comfortable and stylish lounge, dining area and sun deck comprise the social areas. The ambience is completed with original, undersea themed artwork throughout. The well-equipped galley enables the ship's chefs to prepare fresh, international level, four-star cuisine for mealtimes or at the "drop of a hat".

On board accessories consist of all standard diving gear including scuba, Nitrox, rebreather facilities and zero-speed stabilizers. Three, powerful, 24-foot skiffs serve as tender-boats, which perform submersible tracking duties, shepherding of divers to remote sites, ship-to-shore transfers and any other conceivable recreational or support related activities. All our skiffs are powered by fumeless 4-cycle, 115 HP twin-outboard motors that can bring you rapidly to any dive site within an extended, safe radius of the mothership. They are further equipped with VHF radios, depth sounders and portable GPS. A T-Roof and rigid bow cover is also mounted on these vessels for your comfort.

Double & Twin Cabins

The Argo has cabins for 18 guests. The cabins have heads, showers and individual air conditioning controls. There are also drawers, shelves and circular portholes in the cabins.

  • Double bed

Route Options

This beautiful island with its breathtaking marine life, including large pelagics, guarantees an unforgettable trip.

The Cocos Island Marine Park, a world heritage site, is a crown jewel of Costa Rica and was pronounced “the most beautiful island in the world”. Spend a full 6 days diving the pinnacles around the perimeter of the Cocos Island with divers usually averaging three dives per day at depths of 18 to 30 metres. Countless fish, eels, lobsters and many other critters are residents of the hard coral reef and adjacent sand slope of Manuelita Coral Garden while the elusive rosy-lipped batfish can be found at Lobster Rock. The phenomenon of the 'bait ball' can also be observed when little bait fish seek protection by forming a spinning ball.

Arrival Day

You must arrive at least one day prior to the boat departure date. Upon arrival to San José, we can have transportation waiting for you (please contact 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. Please note that we do not pick up from all San Jose hotels.

The evening before boat departure, an Undersea Hunter representative will fax 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 our 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 vessel will take a 32-36-hour cruise out 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 for 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 per day 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

Arrival to Puntarenas. Immediately after breakfast you will be transported back to San Jose. We strongly recommend staying one more night on land, before flying out, in case of any unforeseen delays.

Optional tours

While you are here in Costa Rica it is certainly worth the extra time to visit other aspects of the country that truly make it a natural wonderland. Very active volcanoes, white water rafting, mountain biking, some of the most pristine jungles in the world, coffee plantations, horseback riding, visits to craft centers, and of course, some of the most beautiful beaches in the world are among the activities and destinations available in the country. We would be happy to arrange one day tours or longer trips to more remote areas at the client´s request. Recommended Costa Rican companies will operate these tours.

Submerged Rock

Cocos Island, Costa Rica

Underwater, this rock plunges down both sharply and gradually. It is broken up with large ledges, some with sandy bottoms, and an outer pinnacle. The colourful, prolific fish life gives relief to the harsh contours of the reef. Sometimes the fish gather in such numbers that they momentarily blot out the sun.

Bait Ball

Cocos Island, Costa Rica

This phenomenon occurs when the little bait fish, upon being hunted, seek protection by forming a furiously spinning silvery ball. This is an attempt of a small species to intimidate and confuse a predator. In a bait ball you can find different bait fish and different hunters. Sometimes the bait fish will be trapped between the surface and the hunters below. This is when the boobies and frigate birds will join the feast. These special events can happen anywhere and at anytime.
