The Argo is 40 metre boat which blends a work ship with a luxury yacht. Extended, multi task cruises are her speciality and she is the mothership for our remarkable Deep See submersible. She has 9 spacious and well appointed staterooms with flatscreen TV’s. DVD players and individually controlled airconditioning and can accommodate 18 passengers. A comfortable and stylish lounge and dining area offering a combination of American and Costa Rican cuisine and a sun deck which is perfect to catch the sun and enjoy our BBQ’s. Each of our vessels has hard fiber skiffs which are custom built and have space to secure your tank and can fit 10 divers plus dive guide and driver.  Each skiff also has a metal ladder and rooftop. Although this vessel maybe more expensive, its popularity amongst repeat divers as well as professional photographers, professional film crews and conservation organisations ensures you receive a far superior diving experience.  We also offer a submersible experience (at an extra charge) to all our passengers.

 Diving Schedule


 Our goal is to introduce you to varied and exciting dives. Generally, we have two dives scheduled for the morning, 8 AM and 11 AM and another dive after lunch, around 2.30 PM. During the trip it will also be possible to do at least three night dives. This schedule can vary depending on events, circumstances and opportunities that may present themselves. Our motto is never turn your back on a magnificent bait-ball, which can appear at almost anytime. Once a thorough briefing from our dive-masters has been given onboard the mothership, our guests jump onto their respective skiffs and zip out to the chosen sites. Each support boat accommodates up to nine divers plus driver and dive-master, who always dives with the group. After a short ride, each of the skiffs will reach a different dive site that is alternated on the following dive, allowing the two groups to dive the same areas but at different times of the day. On the way to or from the planned dive sites it is very common for our skiff drivers to seek out the best spots for memorable surface experiences. To watch dolphins, mantas, whales, a promising bait-ball or just cruse up to some of the islands most beautiful attractions, which are only reachable by small skiff. Between dives or when time permits, guests are welcome use the sea kayaks, go for a swim, snorkel around the boat, or just chill-out and watch movies. Schedules and Rates
