Okeanos Aggressor I, Costa Rica

The liveaboard offers excellent diving serviсes, highly experienced crew team. Boat’s quad cabins suit perfectly for traveling with family or company. The yacht features a complete photo center with a computer to download images and a photo table to maintain cameras and a charging station. A trip on board the boat is a great opportunity to discover Cocos Island, Bat Island, and Cano. These destinations are famous for the chance to see big pelagic creatures like bull sharks, mantas, and whale sharks.

Boat interior
The yacht can accommodate guests in two types of cabins. Deluxe cabins have two bunk-style beds, individual showers, and air conditioning, and all have monitors with media players. There are also quad staterooms that you can share with other divers, family, or friends. Each room has climate control and showers. The boat’s lounge area is combined with the dining area. It’s perfect for relaxation after a day of diving and chatting with other passengers of Okeanos Aggressor I. Those who want to stay in the fresh air and enjoy the gorgeous sea view can spend time on the sun deck.

The dive deck is equipped with rinsing tanks and personal storage boxes. There are a table and several charging points for maintaining cameras. The boat has a nitrox membrane.

Safety
Liveaboard's crew takes care of safety during the safari. The boat is supplied with all necessary items, such as first-aid kits, automatic external defibrillators, emergency rafts, and life jackets.

Photographer-friendly boat
The boat is perfectly suited for photographers. The boat’s dive deck has a camera table for maintaining camera equipment, and there are several charging points. It is possible to work with images on the boat’s computer. Photo packages can be rented.

Itineraries
Itineraries include some amazing dive sites on Cocos Island. This destination only has 20 spots, but there are an array of landscapes. Deep pinnacles over 40 m/131 ft deep and vertical walls can be really interesting for advanced divers. Drift dives or blue-water dives are possible here. Some of the dive sites that are included in Okeanos Aggressor I’s trips, like Dirty Rock and Bajo Alcyone, are great opportunities to see hammerheads, which is the main attraction of this area.

When to go
Cocos Island is located on the equator, so there are two seasons for diving here. The dry season lasts from December to May when the sea is calmer. The rainy season is the high season for diving on Cocos Island and is usually the best time to dive with hammerhead sharks

Okeanos Aggressor I Reviews

4.5
Great option for Cocos!
I traveled on the Okeanos Aggressor I in March 2022 and had an amazing trip to Cocos Island. Everything was excellent, the crew went above and beyond to provide and excellent service and ensure our safety at all times, I would definitely recommend this live aboard to other divers. The only thing to note is that the boat is quite old so the cabins are quite small, specially the bathrooms with the shower on top of the toilet.

Cocos Okeanos 1 4-14/12/21
Me and my girlfriend booked this trip short term. Everything went really smooth..(but some people had problems with the mandatory PCR-test). From the first moment we felt super comfortable and welcomed by all the crew and guests. During crossing we were well looked after. From dive 1 up to dive 21 we enjoyed the dive sites and were really nicely briefed and prepared for all the dives. The guides gave us the freedom we need while still being able to show us things and keep up the safety standarts needed. I can highly recommend the Okeanos Aggressor I and its team. PS: the food haha what to say... awesome!!!
