The Okeanos Aggressor I is one of the Aggressor Fleet’s boats that offers dive safaris on Cocos Island.

Boat interior

The Okeanos Aggressor I can accommodate guests in two types of cabins. Deluxe cabins have two bunk-style single 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. These rooms have climate control and private 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.

Dive deck

The Okeanos Aggressor I dive deck is spacious enough for every diver on board to prepare for diving and maintain equipment. It has rinsing tanks and personal storage boxes for gear. There is a big table and several charging points for maintaining cameras.


The Okeanos Aggressor I’s crew takes care of safety during the safari. The boat is equipped with all necessary items, such as first-aid kits, automatic external defibrillators, emergency rafts, and life jackets.

Photographer-friendly boat

The Okeanos Aggressor I 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 on board the Okeanos Aggressor I.


The Okeanos Aggressor I’s itineraries include some of the best dive sites on Cocos Island. This destination only has 20 spots for diving, but there are a variety of diving landscapes and types of dives to experience. Drift dives or blue-water dives are available here. Also, deep pinnacles over 40 m/131 ft deep and vertical walls can be really interesting for advanced divers. Some of the dive sites that are included in Okeanos Aggressor I’s trips, like Dirty Rock and Bajo Alcyone, are truly great opportunities to see hammerhead sharks, 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, and the sea is calmer during this time of the year. The rainy season is the high season for diving on Cocos Island, and is usually the best time to dive with hammerhead sharks.

Take your trip on the Okeanos Aggressor I to have truly unforgettable diving on Cocos Island as well as comfort and an experienced crew.
