Cocos Aggressor, in detail

Cocos Aggressor

The Cocos Island Aggressor offers a blend of comfort and adventure for diving enthusiasts. This 38-meter (124-foot) liveaboard accommodates up to 22 guests in 11 well-equipped staterooms, including 4 master rooms on the upper deck and 7 deluxe rooms on the lower deck. Each stateroom features a private bathroom, shower, air conditioning, and a spacious locker for dive gear. Onboard, guests can relax in a spacious salon, enjoy the sun deck with loungers and deck chairs, or visit the bar and grill.

The dining experience onboard is a highlight, with an extensive menu prepared by a skilled chef. Lighter lunches include soups, salads, and sandwiches, while dinners range from fresh seafood and barbecued meats to homemade desserts. Guests can enjoy complimentary beverages, including fruit juices, soft drinks, water, iced tea, coffee, and a selection of local beer and wine. All meals and drinks are included in the trip.

Departures are dependent on the tides, and after boarding, the vessel embarks on a 36-hour journey to Cocos Island. Throughout the 10-night trip, guests can relax between dives on the top deck or socialize at the bar. Divers have the opportunity to enjoy up to 21 dives, though no night dives are currently available at Cocos Island.

As part of the adventure, guests will explore the Cocos Island National Park, a UNESCO World Heritage site known for its abundant marine life. Highlights include sightings of hammerhead sharks, whitetip sharks, manta rays, and whale sharks. Beyond the dives, there’s the chance to venture ashore for jungle hikes and swim in the island’s waterfalls.
