Built for comfort and stability, the Cocos Island Aggressor is a 38 meter/124ft liveaboard that accommodates up to 22 passengers in 11 staterooms – 4 master staterooms on the upper deck and 7 deluxe staterooms on the lower deck. Each room has a private bathroom, shower, and air conditioning, and every passenger gets a spacious locker for their dive gear. The Cocos Island Aggressor has a spacious salon, a large sun deck, loungers and deck chairs, a bar, and a grill. With a varied, mouth-watering menu, lunches consist of lighter meals such as hot soups, salads, and sandwiches. The talented onboard chef prepares delicious dinners that include salads, seafood, beef, or chicken, BBQ, and even fresh homemade desserts. There is a variety of complimentary fruit juices, soft drinks, water, iced tea, coffee, and a limited selection of local beer and wine. All meals, snacks, and drinks are provided.

Boarding and departure times are subject to the tides. Immediately after boarding, the liveaboard departs for its 36-hour crossing to Cocos Island. During trips and between dives, guests can hang out at the bar on the top deck and catch up on the diving of the day while relaxing on the comfortable loungers. The Cocos Island Aggressor offers multiple dives throughout the day for an average of 21 dives on a 10-night trip. No night diving is currently offered at Cocos Island.

Guests can enjoy diving at the Cocos Island National Park UNESCO World Heritage site, for the chance of big fish encounters with creatures like hammerheads, whitetip sharks, manta rays, and whale sharks. Aside from the incredible diving, guests will also be taken ashore to hike through the jungles of Cocos and swim in waterfalls.

Great diving in Coco Islands

An amazing experience diving one of the more remote places in the world. Unfortunately the "new" boat (which seemed refurbished at best) had issues and our bow cabin was very cramped and certainly not as advertised.

Excelente viaje que hizo una experiencia agradable de convivencia con tripulacion, guias y compañeros de viaje. Repetible.

El viaje completo es memorable. Como idea para mejorar, mi cabina era la #6 y presentó problemas fe mal olor, tal vez por algún asunto de drenaje, hay que revisarlo
