The Okeanos Agressor is a great choice if you would like a fantastic crew with great diving. The boat is a little tired, and the rooms are quite small, but it is functional, and the crew more than makes up for the rooms. There is a camera table, rise tank, and the dive deck is well organised. Lots of food, perfect for diving. The diving itself was magical, lots of sharks, probably the best night dive in the world and macro. I loved the schedule of the dives, and the flexibility - the dives were tailored to the conditions. I managed to do 5 dives a day on 3 days, and 4 dives the remainder. Great for photography.

I have been on the Okeanos Aggressor 4 times and will be going again next year.

The Rooms are kept very clean, and the Staff are excellent

Food: The good is first class, always fresh, because the owner of the boat, bought a truck just to pick up fresh never frozen local fruit and vegetables before each trip, and Chef Douglas will always make anything you request on short notice.

Staff: The staff has been together for a long time and know the waters better than anyone else, Captain Beto has been diving these waters for over 20 years, and still leads Every dive! They truly treat you like family, not as a customer.

Marine Life: On every dive you will see thousands of fish, and hundreds of sharks of different species, we had orcas on the last trip, plus mantas and tiger sharks. Most people who come for the first time say, each dive is the best dive of their life. This is considered to be the # 1 Big Animal encounter in the world and it lives up to it's billing.

This is a trip for Advanced Divers, due to current and changing conditions.
