She cruises at 10 knots and has a range of 3000 miles.

The dive deck provides gear lockers and storage space for equipment. Dive information is displayed on a large board which shows depth and marine life information. A large three-tiered camera table has plenty of space for camera assembly or preparation and separate rinse tanks are kept for cameras and videos. The photography department provides rental cameras and accessories as well as the services of the photo pro if you require a model or expert advice. A range of PADI and NAUI speciality courses are offered on Okeanos Aggressor including Nitrox training and facilities. A full range of diving equipment is available for rental by pre-arrangement. Diving usually takes place from the two 18-foot inflatable dinghies, apart from night dives which are conducted directly from the boat.

For after the dive there is a shower and clean towels awaiting, as well as the chef’s freshly prepared snacks to appease the after-dive hunger pangs! Delicious barbecues, American-style and local dishes are served; breads, biscuits and baked snacks come strait from the oven. Most meals are served buffet-style.
