She is a former Sulavesi Live-aboard Ocean Rover. The Ocean Rover was built in Phuket and launched in August 2000. She commenced operations in December 2000.

Ocean Rover was purpose designed for comfortable and safe offshore diving. Her thick steel hull is 100 ft/30 m long and 26 ft/8 m wide. She is powered by three Hino V10 420 Hp diesel engines, driving three propellers for extra safety. Her cruising speed is 10 knots and the top speed 12.5, allowing us to visit many far-flung dive sites in one single cruise.

Raja Ampat Aggressor takes a maximum of sixteen passengers in eight cabins which are all located on the main and upper decks. There are NO guest cabins below decks so there are NO loud annoying engine room noises! Six cabins feature large double beds with single upper berths and large panoramic windows. The two forward cabins feature wide upper and lower berths and have dual portholes. All cabins have private en-suite bathrooms, individually controlled AC and lots of storage space.
The huge dive-deck has several camera tables and rinse tanks. Care has been taken to ensure that pho-tographers have safe places to put down their expensive cameras just before and after the dive. RA Aggressor's unique feature is the “Whale-Deck”: The lower section of the dive deck which slopes down to the waterline allowing for optimum ease of diving operations. This “Whale-Deck” is where the zodiacs are stored when the vessel is underway.
