Bracko, also check out the new Aggressor liveaboard to Raja Ampat. They have just started doing those trip after a hiatus of many years and are offering ridiculous discounts for the first few trips in August.
The "new" Raja Ampat Agressor is the Ocean Rover that has joined the Aggressor Fleet franchise. She's not new to the area just new to the Aggressor Fleet marketing model. After the previous owner, Roman, passed away a couple of years ago she was sold to Benthos Liveaboards who operated her on their own but their team were swamped so opted to join Aggressor to handle their marketing for them.
The boat itself is steel hull, strong and reliable. Comfortable but not luxurious. The crew know the area well too, so it is of course a good choice if you can get a good deal on her first trips.
