Raja Ampat is full of boats with no real knowledge of the dive sites ... only a book with GPS coordinates. The problem ... they can put the boat right on the coordinates and still totally miss the important features of the dive site! I can, unfortunately, vouch for this, having done one trip with a boat that knew what they were doing, and another boat that was clueless about what they were looking for. Even in Dampier Strait, where most of the dive sites are foolproof, we had a guide digging around in the rubble at the base of a slope, when the feature of the site was the fish hanging in the current at the top of the slope. As others have said, choose your boat carefully!
