Terrific coral and macro life in Raja Ampat, also some mantas. Beer on board was affordable. Food was good, better than expected. Staff is very friendly and all seem happy to be working on the boat. Dive layout for the boat is fantastic. Loved the diving, except for the muck dives

Amazing dives, fantastic crew members and dive guides

I had an amazing time diving with mermaid 1. Seeing the mantas was a great experience. The dive guides were very knowledgeable. I was well looked after by the crew members and they were all very friendly and helpful.

The dive experience, coral gardens and ample sea life, for me the highlight was seeing the Mantas.
