I stayed on Dream Catcher II in Juli 2014 and I had a great experience!
First the diving itself was great. Not easy due to current, but with current there comes big fish. We saw sharks (white tip, reef), eagle rays, manta's, turtles, napoleons. Very cool!
Second on Dream Catcher II. The ship luxurous, comfortable bedrooms and enough places to relax. Food was excellent, great job on such a ship! The whole crew was outstanding and very friendly.
Based on my experience I would recommend Dream Catcher II! Having said that, I am now considering to go back to Maldives early 2015 and will be on Dream Catcher II again.
