Nautilus Explorer Liveaboard
The Nautilus fleet (I've been on both Explorer and Undersea) is top notch. The crew is incredibly friendly and entertaining, they keep their guests safe and the food is amazing. Admittedly some of the rooms can feel a little small but its really not a problem since the only time you're really in them is to sleep and the beds are comfortable. The boat itself is spacious, has plenty of camera space and of course, the crew puts you on the Great Whites. There are no words to accurately describe Great White Sharks. They are incredible, beautiful, powerful and graceful. There is no other feeling like having one of these giant sharks swim by and lock eyes with you as it passes.
