The best liveaboard I have ever been on is the Nai’a in Fiji and Fiji is a photogs dream, ton’s of macro and soft corals for color. There are sharks up close in Negali passage and we saw Mantas there too.
The boat it’s self is well run, same crew all of the time, when the crew is off the boat doesn’t sail. Only boat I ever saw with guitar racks in the camera room, the crew all play and sing, be sure to buy their CD for the sound track to his slide show! Meals are chosen from a menu at breakfast, all are sit down not buffet and the best food I have ever had aboard ship.
