Emperor Divers Maldives (Emperor liveaboards)

Emperor's southern programme runs December–March: a 7-night Deep South week (Huvadhoo, Fuvahmulah, Addu) and a 14-night Southern Shark Adventure between Malé and Addu that also dives Meemu, Thaa and Laamu. Both are for advanced divers; Emperor recommends around 100 logged dives and warns of strong, unpredictable currents.
