Andaman Tritan Liveaboard Information

Andaman Tritan is a slightly smaller boat than many of the liveaboards in the area, taking only 16 guests. A very good option if you want something slightly above the low budget, get an en suite cabin and have less divers on the boat. There are 9 cabins in total – 2 Master cabins with double bed, plus an upper bunk and en suite bathroom, 3 Deluxe cabins – 2 with twin bunks and en suite bathroom, 1 with double bed and ensuite bathroom, and 4 Standard bunk cabins with shared bathroom.

The Deluxe and Master cabins are on the main deck, while the Standard cabins are on the upper deck (2) and lower deck (2). The lower deck standard cabins are quite small, but do have the advantage of being single cabins.

The highly experienced boat crew and up to 4 dive crew take great pride in exceptional service whilst always maintaining safety. With 9 cabins, an extensive dive deck, lounge equipped with T.V. & DVD, ice maker, air-conditioned throughout with a full compliment of safety equipment, this vessel is a great deal.
