The South Siam IV serves as a mobile liveaboard dive platform stationed in the Similan and Surin national parks to which guests are transferred daily by speedboat, so you can join and leave whenever you want. No other boat offers you quite as much flexibility.
Strictly speaking, South Siam 4I is not a true liveaboard as it does not make a cruise, and new guests can join on a daily basis. However, it is a good option for low budget travellers who are short of time and do not mind a more crowded boat. The 30 metre long boat is built to handle large numbers of divers.
There is a very big shaded area for relaxing and eating meals on the upper deck, a large sundeck with sun loungers and an air-conditioned saloon with TV/DVD and music system. All cabins have sea views and individually controlled air conditioning, they are pleasantly decorated and each bed has it's own reading lamp.
Finally, if you're a snorkeller or non-diver, the trip accommodates you equally as well as the scuba divers, and excursions onto the islands' white sand beaches are provided if you'd like to do some beachcombing.
