South Siam 4 ‘s On-board Facilities
The communal areas on the South Siam 4 are spread over the upper and top decks. First, the upper deck is where you will find a spacious living room area, fitted with a complete audio/video entertainment system. Secondly, at the back of the vessel, you’ll find a spacious covered dining area where everyone can sit comfortably.

Scuba Diving with the South Siam 4
Despite the large number of guest the Somboon 4 can welcome, the dive deck should never feel over crowded as it appears well organized. Indeed, with individual gear stations, boxed storage and hangers for your wet suit, that’s all set!

Furthermore, there’s a very convenient dive platform located at the aft which will allow easy water entries and exits. Finally, the experienced team of dive guides and instructors on-board should be guiding you through an incredible adventure to the best dive sites of Thailand! Needless to remind you of the reputation of Koh Bon, Tachai and especially Richelieu Rock… just head there and dive it!
