Built to almost the same specifications as South Siam 3, the boat can accommodate 28 guests in twin shared air conditioned cabins, and two double bed cabins. The boat has 6 shared bathrooms. A large shaded outdoor area where meals are served, an indoor air con saloon with TV/DVD entertainment center, plus a huge sundeck.
The boat offers almost as much flexibility as her sister ship, guests can join/leave the boat five days per week via speed boat transfer. Unlike her sister ship she also visits dive sites further north including Koh Tachai, great spot for Leopard Sharks and Richelieu Rock which is one of our all time favorite dive sites in the Andaman Sea. Sea Horses, Harlequin Shrimp, Cuttle Fish, Manta Rays, Whale Sharks, you can see just about everything at this top Thailand dive site.
South Siam 4 allows you to visit all the great sites in as little as 3 days and 2 nights which is the shortest duration you can book on this boat. You can stay onboard as long as you like, just make sure you trip includes a Wednesday or a Sunday as these are the days Koh Bon, Koh Tachai and Richelieu Rock are visited. These are also the only days of the week when it is not possible to join or depart the boat. The other advantage of South Siam 4 is that day trippers do not join the boat, so it is less crowded.
South Siam 4 dives around the Similan every day of the week except Wednesdays and Sundays when she goes up to Surin island, Richelieu Rock, Koh Tachai and Koh Bon for the day.
South Siam 4 you can get on and get off the liveaboard boat 5 days a week and you get to go to Surin, Richelieu Rock and Koh Tachai as well as Similan and Koh Bon.
