South Siam 3
Shortest Richelieu Rock liveaboard

South Siam 3 DM’s
South Siam III is a Richelieu Rock liveaboard that offers divers the flexibility that other boats can’t match. The boat stays out at the islands all season (mid Oct to early May) and divers are transferred from the mainland to the liveaboard five times per week by speedboat.
South Siam 3 is ideal for short liveaboard trips of one or two nights. In 2 days you can dive Similan Islands and Koh Bon. The shortest Richelieu Rock liveaboard is 3 days 2 nights. If you can schedule your diving for Wed-Fri or Sun-Tue you can dive at Richelieu Rock, Koh Bon and Koh Tachai as well as the Similan Islands in just 3 days and 2 nights.
The crew are young and fun. The food on board, served buffet style, is very tasty and there’s lots of it.
Unlike other liveaboards South Siam also takes day trip divers. (Day divers can join at the Similan and Koh Bon but not at Richelieu Rock). This can make the boat busy during the day but the program is efficiently run and the day trippers have all departed by 3 pm.
Peak season holidays like Christmas, New Year and Chinese New year are busiest (you need to book early for these dates). Because of all the comings and goings and the moving between islands there are fewer beach excursions on a South Siam liveaboard than on other boats.
