Most Liveaboards have fixed schedules, the majority of which offer trips that are four days and four nights in duration. So it is a case of finding a liveaboard that meets your expectations, budget and of course a liveaboard that has dates that match your vacation plans. With South Siam 3 it is possible to join and depart the boat seven days per week and you can stay as long as you want. The way this is managed is the liveaboard stays in the Similans the entire season and guests are transferred to/from the liveaboard via speedboat.

The big advantage of this system is the flexibility, ideal for those with limited time or fixed dates. The downside is the boat stays in the Similan Islands and also offers diving at Koh Bon on Wednesdays and Sundays, which is great location for diving with Manta Rays. But the boat will not visit Koh Tachai or Richelieu Rock.
