Somboon 3 and 4

The Somboon 3 and  4 are a lower budget liveaboard and accommodates a maximum 28 guests in twin or double air-conditioned cabins, with 6 shared bathrooms. On the upper deck you find a large shaded outdoor seating area where large meals are served to hungry divers, plus an indoor air-conditioned lounge equipped with TV and DVD. On the very top deck is a large sundeck.

Somboon 3 and 4 are the ideal choice for a lower budget, short trip that includes all the dive sites normally visited by trips of 4 - 5 days. Great if you have a short time but want to see as much as possible. With trips as short as 3 days / 2 nights including the Similans, Koh Bon, Koh Tachai and Richelieu Rock there's a great variety of diving in a short period.

All trips on the Somboon 3 and 4 start very early - pick up time in Phuket is between 6 - 6:30am. Guests are transferred by minibus to the port of Thap Lamu, around 2 hours drive from Karon Beach, and there transfer to the speedboat for a 75 minute dash to the Similan Islands. On your final day you will make 3 dives in Similan, and expect to be back in Phuket by 6 - 7 pm. Transfers from / to Khao Lak are also possible. Note that in peak times the boat is likely to be quite crowded and day trippers can join some days too. You have 28 guests sleeping on the boat, and on changeover days there can sometimes be 40+ divers.
