The Most flexible liveaboards in the Similan Islands

The sister boats Somboon 3 & 4 are the most flexible boats we have to offer. They both run scheduled 3 Day/ 2 Night trips to Richelieu Rock. In between they stay around the Similan Islands National Park. Neither boat comes back to port until the end of the season and transfers are made via speedboat from Khao lak. This allows divers to stay for just 1 Night/2 Days if you’re on a tight schedule or even just a two dive day trip.

Both boats are large and well maintained. They can have a large number of divers for the middle two dives of the day especially in the peak holiday periods around Xmas and New Year. The late afternoon and early morning dives are much less crowded. Only overnight guests (max 28) can join these dives.

The eating area is huge to allow for the extra day trip guests and there is a small air-conditioned saloon on both boats. None of the cabins are en-suite but all have individually controlled air-conditioning and sea views.

If you’re on a limited budget and a tight schedule, then Somboon 4 could be a great option for you.

double cabins available for advance booking

simple tips to reduce scuba diving air consumption

Scuba Diving For Beginners

Improving My Scuba Diving Air Consumption

Let's first start by saying that it's not a competition. Having good scuba air consumption doesn't necessarily make you a better diver. If you're ending the dive 20 or 30 bar behind your buddy but still reaching your planned bottom time then it's nothing to worry about and could simply be physiological differences that are extremely difficult to overcome. Having said that we do have numerous instructors around Phuket that can only be describe [...]

Seahorses In Phuket

We're very lucky to get at least four different species of seahorse in Phuket. They're not hanging off every branch of coral so our guides have to work hard to find them but find them we do. Some of our Phuket diving trips are seem more attractive to seahorses than others. Anemone Reef, Shark Point and Koh Doc Mai are very productive but for some reason King Cruiser isn't. For the biggest variety of species you can try Kata Beach. Ne [...]
