What Makes Our Similan Liveaboard Unique

The Dining

Tom yam Thai soup

What makes a Similan liveaboard such great value is that food and accommodation are included. Food on the MV Blue Dolphin is delicious and plentiful. Our two cooks, Anne and Rat, are probably the kindest people on the boat. They take pride in their work and are more than happy accommodate any food requirements or preferences.

The MV Blue Dolphin features indoor and outdoor eating areas. The excellent food prepared by our experienced chefs will ensure your meals are as good as your dives. Enjoy a light breakfast of cereal, fruit and toast before the first dive. The bigger buffet breakfast will be waiting for you when you return. A buffet lunch is served after dive two, a tasty snack after dive three and a variety of dishes served for dinner after dive four.

The Dive Team

Gohki

Big Blue has been offering the highest standards of diving in Thailand since 1991, and the MV Blue Dolphin Liveaboard only furthers this reputation for quality service. Our multi-lingual staff on board are able to speak English, German, Thai and Japanese. If you have language requirements beyond these, we can accommodate any requests.

All of our staff have years of experience in the Similans and even longer track records for keeping divers safe and happy season after season. Dive groups are a maximum of 4 people (unless larger groups request to dive together). Your gear is washed and your tanks are filled for you by our highly trained staff. The only thing you have to do on board the MV Blue Dolphin is to dive and relax.
