Koh Bon and Koh Tachai * due to the limitation of Divers from the Similan Park Authorities on each dive site we just know the day before departure around 17:00 which dive sites are available if we are not able to dive Koh Bon or Koh Tachai then it will be a Similan Island dive site.

M/V Blue Marlin, built in 2018, was specially equipped by us for diving trips. Our innovative tank brackets, behind the seats, leave plenty of room to move or stretch your legs. Also innovative is our dive platform which is rather not to be found on speedboats, but allow you an easy entry and exit into the water.

With a maximum of 20 divers and 5 instructors we bring you to the best dive sites of the Andaman Sea.

With the 3 outboard engines with 250 hp, we bring you two times a week, in about 1 hour and 20 minutes to Richelieu Rock, probably the best dive site in Thailand. To the Similans, which we go 1 time a week, it is a little bit longer, since we leave from the Nam Kem pier.
