Launched in April 2011, the 40m Indo Siren was built on the Indonesian island of Sulawesi and is handcrafted from ironwood and teak (traditional to the area). You will find no other diving liveaboard as beautiful in Indonesian waters, and being built by divers for divers, you can rest assured that every need has been thought of and addressed.
Welcoming a maximum of 16 guests per trip ensures that there is ample space to relax. The 8 cabins are comprised of 2 fixed doubles, 2 flexible twin/doubles and 4 fixed twins, all offering air-conditioning and private en-suite bathrooms with hot water
