Launched in April 2011, the 40m Indo Siren liveaboard 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 be rest assured that every need has been thought of and addressed.
Welcoming a maximum of 16 guests per cruise ensures that there is ample space to relax. The 8 guest cabins consist of 2 fixed doubles, 4 fixed twins and 2 flexible twin/doubles, all with air-conditioning and private ensuite bathrooms with hot water. Each cabin is also equipped with an essential oil diffuser/ humidifier; we use lemon or lavender essential oil in them but, you are welcome to bring your own if you would prefer some other fragrance.
The covered outdoor dining area provides a great setting for your meals and dive briefings. The spacious air-conditioned saloon offers a cocktail bar, comfortable seating, charging station and a large flat screen TV.
The dive deck has personal storage space for masks and other small equipment items, and is likely to be one of the most spacious and comfortable you will have come across. Designated areas for charging and preparation of camera and video equipment, as well as separate rinse tanks, make Indo Siren a top choice for underwater photographers and videographers.
The vessel also benefits from 2 high-powered Zodiacs, kayaks, laundry and massage services.
