S/Y Indo Siren is more than just a Phinisi diving yacht, and it’s more than a luxury boat, too. Everything from its conception to its onboard facilities is perfect for discerning guests who want to enjoy liveaboard diving trips in Indonesia. Purpose-built and new in 2011, the boat was designed by divers, for divers. It has size and modern technology to ensure that the cruises are safe and comfortable in all sea conditions, but it still has lots of classic charm, made from Ironwood and furnished in teak. Divers can enjoy the special feeling that only classic styling can give, but still have creature comforts, and modern luxuries when on board.
Up to 16 lucky guests enjoy cruises of one week to up to a fortnight. The twin and double cabins are independently air conditioned, have en suite bathrooms with hot & cold fresh-water showers and audio/video entertainment. The large cabins have space and storage areas for the guests to truly feel at home throughout the cruise, along with fresh towels, bathrobes, a hairdryer and security box.

Underwater photography is becoming more and more popular, and often more than half of the guests bring cameras and more. Indo Siren has designated outdoor and indoor camera workstations, with charging facilities, personal rinse tanks, and more. In the lounge there are large sofas and armchairs, a large flat-screen television with an extensive movie library and even a cocktail bar. There are complimentary kayaks for guests, and massage & laundry services. The two motorized dinghies are used for diving, and to transfer guests for land and beach excursions.
For divers on S/Y Indo Siren, the competitive rates include free use of diving equipment and free Nitrox. Those who don’t have Nitrox certification can easily take the course on board with one of the professional instructors on every cruise. Open Water divers can also take the Advanced Course.

It total, there are 8 private cabins on this 40m yacht, and the (12) crew & diving staff take the best and most-professional care of the guests throughout the diving cruises. Delicious food is served, that is a wonoderful mixture of local and western cuisine. Also, local beer and soft drinks are for free.

The whole experience is enjoyable, from start to finish, and both above and below the surface. Although the yacht is very luxurious and easy to relax on, there’s plenty of other things to do during the trips, including kayaking, beach excursions and snorkeling in crystal-clear water at healthy, colourful reefs.

Booking / Enquiry

M/Y Indo Siren has three main itineraries. From May to October, the trips are around Komodo, and from November to May at Raja Ampat. This is to always be in 'high season' to enjoy the best weather and diving conditions.

The other itinerary is a 'crossing trip,' which is from Komodo to Raja Ampat or vice versa. These crossing trips explore the less-discovered reefs of the Banda Sea.

Before every dive on M/Y Indo Siren, guests will be given a comprehensive dive briefing. It is both polite and necessary to pay attention, as doing so will greatly improve your experience once underwater.

The itineraries below are the most-common for each trip, but these can sometimes be changed for a number of reasons. Small changes are made due to weather & sea conditions, special marine life sightings, overcrowded dive sites, local-authorities' instructions, and the needs & requests of the paying guests. The safety & comfort of all guests is most important at all times.
