The 30 meter vessel shown here is modeled after the traditional Indonesian Phinisi.  Originally all phinisi were sailing craft.  This vessel is a re-incarnation of those types, but with a new purpose... that of being a capable charter yacht.  This design, called "Datu Bua" by owner Patti Seery for whom it was designed, is a smaller version of the 36m Phinisi Silolona (which we designed for Patti Seery in 2001), but with a rig that is modeled after the 38m Sailing Phinisi (which we developed in 2009), and the 50m Sailing Phinisi (which we developed in 2007). 

The intent of this design is to carry a rig that is sufficient to provide sailing performance in keeping with a traditional sailing vessel.  Comfort and privacy have been primary goals. In addition to creating a highly traditional vessel for local construction in Indonesia, the emphasis in this case has been on sailing performance and onboard luxury. 

In my view, the 30m Sailing Phinisi shown here represents the "sweet spot" as an intimate Indonesian charter vessel.  Not too big, not too small, and a capable sailing yacht as well.
 

Particulars

 

The Interior Layout

At 30 meters on deck, the design is just large enough to accommodate 4 mid-size luxury suites below forward, plus a 'tour-guide' or 'steward's' cabin forward.  Given the overall size, the interior layout is not at all crowded. For sailing in the tropics excellent ventilation has been given the highest priority. Each cabin has a private head and shower and all accommodation spaces are air conditioned.

To best understand the vessel's interior the following walk-through should clarify whatever is not readily apparent in the layout drawings...
 

Below Decks

Right forward below the main deck is the fore peak, having a chain locker right forward, and aft of that the 'tour-guide' or 'steward's' cabin.  Just aft of that are four mid-size luxury staterooms, each with en-suite head and shower. 

Aft of this array of deluxe suites is the engine room, sized to house the various support systems for luxury chartering, including two main generators, a "pony" generator, dive compressor, large capacity reverse osmosis system for fresh water, central chiller for air conditioning, electrical panels, etc. 

Aft of the Engine Room are the crew galley / mess and crew sleeping cabins.  Accommodations are provided aft and forward for 10 crew.  Below the crew mess is a cool-room for food supplies.  Right aft, below the main deck is a Lazarette for access to the steering rams and autopilot.

The Main Deck

The forward main deck is the main socializing area during the day and at night it is a favorite place to party and to sleep under the stars.

Amidships on the Main Deck is a Lounge for guest dining that is protected from the weather, and which contains the on-board entertainment system including a large flat-screen display.  A stairway leads directly from the Lounge forward and down to the guest suite hallway below.

Aft of the Lounge, and approximately one meter higher up is the Bridge.  From the Bridge, a stairwell leads down to the crew mess / galley and crew sleeping cabins.  This also provides ready access to the engine room.  To starb'd of the stairwell within the Aft House is a small captain's cabin. 

Right aft within the Aft House is a large Guest Galley, open to the aft deck and available for guest participation in the everyday food preparation.

At the aft end of the Main Deck is another exterior social area / lounge - but one that is covered and therefore out of the sun and weather.  In practice, this has proven to be a favorite gathering spot for an informal Barbeque on deck or for staging a dive adventure or fishing or just for general hanging out...

Sails, Power, Range

The sail rig is relatively "modern" among the Indonesian Phinisi, even though it has quite a traditional appearance.  The rig is tall, and carries a generous sail area.  The spars are all steel tube, and with tapers at the ends, they appear to any casual observer to be traditional wooden spars.  Steel provides the strength needed in order to achieve adequate sail area and is quite easily fabricated.  The sails are all modern Dacron, halyards are three strand soft laid Dacron, halyard and sheet blocks have wood cheeks and ball bearings for low friction hauling.  The whole rig is arranged for easy handling. 

Unlike the traditional Bugis schooners which have "standing" gaffs where the loose footed sails are brailed to the mast and gaff, we have instead arranged for the gaffs to be hauled aloft Western style.  In this way, the sails can remain bent onto the spars, and are very easily reefed.  With booms on all primary sails, there is no drama when tacking.  A generous platform is placed at the base of each topmast, allowing easy handling of the tops'ls as well.

With robust galvanized steel standing rigging, this is indeed "modern" by local Indonesian standards - the objective being to have good sailing and easy handling.  For calm spots... the engine is sized for 10 knots under power.  The engine is a 650 hp Yanmar - not the fast turning little motors we see on small sail boats, but rather a heavy duty slow turning industrial-strength marine diesel manufactured in SE Asia for the SE Asian market.

Fuel tankage is approximately 14,000 liters.  Range under power is planned to be between 1,500 and 2,000 NM (depending on vessel speed). Having been designed for sailing as well, range is essentially unlimited. 
 

More Information...

An interesting article on our work with these vessels appeared in the New York Times, called The Traditional Pinisi - And Then Some.

If this or a similar phinisi  / luxury sailing yacht is of interest, we offer a thorough design service.  Our preference is to take advantage of traditional methods to the maximum extent possible, but to bring the construction standard up to a classification society compliant structure.  We can modify these types of vessels to suit a variety of requests to change the size or to modify the layout as needed, and then follow that up with our local knowledge in order to facilitate construction.

For complete information about the design and building process that we recommend please see the following links, or for more information please inquire.
