The 30 meter vessel shown here is modeled after the traditional Indonesian Pinisi, but with a new purpose... that of being a capable charter yacht.  In my view, the 30m Sailing Pinisi 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.

Kasten Marine Design created the Si Datu Bua design for owner Patti Seery during 2008 as a smaller version of the 36m Pinisi Silolona, also designed by KMD for Patti in 2001.  On Si Datu Bua, we modeled the rig after the 50m Sailing Pinisi, another design we created for Patti in 2007.  The goals with this smaller vessel have been to provide sailing performance in keeping with a traditional sailing yacht, as well as comfort, privacy, and no shortage of onboard luxury.

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...

Alternate Layout

The above layout assumes that the target charter clientele will want the maximum accommodation space and personal service for diving, cultural charters, and to participate in gourmet cooking.  This of course is not everyone's agenda... so we have developed an alternate interior layout that instead maximizes the number of guests, but without crowding...  In order to accomplish that, the lower deck layout could be arranged as follows:

In this case, the lower deck galley is expanded in order to serve the larger complement of guests, and there are six guest cabins below forward.  On deck, an additional VIP suite has been added inside the deck house aft, as follows:

In the above imagewe can see that it would be an advantage to move the engine room air intakes to the aft corners of the lounge, which would open up the forward end of the lounge to allow the table to seat all fourteen guests.  A simple change really. 
 

Sails, Power, Range

The sail rig is relatively "modern" among the Indonesian Pinisi, even though it has quite a traditional appearance. The rig is tall, and carries a generous sail area. The spars are steel tube, which to the casual observer have the same appearance as traditional wooden spars.  Steel however provides the strength needed in order to achieve adequate sail area and is easily fabricated. The sails are modern Dacron, the halyards are soft laid Dacron, the halyard and sheet blocks have wood cheeks and ball bearings for low friction hauling. In general 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. Further acknowledgments for this design can be found at Superyacht Times. For a taste of what is possible with these craft, please see our 36m Dunia Baru web page where you will find a number of outstanding as-built images.

If this or a similar Pinisi / 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.
