General Concept

The privateer concept shown here is intended for construction in Indonesia using top quality tropical hardwoods.  The objective has been to propose a well equipped charter vessel for the Indonesian archipelago and for sailing the oceans of the world.  A fully capable motor-sailor with excellent sailing performance.

As compared with the usual Indonesian Pinisi and KLM types, our 'privateer' designs have less rake to the stem and the overhang aft is modest.  These changes allow the interior layout to be contained in a lesser overall length than would be required in a similarly appointed Pinisi or KLM.  By comparison a typical Pinisi would have to be around 50 to 55 meters length on deck for an equivalent amount of interior accommodation space.

The goal here is to accommodate ten or more charter guests with a complement of fourteen to eighteen crew.   The guest cabins have been located amidships, with crew located aft.  A generously sized lounge is located amidships on deck, and a gourmet galley is located inside the deck house aft.  The layout that we have planned includes five large guest suites below, four of which are equal, plus a larger owner's suite located forward which can function as a V.I.P. suite for charters.   

Particulars are:



The construction methods used in South Sulawesi are plank-on-frame using tropical hardwood.  Frames are sawn futtocks which are scarphed together rather than lying side by side.  By tradition the planks are erected prior to the frames being installed, therefore all planks are edge fastened using a combination of hardwood dowels and galvanized drifts.  Built in tropical hardwood, the displacement is relatively heavier than today's cruising yachts. 

Please see our Pinisi History page for more information about the construction methods used in Indonesia.   For our recommended path to achieve the highest quality, check out our article on Pinisi Building.


A three mast "tern schooner" rig has been chosen for the sake of easy sail handling, ample sail area, and the best performance under sail.   Although it is common for the Indonesian Pinisi sailing rigs to use a standing gaff with the sail brailled to the mast, we have elected in favor of a standard Western gaff so that the sail and the gaff can be raised and lowered together.  This provides much greater flexibility in reefing, less windage, and in general far easier sail handling.

As a result of the vessel's heavy displacement it is able to carry all steel spars, which are no heavier than tropical hardwood.  Steel spars simplify the rig construction and dramatically increase the strength and longevity of the rig. 


EXTERIOR: The exterior configuration can be seen in the images shown here.  Like the other vessels in the 'Privateer' lineage, there is a raised aft deck.  The layout planned for the aft deck includes seating around a large table, with direct access to the galley in the aft end of the deck house.  On the forward deck are seating pods that can be converted into Asian platforms for informal lounging on deck, or for sleeping under the stars.  

INTERIOR ON DECK:  The aft part of the deck house contains the galley, with the bridge in its forward end.  The on-deck location for the galley was chosen in order to allow the guests to participate in gourmet cooking adventures - a central feature for charters.  A walk-in fridge is provided just forward of the galley, along with dedicated cool room below. 

In the deck house right forward of the bridge is the lounge.  Wrap-around seating is to port and a formal dining table is to starb'd.  A media center is located to port and a service counter is to starb'd.  A stairway on center leads down to the guest hallway, providing ready access to the forward guest and V.I.P. cabins.

INTERIOR BELOW:  Four deluxe en-suite guest suites are located below forward, plus one larger V.I.P cabin all the way forward.  The guest suites are accessed via the stairway leading below from within the on-deck lounge., and from a companionway scuttle on the fore deck.  Each guest suite has a king size double bed, a writing desk, couch, coffee table, large wardrobe, and an en-suite head and shower.

Aft of the guest cabins is the engine room and mechanical spaces.  Aft of the engine room are the crew quarters, which contain a separate crew galley, lounge, and cabins for up to eighteen crew.


The 45m Kalimantan Privateer concept shown here is a much larger version of our 20m Sulawesi Privateer and 31m Komodo Privateer designs.  The larger size allows the vessel to have much bigger ultra-luxury guest suites.  Alternately, the accommodations could be re-arranged to carry 12 guests with an additional VIP / Owner's cabin as in our 36m Lombok Privateer

An interesting article on our work with the wooden vessels of Indonesia appeared in the New York Times, called The Traditional Pinisi - And Then Some.  For a taste of what is possible with these craft, please see our Dunia Baru and Amandira web pages where you will find several outstanding as-built images.
