General Concept

The 17 meter Flores Privateer is a classic privateer-style schooner intended for construction in Indonesia - specifically in South Sulawesi near Bira Beach.  The design resulted from a request to create a vessel that could accommodate a couple and two informal guests plus four crew for cruising and diving around the Indonesian archipelago.  The goal here is to provide the amenities of a capable motor-sailer, while also having top performance as a pure sailing vessel.

Particulars are:

The construction methods used in South Sulawesi are plank-on-frame using tropical hardwood.  Frames are grown sawn futtocks which are scarphed together.  Since by tradition the planks are erected prior to the frames being installed, all planks are edge fastened using a combination of hardwood dowels and galvanized drifts, resulting in a very robust and stable structure.

The Rig

The rig is a traditional stays'l schooner / brigantine with gaff main, main stays'l, fore stays'l, and a jib and a flying jib set from the bowsprit.  Light weather sails include a main gaff tops'l, a large fisherman tops'l between the masts, and two square foretops'ls. An optional square course can be set in light weather below the foretops'ls.  This kind of rig is able to provide plenty of sail area for fast passage making without becoming too tall.  In particular the square sails perform exceptionally well off the wind during long passages.   

Although it is common among the Indonesian Pinisi to use a standing gaff with the sail brailled to the mast, we have elected instead to use a standard Western gaff arrangement with the sail and the gaff raised and lowered together using throat and peak halyards.  This provides much greater flexibility in reefing the mainsail, less windage with the sail lowered, and in general allows for far easier sail handling.  The sail plan is actually identical to the Sulawesi Privateer, only reduced in size in this case to fit on the smaller Flores Privateer...

The spars can be built of light weight wood, but we have specified using all welded aluminum pipe and fittings, which vastly simplifies the rig construction, and increases the strength and longevity of the rig dramatically. 

The Accommodations

EXTERIOR:  There is a raised poop-deck aft.  A recessed cockpit is surrounded by cushions and a high bulwark.  A folding table is on center, mounted onto the binnacle.  The cockpit area is protected by a hard Bimini top to provide shade and the enjoyment of open-air sailing.    

On the 'midship deck are two scuttles providing access to the accommodations below.  A seating pod on the foredeck provides open air dining, but also folds down to become an Asian lounge platform for outdoor sleeping.  The seating pod has vent / skylights outboard, located above the saloon below.

The foredeck is raised up to provide headroom for the crew cabin below and provides ample storage for a second inflatable shore boat.

FIRST INTERIOR:  At 56 feet on deck length, this is about the smallest vessel that can be built with flush decks without resorting to cabin trunks. Although the decks are flush, there is 6' - 6" headroom throughout.  The interior layout includes space for two owners aft; two informal guests in pilot berths amidships; and four crew forward. 

The forepeak is dedicated to anchor chain stowage, mooring lines and other anchoring gear.  Access to the forepeak is from on deck.  Aft of the forepeak is the crew cabin which contains four berths.  The upper two berths are semi-enclosed for added privacy.  Right aft of the crew cabin is the crew head to port with a crew shower opposite.  Aft of the crew head is the galley which occupies both port and starb'd sides.  Access to the 'midships deck is provided by a ladder leading upward from the galley.

Aft of the galley is a spacious saloon / dining area with a folding table on center.  There are settee berths port and starb'd, with ample pilot berths above and outboard of the settees.   At the aft end of the saloon is a WT door leading into the Engine Room.  Aft of the engine room is an owner's "great cabin" having a large "island berth" on center.  With cabinets outboard, large wardrobe lockers, and an en-suite head with shower opposite the owner's suite is lacking nothing.  A hallway is provided forward of the owner's "great cabin" for access to the engine room without intruding on the owner's cabin.  In the hallway to port is a door leading into the engine room. To starb'd a ladder leads up to the 'midships deck.

FIRST INTERIOR ALTERNATE:  In the drawing shown below there is an alternate layout for the galley and crew / guest head and shower.  In this case, the galley is entirely to port and is larger.  The head / shower is one compartment, located to starb'd.  This provides a self-contained and potentially more useable galley, as well as much better access to the head compartment and shower for any guests who may be onboard, even if only for a day trip...

SECOND INTERIOR PLAN:  In the drawing shown below, the layout is completely different, having the master suite amidships.  The 'saloon' is aft in an often preferred 'Great Cabin' having a panoramic view and full participation in the galley.  In the 'saloon' the center table is able to flip forward and down to become a coffee table for socializing when desired.    In this arrangement, all sleeping cabins are forward and share a common head and shower room, with the notion that those accommodated forward are one's guests or children.

SECOND INTERIOR PROFILE:  Shown below is the interior profile that matches the Second Interior Plan.  This second layout is close to that of the Mermaid 61

Differences versus the Mermaid are that the engine room has been moved forward, allowing much more room in the aft Great Cabin, and greater width for the Galley and Day Head.  With the galley located aft, there is excellent access to the Pantry / Cool Room to port of the Engine Room.

The cargo hold present in the Mermaid has been eliminated in favor of a more 'Guest-friendly' layout forward, with a large head and roomy shower compartment opposite.  One significant difference versus the Mermaid 61 is that there is no access to the engine room from the owner's cabin amidships.  This provides for a robust, uninterrupted, sound-proofed bulkhead, removes all traffic from the master suite, and allows for a pair of writing desks to be placed athwart the center double berth - all to the good in my view.

The 'Privateer' series originated with our Mermaid 61 design, an all steel brigantine styled after the 1700's privateers, drawing inspiration from the American Brig Swift of 1778.   By comparison, the 20m Sulawesi Privateer was made slightly larger than the Mermaid, primarily for the sake of allowing a pair of guest cabins amidships.   Here we have the Flores Privateer at 56 feet / 17 meters length on deck - a much more compact vessel for use as a personal yacht. 

An all tropical hardwood structure will assure longevity, and the design is specifically planned for easy adaptation to the wooden boatbuilding methods in use in South Sulawesi, Indonesia.  For that purpose, the keel and stem timbers are straight, and the hull form will be easily planked.

As an extension of this design series, we have developed a larger concept design which I have called the 31 meter Komodo Privateer.  The objective with that design has been to accommodate twelve guests within six expanded luxury suites, and to keep the overall size limited to just over 30 meters - primarily for the sake of economy, but without having to squeeze the guests...

I have also developed preliminary concept for the design of a 42 meter version which we call the 45 meter Kalimantan Privateer.  This size allows the vessel to have five much larger ultra luxury guest suites, or alternately to accommodate sixteen to twenty guests for dive adventures.  By comparison, a standard Pinisi hull with sharply raked stem and stern and all of the crew cabins located aft would have to be approximately 15% larger in order to achieve the same charter guest capacity. 

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 web page where you will find several outstanding as-built photographs.

Please see the following links to review our on-going involvement with these craft.  Please feel free to contact me with questions about building a wood boat like this in such an exotic location, and how we can assist during the design and construction process.
