Phinisi interior fit-out cost is the budget line that surprises almost every first-time commissioner — and the reason is structural, not accidental. When owner Mark Robba contracted Konjo builders in Sulawesi to build the 51-metre Dunia Baru, the hull and superstructure were quoted at USD 130,000 [VERIFIED — Boat International, owner-stated]. On a finished charter-grade vessel, that wooden hull often represents less than ten to fifteen percent of total project spend. The other eighty-five to ninety percent is machinery, systems, and interior — and most of it happens not on the beach at Tana Beru but at a fit-out yard hundreds of nautical miles away.
This piece breaks down where that money goes, why the geography of fit-out matters, and what the honest cost brackets look like at each stage. Every figure below is flagged by confidence level. The only verified anchor numbers come from the public record; the rest are observed market ranges that should inform your planning, not your contract.
What “Fit-Out” Actually Covers on a Phinisi
Builders in Bulukumba deliver a launched hull — timber, frames, planking, basic deck, sometimes a superstructure shell. Everything that makes a vessel liveable, safe, and commercially operable is separate. The fit-out scope on a charter phinisi typically includes:
- Interior joinery and cabinetry
- Cabin furniture, wall panels, ceiling liners, berth platforms, storage lockers, saloon seating, wheelhouse joinery. On a mid-range 30–35 metre vessel this is typically eight to fourteen cabins plus saloon, wheelhouse, and crew quarters. Custom teak joinery at charter quality runs USD 80,000–250,000 for this scale [ESTIMATE — no published benchmark exists for phinisi joinery specifically; derived from comparable Southeast Asian wooden vessel refits].
- Ensuite plumbing and heads
- Marine toilets (manual or electric, holding tank fed), washbasins, shower trays with drainage, hot-water systems, grey water and black water tanks, overboard discharge compliance. Each fully fitted ensuite on a charter vessel runs roughly USD 3,000–12,000 in materials alone [ESTIMATE], depending on fixture grade. Plumbing labour in Bali or Surabaya for a ten-cabin vessel adds USD 15,000–40,000. Holding tanks and a proper sewage treatment or retention system — now expected by Western charter brokers — add USD 8,000–25,000.
- Air conditioning
- Reverse-cycle marine AC units per cabin plus saloon and wheelhouse. For a charter-grade 30–35 metre vessel, expect eight to fourteen cabin units plus common areas. Marine-grade units for tropical duty: USD 800–2,500 per unit [ESTIMATE], not including installation, ducting, and the additional generator capacity they demand. Full AC installation for a mid-range vessel typically lands USD 30,000–80,000 all-in [ESTIMATE].
- Electrical systems
- This is routinely where build cost surprises compound. The 12/24V DC system, 240V AC distribution, switchboard, circuit protection, wiring runs, shore power inlet, battery banks, solar if specified. A competent marine electrical installation for a 30–35m vessel runs USD 25,000–70,000 in materials; labour in a Bali or Batam yard adds substantially. Inadequate electrical systems are the leading cause of fire on Indonesian liveaboards — a fact the insurance market now prices explicitly.
- Galley and provisions systems
- Commercial-grade marine galley: stainless steel work surfaces, LPG or induction cooking, refrigeration and freezers (typically two to three units on a dive liveaboard, all requiring DC or AC power), dishwashers on higher-tier vessels, pantry and dry store fitout. A properly specified galley for a ten-cabin charter vessel: USD 20,000–60,000 [ESTIMATE] depending on appliance grade and joinery quality.
- AV and communications
- Entertainment systems (individual cabin screens, saloon projector or display, audio), navigation electronics (chartplotter, radar, VHF, AIS), satellite communications — Starlink is now standard on better vessels, at USD 500–2,500 hardware cost per installation plus monthly subscription, or VSAT for higher-tier deployments at USD 8,000–20,000+ hardware. Full AV and comms package for a charter vessel: USD 15,000–50,000+ [ESTIMATE].
- Safety equipment
- Life rafts sized for passenger + crew complement (USD 2,000–8,000 per raft; a ten-cabin vessel needs multiple), EPIRBs and SARTs, fire detection and suppression systems (automatic halon or CO₂ in engine room, heat/smoke detectors throughout), life jackets for all aboard, man-overboard equipment, flare sets, firefighting equipment at each station. Properly outfitting a commercial phinisi for BKI class and Indonesian safety certificate requirements: USD 15,000–45,000 [ESTIMATE] in equipment alone, before installation labour and survey costs.
Add these categories together and one builder’s own published claim becomes easy to believe: Riara Marine — a Tana Beru yard — states that interior fit-out alone “can match or exceed the basic hull price” [builder-claimed, single-source]. That is consistent with the Dunia Baru pattern and with what experienced project managers report from vessels in the USD 400,000–2,000,000 total build range.
Fit-Out Cost by Vessel Tier
The table below presents fit-out cost estimates — covering everything after the hull leaves the builder’s beach — broken out by vessel tier. These figures are market-observation estimates only [ESTIMATE throughout]. No audited fit-out invoices for phinisi vessels have been published. Use these as planning orientation, not as contract baselines.
| Vessel tier | Length | Hull cost estimate | Fit-out estimate | Total project estimate | Hull as % of total |
|---|---|---|---|---|---|
| Budget open-trip | 20–28 m | USD 30–70k [ESTIMATE] | USD 80–280k [ESTIMATE] | USD 120–350k | ~20–25% |
| Charter-grade mid | 30–35 m | USD 80–150k [ESTIMATE] | USD 300–700k [ESTIMATE] | USD 400–900k | ~15–20% |
| Western standard | 35–40 m | USD 120–200k [ESTIMATE] | USD 800k–1.8M [ESTIMATE] | USD 1–2M+ | ~10–12% |
| Superyacht-style | 40–50 m | USD 150–250k [ESTIMATE] | USD 2.5–6.5M [ESTIMATE] | USD 3–7M | ~5–8% |
| Flagship class | 55–65 m | USD 180–300k [ESTIMATE] | USD 6–15M+ [ESTIMATE] | USD 6–15M+ | <5% |
The pattern is consistent: as specification rises, the hull shrinks as a share of total cost. Dunia Baru’s USD 130,000 hull [VERIFIED] on a total project that reached an estimated six times the original USD 1 million projection illustrates the extreme end of this compression. Even at the modest charter-grade tier, the fit-out typically runs three to five times the hull contract.
Where the Fit-Out Happens — and Why It Matters
Standard practice, documented across multiple sources, is to build the hull at Tana Beru, Ara, or Bira in Bulukumba (South Sulawesi) and then tow the launched shell to a separate yard for all systems and interior work [VERIFIED — multi-source pattern]. The tow itself — typically 1,000 to 1,500 nautical miles to Bali (Serangan or Benoa), Surabaya, or Jakarta — costs several thousand to tens of thousands of dollars in fuel, tug hire, and insurance [ESTIMATE].
The choice of fit-out venue is not purely logistical. Michael Kasten, the naval architect behind Silolona, Dunia Baru, and Amandira, identified Batam as a preferred venue specifically because of its duty-free logistics advantages for imported equipment — Batam sits adjacent to Singapore, simplifying the import of European or American marine systems without the duty exposure that applies elsewhere in Indonesia. Surabaya has a deeper pool of experienced marine tradespeople for systems work. Bali (Benoa) is convenient for owners based there and has good access to interior craftsmen, particularly for joinery.
The Lamima exception is instructive. The 65-metre Lamima — widely cited as the world’s largest traditionally built wooden sailing yacht — had her hull built at Ara/Bira using traditional Sulawesi craftsmanship, then was towed not to an Indonesian fit-out yard but to Italthai’s facility in Thailand. That decision reflects the reality at flagship specification: when you need a fit-out standard comparable to a European superyacht yard, Indonesia’s available infrastructure has limits. Thailand’s Phuket and Gulf boatbuilding sectors have invested in the workshop infrastructure, skilled trades, and quality control systems that the upper end of phinisi fit-out requires. The cost premium is real; so is the quality ceiling difference.
For most charter-grade commissions the Thailand route is not economically justified. But for owners targeting USD 10,000+/night charter rates and international broker distribution, the Lamima model is worth understanding.
The FX Problem Nobody Budgets For
Almost everything in the fit-out is priced in USD or EUR: marine diesel engines, generator sets, air conditioning units, navigation electronics, Starlink hardware, refrigeration compressors, life rafts, EPIRBs, upholstery fabrics from established suppliers. The hull contract is typically in IDR, and Sulawesi labour rates are not sensitive to USD movements. But the fit-out budget is exposed to the IDR/USD exchange rate in the opposite direction — if the rupiah weakens during your fit-out phase (it has moved 15–20% over multi-year periods), your hard-currency equipment costs in IDR terms rise by exactly that amount.
This exposure is not theoretical. A USD 500,000 fit-out budget structured in IDR at the time of initial planning can become a USD 575,000–600,000 bill by the time you are purchasing engines and electronics eighteen months later, with no change in specification. Most fit-out contractors price in IDR; most marine equipment suppliers price in USD. The gap between those two pricing realities is the owner’s problem.

What the Fit-Out Phase Reveals About Hull Quality
There is a reason experienced project managers insist on a structural inspection before fit-out begins. The Sulawesi hull-building tradition is genuinely skilled — punggawa (master builders, technically panrita lopi in Konjo) work without blueprints, shaping scantlings from memory and accumulated family knowledge across generations. The results are often structurally impressive. They are not always predictable.
Common discoveries at the start of fit-out: hull frames that do not align with the planned cabin layout, requiring structural modifications before joinery can proceed; deck camber or hatch placement that conflicts with the intended AC ducting run; timber of variable moisture content that causes joinery to move after installation; fastenings of mixed or substandard metal that are fine for a traditional cargo vessel but corrode rapidly in a fully enclosed, air-conditioned interior. Dunia Baru’s USD 100,000 fastener surprise [VERIFIED — Boat International] happened at the hull stage, not fit-out — but the same principle applies throughout. What is not in the original scope will cost money later.
The practical mitigation is pre-fit-out survey by an independent marine surveyor with wooden vessel experience, before you commit fit-out contractors to a fixed price. That survey costs USD 3,000–8,000 [ESTIMATE] and routinely saves multiples of that in rework avoidance.
A Worked Line-Item View: 32-Metre Charter-Grade Vessel
To make the brackets concrete, here is an illustrative breakdown for a hypothetical 32-metre, eight-cabin charter phinisi targeted at the mid-range liveaboard market — fitting out in Bali. All figures are estimates only [ESTIMATE]. Treat them as order-of-magnitude orientation.
| Fit-out item | Estimated cost (USD) | Notes |
|---|---|---|
| Hull tow Sulawesi → Bali | 5,000 – 15,000 | Tug hire + fuel + transit crew; weather-dependent |
| Main engines (2× marine diesel) | 50,000 – 100,000 | ~300–500 hp each; not incl. installation |
| Generator sets (2× marine genset) | 20,000 – 45,000 | Primary + standby; 20–40 kW each typical |
| Fuel system (tanks, lines, day tank) | 8,000 – 18,000 | Stainless or epoxy-lined tanks; fire-code compliance |
| Engine installation + commissioning | 15,000 – 30,000 | Shaft, coupling, exhaust, mounts, sea trial |
| Electrical system (full DC/AC) | 25,000 – 60,000 | Switchboard, wiring, battery banks, solar option |
| Plumbing (fresh, grey, black water) | 20,000 – 45,000 | 8 ensuites + galley + crew; holding tank, water maker |
| Air conditioning (8 cabins + saloon) | 30,000 – 65,000 | Marine units, ducting, additional gen capacity factored in |
| Interior joinery and cabinetry | 80,000 – 180,000 | 8 cabins, saloon, wheelhouse; teak or hardwood finish |
| Galley fit-out | 18,000 – 40,000 | Commercial appliances, refrigeration, surfaces |
| Navigation and communications | 15,000 – 35,000 | Chartplotter, radar, VHF, AIS, Starlink or VSAT |
| Safety equipment | 15,000 – 35,000 | Life rafts, EPIRBs, fire systems, life jackets |
| Soft goods (bedding, upholstery, fabric) | 15,000 – 35,000 | Significant variance by material spec |
| BKI survey fees and certification | 8,000 – 20,000 | Hull survey, stability, safety cert; annual fees separate |
| Project management (12–18 months) | 20,000 – 60,000 | On-site PM; often skipped, always regretted |
| Contingency (20–30%) | 70,000 – 160,000 | Rework, FX movement, specification changes |
| Total fit-out estimate | USD 364,000 – 943,000 | Broad range reflects specification choices |
A hull for this vessel size might cost USD 90,000–140,000 at a Sulawesi yard [ESTIMATE]. The fit-out total above is three to seven times that. The fit-out cost equalling or exceeding the hull price is not the extreme scenario — it is the baseline.

Frequently Asked Questions
How much does phinisi interior fit-out cost in total?
For a charter-grade 30–35 metre vessel, interior fit-out and systems — everything after the hull is launched in Sulawesi — typically runs USD 300,000–700,000 [ESTIMATE]. At 35–40 metres to Western standard, the fit-out alone commonly reaches USD 800,000–1,800,000 [ESTIMATE]. One builder (Riara Marine) states that fit-out “can match or exceed the basic hull price” [builder-claimed]. The Dunia Baru build history confirms the principle: a USD 130,000 hull [VERIFIED] on a vessel where total project cost reached an estimated six times the original USD 1 million projection.
What is the most expensive part of fitting out a phinisi?
On a charter-grade vessel, interior joinery and machinery tend to compete for the largest single line item. Joinery (cabins, saloon, wheelhouse) on a ten-cabin vessel runs USD 80,000–250,000 [ESTIMATE] depending on specification. The machinery package — two main engines, two generators, installation, fuel systems — commonly runs USD 90,000–200,000 [ESTIMATE]. Electrical systems, air conditioning, and plumbing each add further significant cost. At superyacht specification levels, interior joinery and soft goods dominate.
Is it cheaper to fit out a phinisi in Bali, Surabaya, or Batam?
Labour rates for marine trades vary meaningfully across these venues. Batam has a duty-logistics advantage for imported equipment given its proximity to Singapore — a point naval architect Michael Kasten has flagged specifically. Surabaya has a deep pool of experienced marine tradespeople. Bali (Benoa/Serangan) offers convenience for owner-managers based there and good access to interior craftspeople, particularly for joinery. There is no single cheapest answer: the optimal venue depends on your systems specification, your intended classification standard, and where your project manager is based. The Lamima exception — fit-out in Thailand for flagship vessels — is the relevant benchmark at the top of the spec range.
What is not included in a Sulawesi builder’s hull quote?
Standard Sulawesi hull contracts cover timber, labour, hull planking, basic deck structure, and sometimes a superstructure shell. They typically exclude — and this is not exhaustive — main engines and gearboxes, generator sets, all fuel systems, full electrical installation, plumbing, air conditioning, interior joinery, galley equipment, navigation electronics, safety equipment, rigging, sails, the tow to the fit-out yard, certification survey fees, and project management. Dunia Baru’s hull quote excluded USD 100,000 of bolts and fasteners [VERIFIED]. Builders do not quote what they do not supply; owners who do not know to ask for every line item routinely discover large costs outside the contract scope at the point when they cannot afford to walk away.
Should I fit out my phinisi in Indonesia or overseas?
For most budget to mid-range commissions, Indonesian fit-out (Bali, Surabaya, Batam) is practical and cost-effective. For vessels targeting international charter brokers and USD 8,000–20,000+/night gross rates — the Lamima tier — Thailand (Italthai and comparable Phuket facilities) offers superyacht-grade infrastructure that Indonesian yards do not yet match consistently. The decision hinges on your target charter market and the specification level that market requires. A vessel that will earn its living in the Indonesian domestic open-trip market has no business being fit out in Phuket; a vessel targeting Boat International’s charter listings has limited options domestically at the top of the spec range.
