How Much Does It Cost to Build a Custom Phinisi in Sulawesi (2026)

The cost of a custom phinisi built in Sulawesi is driven by length and beam, interior specification, machinery and systems, classification ambition and finish quality. Yards quote against a written specification — a figure given before the specification exists is not a quotation, it is a conversation starter.

Why nobody can quote you a number in one line

Two 35-metre phinisi can differ by a wide margin because almost nothing about them is standard. Cabin count, air-conditioning load, generator redundancy, watermaker capacity, tender and davit arrangements, guest-facing joinery and whether the vessel is being built toward classification all move the total. The hull is the least costly part of the conversation.

The cost drivers, ranked

1. Length and beam. Everything scales from here — timber volume, systems capacity, crew numbers.
2. Interior specification. The single largest variable between a working charter boat and a premium guest vessel.
3. Machinery and systems. Engines, generators, watermaker, air conditioning, electrical architecture.
4. Classification and certification ambition. Building toward a class and passenger-certification framework costs more during construction and pays back at first survey and on resale.
5. Finish and fit-out. Joinery, fabrics, deck hardware, sanitary fittings.
6. Delivery. Getting the vessel from Sulawesi to its operating ground.

How to structure the contract

Payments tied to verifiable build milestones, not to the calendar. A written specification and general arrangement attached to the contract. Named owner’s representation with the right to inspect at each stage. Clear treatment of specification changes, because change orders are where budgets are lost. A defined delivery condition, including sea trials and the handover document set.

Build or buy?

Building gives you exactly the vessel you specified and no operating history to inherit. Buying gives you a hull you can survey and a season you can sell immediately. The comparison in commercial terms is in used steel liveaboard versus new phinisi.

Who to talk to

New construction belongs with the yards that build this type as their core trade — Bira phinisi builders and the Tana Beru yards. Construction, repair and refit contracts in this ecosystem are issued by PT Komodo Galangan Nusantara. This desk acts as liaison and owner-side sanity check, not as the builder — see phinisi for sale for completed vessels available now.
