Sulawesi yards can repair almost anything on a wooden hull — keel and frame sistering, plank replacement, re-caulking, sheathing, engine and shaft work — and the trigger for hauling out should be the survey cycle, not the breakdown. This page maps the repair scope, conversion work and the annual maintenance rhythm that keeps a hull in charter condition.
Answer first: what Sulawesi yards can repair, and when to haul out
The same shipwright skills that build hulls also rebuild them. Heritage-coast and hub-port yards handle structural timber repairs that many marinas elsewhere will not touch: replacing rot-affected keel sections, sistering or renewing frames, refastening and re-planking, traditional re-caulking, and protective sheathing. Hub yards add slipway capacity for engine, shaft and systems work. The discipline that separates cheap ownership from expensive ownership is timing: haul out on a schedule aligned to survey cycles and antifouling life — typically every 12–18 months for a working charter vessel in tropical water — and defects stay small. Wait for a leak to make the decision for you, and the same defect costs multiples more in yard time and lost charter weeks.
Repair scope
| Job | Method | Typical yard time | USD band |
|---|---|---|---|
| Keel section repair / partial replacement | Cut back to sound ulin, scarph in new certified timber, refasten | 3–8 weeks | Quoted per metre and access; the heaviest structural line item |
| Frame sistering or renewal | Sister alongside sound frames or steam/laminate replacements | 2–6 weeks depending on count | Per-frame pricing; economical when batched at haul-out |
| Plank replacement & refastening | Spile, fit and fasten matching species; refasten wasted zones | 1–4 weeks | Per plank/zone; species availability drives cost |
| Re-caulking & paying seams | Traditional cotton/compound caulking, seam paying, hardening off | 2–4 weeks full hull | Quoted per hull length; skilled crews are the constraint |
| Sheathing & antifouling | Epoxy or FRP sheathing over dry planking; tropical antifouling system | 2–5 weeks | Material-driven; see materials notes below |
| Engine, shaft & systems work | Alignment, stern gland, prop, generators, plumbing, electrics | 1–6 weeks | Parts logistics usually set the schedule, not labour |
Every structural repair begins with an inspection so the scope is evidence-based — the desk pairs each refit with an independent condition survey, and material comes through the same verified SVLK channels described on the timber sourcing page.
Conversions: cargo hull to liveaboard standard
Converting a traditional cargo phinisi into a passenger liveaboard is a recognised route into charter — and it is a bigger project than most buyers expect. Done properly it means: structural survey first, then stability assessment for the new deckhouse and tank arrangement, watertight subdivision review, guest accommodation build-out, new electrical and plumbing systems, safety equipment to passenger standards, and re-registration for the new service. The honest budget conversation is that a deep conversion can approach the cost of a purpose-built hull; the honest safety conversation is that stability work is not optional when you add a deckhouse. The desk scopes conversions with a surveyor and naval architect before any yard contract is signed.
Annual maintenance planning for year-round operation
Survey-cycle-aligned haul-outs
The efficient rhythm for a commercial vessel: an annual haul-out window of 2–4 weeks scheduled in the low season, scoped against the previous survey’s defect list, combining antifouling renewal, caulking touch-ups, fastener sampling, and machinery service — so that class or insurance survey requirements are satisfied in the same yard period rather than in a separate, revenue-killing second haul-out.
Tropical-water antifouling choices
Tropical fouling is aggressive; working vessels in Indonesian waters typically repaint antifouling every 12–18 months. The choice between conventional ablative systems and harder coatings depends on operating speed and haul-out access. On sheathed hulls, coating adhesion and sheathing condition are checked together; on unsheathed hulls, the antifouling cycle doubles as the borer-inspection cycle.
One planning note owners often miss: haul-out capacity is the real bottleneck, not labour. Slipways at the hub ports and tidal grids on the traditional coasts book out ahead of the low season, and structural timber jobs need covered or at least dry working weeks. Booking the slot before the defect list is final — and refining scope in the weeks before haul-out — beats waiting for a perfect work list and losing the season’s window entirely.

Send vessel type, LOA, location, and what you know of the work list (photos help). The desk matches the job to the right yard — heritage coast for structural timber work, hub ports for systems-heavy refits — and returns a scoped USD quotation with a realistic slot date. Refit engagements are contracted through PT Komodo Galangan Nusantara.
Frequently asked questions
What maintenance schedule should I plan for a wooden phinisi operating year-round?
The working pattern: daily crew checks (bilges, stern gland, rig), a monthly engineering day, and an annual low-season haul-out of 2–4 weeks covering antifouling, caulking touch-ups, fastener sampling and machinery service — aligned with survey and insurance requirements so one yard period covers everything.
How long can a well-maintained phinisi hull last in charter service?
Traditional hulls built from ulin, bitti and teak routinely serve for decades — working cargo phinisi from past generations are still afloat today. The variables are maintenance discipline and timely structural renewal: hulls that get their annual haul-outs and periodic refastening keep going; hulls that skip them age in dog years.
Bagaimana membuat phinisi aman untuk operasi diving dengan compressor dan ruang tanki?
Empat hal utama: kompresor dipasang di ruang berventilasi dengan intake udara bersih jauh dari knalpot; tabung dan ruang tanki diikat dengan rak yang kuat dan drainase baik; sistem kelistrikan tahan lembab dengan proteksi arus; dan penataan bobot (kompresor, tabung, weight) dihitung terhadap stabilitas kapal. Retrofit diving sebaiknya melalui review surveyor sebelum beroperasi.
Bagaimana tantangan asuransi untuk kapal kayu charter yang dibangun di shipyard tradisional?
Penanggung umumnya meminta condition survey terbaru, bukti perawatan terjadwal, dan kadang status klas atau kepatuhan NCVS. Kapal tradisional tanpa dokumen build lengkap tetap bisa diasuransikan, tetapi premi dan syaratnya lebih baik jika ada laporan survey independen, jadwal haul-out yang terbukti, dan dokumen registrasi yang rapi — persis paket yang disiapkan desk dalam program refit dan compliance.

Haul-out clusters and repair coasts are mapped in the island register.
Major works after delivery — annual maintenance once the vessel is based in Bali or Labuan Bajo, for example — are handed to ecosystem-level repair and refit coordination so the same standards follow the hull after launch.
