Direct booking, transparent pricing, 24/7 in-trip support.
A commercial charter phinisi in Indonesia needs a stack of documents, not a single certificate: class approval from BKI, tonnage measurement, ship registration and a ship certificate (Pas Besar for larger vessels), GT-based safety and manning compliance, and a sea-transport business licence held by an Indonesian legal entity. Realistic planning time from launch to fully licensed operation is about 3–6 months. This page describes the process; specific article numbers, fees and capital requirements must be confirmed with Kemenhub, OSS and Indonesian maritime counsel before you rely on them.
- What it is: support through class survey, measurement, registration and operating licences.
- Who it is for: owners of new builds, conversions and imported or re-registered vessels.
- How long: 3–6 months after launch, on top of 12–18 months of construction.
- Key dependency: gross tonnage, which drives manning, safety equipment and certificate class.
Which certificates does a charter phinisi actually need?
Owners often arrive expecting one document. In practice the file has several layers, issued by different bodies, and they depend on each other in sequence.
| Item | Issued / handled by | Depends on | Typical timing |
|---|---|---|---|
| Build survey & plan approval | BKI (Biro Klasifikasi Indonesia) | Engineering package | During construction |
| Tonnage measurement (GT) | Kemenhub measurement office | Completed hull & superstructure | At or after launch |
| Ship registration & ownership deed | Kemenhub / registry port | Measurement, ownership documents | 2–8 weeks |
| Ship certificate (Pas Besar / Pas Kecil) | Kemenhub | Registration, GT band | 2–6 weeks |
| Class certificate | BKI | Survey, sea trial, stability booklet | After trials |
| Safety & equipment certificate | Kemenhub / class | Life rafts, firefighting, navigation | With class |
| Manning / crew certification | Kemenhub, crew training bodies | GT and voyage area | Parallel |
| Sea transport business licence | OSS / Kemenhub, held by an Indonesian entity | Company setup | Start early |
Indicative planning figures only — issuing offices, fees and processing times vary by port and by year, and we reconfirm each item at the time of application.
Who issues what — BKI, Kemenhub or your own company?
BKI is the Indonesian classification society. It reviews the structural and stability documentation, attends the vessel during construction and at trials, and issues class. International class — Lloyd’s Register, RINA, ABS or DNV — is an option on higher-spec builds and must be chosen before the scantling plan is frozen, because it changes structure, documentation and survey attendance.
Kemenhub, the Ministry of Transportation and its Directorate General of Sea Transportation, handles measurement, registration, the ship certificate, safety documentation and manning.
Your operating company holds the business licence. That company must be an Indonesian legal entity, because Indonesia applies cabotage: domestic sea transport is performed by Indonesian-flagged vessels. Foreign investors normally own and operate through a local company structure. We describe the shape of that arrangement and introduce maritime counsel — we do not publish capital thresholds, because they change and getting them wrong is expensive.
Why does gross tonnage matter so much?
GT is a measure of enclosed volume, not weight, and it is the number that determines your certificate class, your minimum manning, your safety equipment schedule and often your port fees. Two boats of the same length can land in different GT bands purely because one has an enclosed upper saloon and the other has an open deck. Natural Phinisi, at 21.38 m LOA with a 4.50 m beam, is published at 40 GT — a useful anchor for how quickly volume, not length, sets the number.
The practical consequence: arrangement decisions taken during design decide your regulatory burden for the life of the vessel. That is why the tonnage question belongs in the naval architecture and stability engineering stage, not at measurement.
What is the sequence from launch to first paying guest?
After launch the vessel is completed afloat, machinery is commissioned and dock trials are run. Sea trials follow, covering speed, manoeuvring, machinery under load, steering, anchoring and safety drills. An inclining experiment establishes lightship weight and centre of gravity so the stability booklet can be issued from measured data. Measurement, registration and the ship certificate follow, then safety and manning documentation, then the operating licence and any park or destination permits. Realistically that is 3–6 months, assuming documents are complete and surveyors are available — the single largest cause of delay we see is an incomplete ownership or import file, not a technical failure.
What documents should you have ready?
- Builder’s certificate and the build contract
- Approved general arrangement, lines plan, scantling plan and stability booklet
- Machinery and equipment certificates, including life rafts and firefighting
- Ownership documents for the Indonesian entity, deeds and tax registration
- Crew certificates matching the manning requirement
- Insurance cover notes — hull and machinery, plus passenger liability
- For conversions or purchases: previous registration, deletion certificate and survey history
Who is this service for?
Right for: first-time owners in Indonesia; foreign investors who need the process explained rather than assumed; and owners of converted vessels facing re-measurement and change-of-use survey — see cargo phinisi to liveaboard conversion.
Not needed: owners of small private craft outside commercial passenger rules, and operators with an existing in-house compliance team and an established registry relationship.
Frequently asked questions
What is BKI?
Biro Klasifikasi Indonesia, the national classification society. Indonesian-flag vessels are classed by BKI; international class is optional on higher-spec builds.
What is the difference between Pas Besar and Pas Kecil?
They are ship certificates issued according to vessel size band, with Pas Besar applying to larger vessels. Which one applies to your boat follows from measured gross tonnage, so it cannot be answered before measurement.
Can a foreigner register a boat in Indonesia?
Indonesia applies cabotage, so domestic sea transport uses Indonesian-flagged vessels and foreign investors typically own and operate through an Indonesian company. The structure is routine but it is legal work — confirm current requirements with counsel and OSS.
How long does certification take after the boat is finished?
Plan on 3–6 months as an estimate covering measurement, class survey, registration, safety documentation and licensing. It is not a guarantee; surveyor availability and document completeness drive it.
Does a refit require re-certification?
Structural work, machinery changes and anything altering gross tonnage or passenger capacity triggers survey and often re-measurement. Cosmetic work does not.
Do you handle Komodo National Park permits?
Park entry, conservation, ranger and harbour fees are set by the park authority, are subject to change, and are handled operationally rather than as part of certification. We always reconfirm current rates at booking rather than publishing one figure as definitive.
What crew certification is required?
Manning follows GT and voyage area, and each rank must hold valid certificates. Crew recruitment and training can be arranged under our charter management scope.
Can you certify a boat you did not build?
Yes. We regularly take on vessels built elsewhere, starting with a condition survey and a documentation gap analysis before committing to a timeline.
