How to Register a Yacht in Indonesia: Documents, Tonnage & Inspections

To register a boat in Indonesia you need five things: eligible ownership (an Indonesian citizen or legal entity), proof-of-ownership documents, a tonnage certificate (Surat Ukur), a registration deed (Grosse Akta Pendaftaran Kapal), and the safety and crew certificates that let the vessel sail. The framework sits under Shipping Law No. 17 of 2008, run by the Directorate General of Sea Transportation (Ditjen Hubla) through harbourmaster offices (KSOP); Bali owners deal mostly with KSOP Benoa.

Realistic timeline: two to four weeks to assemble the ownership file, then one to three months for measurement, registration and first certification, depending on the port and whether the vessel was imported. Any vessel of GT 7 or more must be registered; smaller boats use a regional Pas Kecil.

Who can register a vessel under the Indonesian flag

The registry is closed to direct foreign ownership. A vessel can only be registered to an Indonesian citizen or company; foreign buyers typically use an Indonesian PT, and cabotage rules add conditions once it carries paying passengers. The alternative is a foreign flag under temporary import, fine for personal use but not commercial charter. This is a tax and legal decision best settled before you buy; see our guide to yacht ownership structures and flag registration in Indonesia.

Step 1: Assemble the ownership documents

Registration starts with a clean paper trail proving how the vessel became yours. The registrar will ask for:

• Proof of ownership: a bill of sale, or a builder’s certificate for a new build.
• Deletion certificate: if flagged elsewhere, confirmation it has been struck off; you cannot hold two flags at once.
• Customs documentation: for imports, the declaration and proof duties were settled.
• Owner identity: KTP and tax number for individuals; establishment deed and NIB for a company.

If you are still buying, a pre-purchase survey protects the price and documents condition, information that resurfaces when the inspector comes aboard.

Step 2: Tonnage measurement and the Surat Ukur

Before anything is registered, the vessel must be officially measured. Vessels of 24 metres and over use the international method from the 1969 Tonnage Convention; smaller vessels use the domestic method. The resulting gross tonnage (GT) on the Surat Ukur drives everything downstream: nationality certificate, fees, manning and inspection regime.

Which certificate of nationality applies

Length does not predict tonnage; the band you fall into changes your paperwork.

Step 3: The registration deed (Grosse Akta)

Registration happens at a designated port, before the official registrar of vessels. The result is the Grosse Akta Pendaftaran Kapal, the closest thing a vessel has to a land title in Indonesia, recording identity, owner and basis of ownership, with registration marks fixed to the hull. It also matters at resale and financing: a ship mortgage (hipotek) is recorded against it, and it is the first thing a buyer’s lawyer checks. Keep the owner name and measurements consistent across every document.

Step 4: Safety inspections and statutory certificates

Flagged status alone does not authorise a vessel to sail; it needs current safety certification. Most yachts and phinisi fall under the Non-Convention Vessel Standard (NCVS), inspected by the harbourmaster’s marine inspectors, covering vessel safety, radio safety, load line and pollution prevention, with passenger-carrying vessels held to stricter rules plus annual renewals.

What inspectors actually check

Expect attention on life-saving appliances, fire-fighting equipment, navigation lights and hull condition. Most first-inspection failures are mundane: expired flares, lapsed extinguisher servicing, overdue liferaft repacks, or missing documentation for equipment already on board.

Step 5: Crew certification and manning

Every Indonesian-flagged vessel has a minimum safe manning requirement scaled to tonnage and area. Officers need certificates of competency, full STCW-pattern for larger vessels or domestic SKK for smaller ones, and crew need Basic Safety Training. Crew are entered in the crew register (sijil); lapsed crew paperwork is a frequent finding when officials board.

If the yacht will charter commercially

Registration makes the vessel Indonesian; it does not authorise commercial use. A yacht carrying paying guests needs business licensing through the OSS system, marine tourism or sea transport licensing for scheduled carriage, plus port clearance (SPB) per departure. Build this in early; retrofitting it later is slower and costlier.

Timeline and realistic costs

For a straightforward case, clean papers and a cooperative seller, plan on six weeks to three months to a fully certificated vessel. Imported yachts run longer, since the deletion certificate and customs clearance sit on the critical path. Government fees are modest; the real spend is professional: measurement, survey, notarial and agency handling, plus whatever equipment the inspection demands, usually the line that surprises people.

Getting it done without living at the port office

None of this is conceptually difficult, but it is sequential and spread across several offices, and one inconsistency between the deed, the measurement and the company papers can stall the file. As a Bali-based yacht brokerage, we coordinate registration, inspections and crew documentation with the agents and surveyors we work with across Bali and Labuan Bajo.
