A boat under 7 gross tonnes in NTB registers through the Pas Kecil route: the small-vessel registration handled at the local harbourmaster office (Syahbandar/KSOP/UPP) rather than through the full ship-registry process that larger vessels face. The sequence is short in principle — measurement to establish the tonnage, application with identity and ownership documents, then issue of the Pas Kecil as the boat’s registration certificate — and each step is straightforward when the paperwork arrives complete. This walkthrough covers the route step by step, the documents that actually get asked for, and the points where small-boat owners commonly stall.
First: confirm the boat really is under 7 GT
Gross tonnage is a volume measure, not a weight — a formula applied to the hull’s measured dimensions — and the 7 GT line is where Indonesian small-vessel administration changes character. Under 7 GT: Pas Kecil, local processing, simpler ongoing obligations. Over 7 GT: measurement certificate, registry deed and Pas Besar, processed at higher levels with more documentation — the route described in the Surat Ukur, Gross Akte and Pas Besar guide.
As a rule of thumb, open boats and small covered hulls up to roughly 10–12 m usually measure under 7 GT, but enclosed volume drives the number: a beamy 11 m hull with a full cabin can cross the line while a slender open 13 m hull stays under it. On a new build, the desk calculates expected tonnage at design stage precisely so the owner chooses the administrative class deliberately — sometimes a small design adjustment keeps a boat sensibly under the threshold, and sometimes the mission demands crossing it. Guessing is the one approach with no upside.
The step-by-step sequence
- Measurement (pengukuran). Apply to the local harbourmaster for measurement of the completed hull. An official measures length, breadth and depth and applies the small-vessel formula; the result documents the tonnage on which everything else rests. Have the boat accessible, complete and — ideally — with its builder documentation at hand.
- Prepare the ownership file. The consistent core: owner’s identity (KTP for individuals; deed, NPWP and licensing for a company), a builder’s certificate or statement (surat keterangan) from the yard attesting construction and first ownership, and where requested a village or kelurahan attestation supporting the ownership claim. On desk-managed builds, the yard’s handover pack is drafted to serve directly as this file — one of the small services that saves weeks, described on the after-sales page.
- Submit the application. The harbourmaster office processes the application against the measurement result and ownership file. Fees are modest and set by regulation (PNBP schedules); pay them at the counter against receipt — figures are quoted in IDR because that is what the state charges.
- Receive the Pas Kecil. The certificate records the boat’s identity, dimensions, tonnage and owner. Check every field on the spot — correcting a mis-typed name later costs more time than reading it now.
- Mark the boat. Registration identity goes on the hull as directed, and the certificate lives aboard, with copies ashore.
Timelines, honestly stated
With a complete file, the route commonly runs in a few weeks door to door; with an incomplete file it runs indefinitely, because each missing document restarts a queue. The stalls the desk sees most: builder’s statements missing because the boat was bought half-finished; identity documents not matching the intended registered owner (family-name registrations create sale complications years later); and boats presented for measurement unfinished, which produces provisional numbers and second visits. None of these are system failures — they are file failures, and all are preventable at the build stage.
What Pas Kecil does and does not authorise
Registration is identity, not permission. A Pas Kecil establishes the boat’s legal existence; it does not by itself authorise carrying paying passengers. Commercial operation adds its own layer — seaworthiness/safety documentation for the intended service, crew requirements, and the operating entity’s business licensing. Small tourism boats on the Gili trade operate under exactly this stack, and inspection regimes tightened meaningfully after past ferry and tour-boat incidents; treat the safety-equipment schedule in the NTB passenger-boat safety guide as the operating floor. For fishing hulls, fisheries licensing runs parallel through its own channels — context on the fishing boat build page.
Renewals, changes and the long file
The Pas Kecil carries a validity period and renews at the same office — a routine visit when the file is clean. Selling the boat, re-engining substantially, or modifying the hull enough to change its measured volume each trigger updates; owners who keep the certificate, measurement papers and builder documents together in one folder renew in a morning. Owners who scatter them re-create the file from scratch, which is the single most common self-inflicted delay in NTB small-boat administration.
Where this fits in a new build
On a supervised commission, registration is a scheduled build milestone, not an afterthought: tonnage calculated at design, the documentation pack assembled during fit-out, measurement booked as the boat completes, and the Pas Kecil in hand before or immediately after first launch — sequencing covered within the broader certification picture on the class and certification page. Foreign owners should note the registration must sit with an Indonesian person or entity, with the structural options laid out in can a foreigner commission a boat in Lombok.
The route rewards exactly one virtue: a complete file, presented once. Build the file with the boat and the Pas Kecil is the easiest paperwork the project will ever produce.
Frequently Asked Questions
What size boat stays under 7 GT?
Gross tonnage measures volume, not weight. Open boats and small covered hulls up to roughly 10–12 m usually measure under 7 GT, but enclosed volume drives the figure — a beamy 11 m hull with a full cabin can cross the line while a slender open 13 m hull stays under it. Calculate at design stage, never guess.
Where is a Pas Kecil issued?
At the local harbourmaster office — Syahbandar, KSOP or UPP — serving the boat’s home port. The office measures the hull, processes the application against the ownership file, collects the modest regulated fees in IDR, and issues the Pas Kecil recording the boat’s identity, dimensions, tonnage and owner.
What documents make up the ownership file?
Owner identity (KTP, or company deed with NPWP and licensing), a builder’s certificate or statement attesting construction and first ownership, and where requested a village attestation supporting the claim. On desk-managed builds the yard’s handover pack is drafted to serve directly as this file.
Does a Pas Kecil allow carrying paying passengers?
No — registration is identity, not permission. Commercial passenger service adds safety documentation for the intended route, crew requirements and the operator’s business licensing. Small Gili tourism boats operate under exactly that stack, and inspection regimes have tightened meaningfully in recent years.
