The clauses that actually protect an owner in a boat build contract Lombok context are those that remove ambiguity: a precise technical specification annex, a measurable milestone schedule, clear variation and delay procedures, balanced title and risk transfer, realistic warranty terms, and a practical dispute-resolution and governing-law clause tailored to Indonesian shipbuilding and flag-state requirements.
1. Scope of work and specification annexes
The most important protection is a written scope and technical specification that leaves as little as possible to interpretation. In Indonesian yards this usually consists of a build contract plus several annexes that surveyors, BKI and Kemenhub officials can work from during inspections.
What a protective specification should contain
- Principal particulars: length overall, beam, draft, material, hull form, propulsion type, design speed (as a planning value, not a guarantee).
- Structural scheme: frame spacing, keel and stem construction, scantlings for hull, deck, superstructure, bulkheads.
- Machinery and systems: engine make/model as a target, power band, gearboxes, shafts, props, steering, electrical, plumbing, fuel, grey/black water.
- Accommodation layout: cabin count, berths, wet areas, galley, crew spaces and finishes in broad terms.
- Regulatory intent: target flag, intended Kemenhub passenger certification, any owner-specified class rules for guidance.
Use drawings, equipment lists and system diagrams as annexes. The contract should give those annexes priority over marketing sketches or verbal conversations if there is any conflict.
2. Price structure, milestones and retention
Payment structure is where many owner protections are either created or lost. A clear milestone plan with retention on each stage can manage yard cashflow while keeping pressure on progress and quality.
Indicative milestone structure
Each project will differ, but an owner-focused contract in Lombok commonly breaks payments into steel/wood acquisition, hull, deck/superstructure, systems, interior and sea-trials. The table below is an example of how this can be expressed.
| Stage | Typical timing (months from start) | Indicative cumulative payment band (% of contract sum) |
|---|---|---|
| Contract signing & mobilisation | 0 | 5–15% |
| Hull structure completed | 3–8 | 25–35% |
| Deck & superstructure completed | 5–10 | 40–55% |
| Machinery & systems installed | 7–14 | 60–75% |
| Interior fit-out & systems commissioning | 9–18 | 80–90% |
| Sea-trials, defect list and delivery | 11–24 | 90–95% (with retention held) |
Retention and supervision
A retention—commonly 5–10% of the contract sum—held until completion of sea-trials and rectification of agreed defects motivates timely finishing. A separate clause can appoint an owner’s surveyor or representative, with defined rights to inspect and to sign-off on each milestone before payment is released. More detailed discussion of payment phasing and oversight appears under contract payment and supervision.
3. Variation and change-order procedure
Variations are where budgets drift. A protective contract sets out how changes to scope, materials or systems are requested, priced and approved, particularly when imported equipment is involved and lead times or exchange rates move.
Key variation elements
- Written instruction: all changes requested by the owner must be recorded in a signed variation order, not by WhatsApp only.
- Price and time effect: each variation should show an indicative cost band and any additional time-extension claim before the owner signs.
- Priority of changes: variations inconsistent with Kemenhub or BKI requirements must be adapted or refused, with reasons recorded.
- Prime-cost items: where exact models are not chosen at contract stage (e.g. galley equipment), allocate a reasonable allowance and update once brands and specifications are selected.
Without this procedure, informal “improvements” during the build can accumulate into significant additional cost and delay, often only disputed near delivery when leverage is limited.
4. Delay, extensions and liquidated damages
Yard and owner both need a clear definition of delay, legitimate grounds for time extension and the financial consequences of late completion. In Indonesia this sits alongside monsoon seasons, port closures and customs delays which are partly outside yard control.
Defining delay and extensions
- Baseline schedule: the contract should annex a Gantt-style build schedule with key dates, not just an overall month count.
- Permitted extensions: specific grounds such as force majeure events, late owner decisions, late variation payments, or regulatory inspections postponed by Syahbandar.
- Notification: yard must notify the owner in writing within a defined period if an event will impact completion date, with a proposed revised date.
Liquidated damages
Liquidated damages (LDs) are pre-agreed daily or weekly sums payable by the yard if completion is delayed beyond the adjusted delivery date for reasons within yard control. LDs should be commercially realistic, high enough to compensate some lost charter or financing costs but not so high that the clause is unenforceable or pushes a yard towards corner-cutting.
5. Title, risk and insurance
Ownership and risk do not have to pass together. A protective clause separates who owns the partially built vessel and who carries risk of loss or damage at each stage, and how this interfaces with Indonesian law and any mortgagee or financier requirements.
When title passes
- Progressive title transfer: a common approach is that title to work completed transfers to the owner as each milestone payment is made.
- Materials on site: the contract can state that materials and equipment identified for the vessel become the owner’s property once paid, even if not yet installed.
- Documents: rights to plan sets, calculations and drawings should be defined, particularly if the design is a semi-custom derivative.
Risk and insurance
- Risk in the yard: the yard usually carries risk of damage or loss until delivery and acceptance, and should insure accordingly.
- Owner-supplied items: if the owner supplies engines or special equipment, the contract should allocate risk and storage responsibility clearly.
- Trials and delivery voyage: clarify who insures the vessel during sea-trials and any delivery run from Lombok to the operational area.
6. Warranty, defect lists and after-delivery support
A protective warranty clause focuses on process and access, not just abstract months or years. It should cover how defects are identified, documented and remedied, especially when the vessel will operate away from Lombok for most of the year.
Defect liability period and scope
- Defect list at delivery: after sea-trials, owner and yard agree an itemised defect list. Retention is generally held until these are addressed.
- Warranty duration: typical bands are 6–18 months from delivery for structural and workmanship defects, with pass-through warranties for engines and branded equipment.
- Exclusions: normal wear, accidental damage, misuse, and modifications by third parties are commonly excluded.
Remedy mechanism
- Notice procedure: owner notifies defects in writing with photos and operating conditions.
- Rectification method: yard may repair on-site in Lombok, send technicians to the vessel, or approve a third-party repairer with cost-sharing defined in advance.
- Time to respond: contract should specify response times for urgent safety issues versus minor cosmetic items.
7. Governing law and dispute resolution
For a boat build contract Lombok project, governing law clauses that ignore Indonesian realities are unsafe. A protective contract names applicable law, identifies jurisdiction or arbitration venue, and builds in a structured escalation path before litigation.
Choosing law and forum
- Governing law: many owners opt for Indonesian law when the yard, construction site and regulators are Indonesian, sometimes combined with technical standards from another jurisdiction as guidance only.
- Court or arbitration: specify whether disputes go to Indonesian courts or to arbitration, and in which city. Arbitration can offer more technical decision-makers but involves additional cost.
Escalation steps
- Negotiation period: a defined period for management-level settlement efforts after a dispute notice.
- Expert determination: for narrow technical disputes (e.g. hull deflection, engine installation tolerances), an independent surveyor or naval architect can be appointed to give a non-binding or binding opinion.
- Language and documentation: specify contract language and which version prevails; in Indonesia a Bahasa Indonesia version is usually required, often alongside English.
8. Payment security and due diligence
Even the best-worded contract needs practical payment safeguards. Owners building in Lombok often live abroad, so cross-border transfers and supervision require careful structuring.
- Use staged transfers aligned with clearly defined milestones and inspection rights.
- Require invoices from the operating entity (PT Komodo Galangan Nusantara) consistent with the contract name and number.
- Consider escrow or custody arrangements for major instalments where appropriate.
- Ensure bank details are confirmed through more than one channel before large transfers.

Frequently asked questions
How detailed should the technical specification be in a Lombok build contract?
The specification should be detailed enough that a surveyor who has never met you could inspect the boat against it. That means clear principal dimensions, structural scantlings, system layouts, target machinery models or power bands, and equipment lists. Ambiguity is where disputes start; anything important to you operationally or commercially should appear in writing or on drawings.
Is it normal to include liquidated damages in an Indonesian boat build contract?
Including liquidated damages is common in more structured commercial and charter projects, and increasingly used for private vessels. The rate needs to be proportionate to the contract value and realistic for the yard to accept. Properly drafted LDs help focus both sides on maintaining the schedule and documenting any legitimate extensions of time.
Can I retain ownership of the design if the yard adapts an existing hull?
Yes, but it must be spelled out. If you commission a naval architect separately, your contract with the yard can grant a build licence for that design while confirming you retain intellectual property. Where the yard provides its own base design, ownership of any modifications and the right to reuse them on sisterships should be addressed explicitly.
What law is safest for enforcing a Lombok boat building agreement?
“Safest” depends on where the yard, owner, financiers and regulators sit. For a vessel physically built and documented in Indonesia, Indonesian law combined with a clear jurisdiction or arbitration venue is often the most practical. Trying to apply foreign law to a domestic shipyard and local authorities can create enforcement gaps and added cost.
How much retention should I hold back at delivery?
Retention bands of 5–10% of the contract sum are typical, but the exact figure depends on vessel size, complexity and the owner’s tolerance for risk. The key is linking retention release to objective events: completion of agreed defect lists after sea-trials, delivery of documentation, and handover of essential spares, not just a calendar date.
